Handling click events on a drawable within an EditText

I have added an im开发者_JAVA技巧age right of the text in an EditText widget, using the following XML:

<EditText
  android:id="@+id/txtsearch"
  ...
  android:layout_gravity="center_vertical"
  android:background="@layout/shape"
  android:hint="Enter place,city,state"
  android:drawableRight="@drawable/cross" />

But I want to clear the EditText when the embedded image is clicked. How can I do this?

Actually you don't need to extend any class. Let's say I have an EditText editComment with a drawableRight

editComment.setOnTouchListener(new OnTouchListener() {
    @Override
    public boolean onTouch(View v, MotionEvent event) {
        final int DRAWABLE_LEFT = 0;
        final int DRAWABLE_TOP = 1;
        final int DRAWABLE_RIGHT = 2;
        final int DRAWABLE_BOTTOM = 3;

        if(event.getAction() == MotionEvent.ACTION_UP) {
            if(event.getRawX() >= (editComment.getRight() - editComment.getCompoundDrawables()[DRAWABLE_RIGHT].getBounds().width())) {
                // your action here

                return true;
            }
        }
        return false;
    }
});

we getRawX() because we want to get the actual position of touch on screen, not relative to parent.

To get left side click

if(event.getRawX() <= (editComment.getCompoundDrawables()[DRAWABLE_LEFT].getBounds().width()))

Very, very good, thanks to everyone who contributed to this discussion. So if you don't want to deal with inconvenience of extending the class you can do the following (implemented for the right drawable only)

this.keyword = (AutoCompleteTextView) findViewById(R.id.search);
this.keyword.setOnTouchListener(new RightDrawableOnTouchListener(keyword) {
        @Override
        public boolean onDrawableTouch(final MotionEvent event) {
            return onClickSearch(keyword,event);
        }
    });

private boolean onClickSearch(final View view, MotionEvent event) {
    // do something
    event.setAction(MotionEvent.ACTION_CANCEL);
    return false;
}

And here's bare-bone listener implementation based on @Mark's answer

public abstract class RightDrawableOnTouchListener implements OnTouchListener {
    Drawable drawable;
    private int fuzz = 10;

    /**
     * @param keyword
     */
    public RightDrawableOnTouchListener(TextView view) {
        super();
        final Drawable[] drawables = view.getCompoundDrawables();
        if (drawables != null && drawables.length == 4)
            this.drawable = drawables[2];
    }

    /*
     * (non-Javadoc)
     * 
     * @see android.view.View.OnTouchListener#onTouch(android.view.View, android.view.MotionEvent)
     */
    @Override
    public boolean onTouch(final View v, final MotionEvent event) {
        if (event.getAction() == MotionEvent.ACTION_DOWN && drawable != null) {
            final int x = (int) event.getX();
            final int y = (int) event.getY();
            final Rect bounds = drawable.getBounds();
            if (x >= (v.getRight() - bounds.width() - fuzz) && x <= (v.getRight() - v.getPaddingRight() + fuzz)
                    && y >= (v.getPaddingTop() - fuzz) && y <= (v.getHeight() - v.getPaddingBottom()) + fuzz) {
                return onDrawableTouch(event);
            }
        }
        return false;
    }

    public abstract boolean onDrawableTouch(final MotionEvent event);

}

Consider the following. It's not the most elegant solution but it works, I just tested it.

1. Create a customized EditText class CustomEditText.java:

   import android.content.Context;
   import android.graphics.Rect;
   import android.graphics.drawable.Drawable;
   import android.util.AttributeSet;
   import android.view.MotionEvent;
   import android.widget.EditText;
   
   public class CustomEditText extends EditText
   {
     private Drawable dRight;
     private Rect rBounds;
   
     public CustomEditText(Context context, AttributeSet attrs, int defStyle) {
       super(context, attrs, defStyle);
     }
     public CustomEditText(Context context, AttributeSet attrs) {
       super(context, attrs);
     }
     public CustomEditText(Context context) {
       super(context);
     }
   
     @Override
     public void setCompoundDrawables(Drawable left, Drawable top,
         Drawable right, Drawable bottom)
     {
       if(right !=null)
       {
         dRight = right;
       }
       super.setCompoundDrawables(left, top, right, bottom);
     }
   
     @Override
     public boolean onTouchEvent(MotionEvent event)
     {
   
       if(event.getAction() == MotionEvent.ACTION_UP && dRight!=null)
       {
         rBounds = dRight.getBounds();
         final int x = (int)event.getX();
         final int y = (int)event.getY();
         //System.out.println("x:/y: "+x+"/"+y);
         //System.out.println("bounds: "+bounds.left+"/"+bounds.right+"/"+bounds.top+"/"+bounds.bottom);
         //check to make sure the touch event was within the bounds of the drawable
         if(x>=(this.getRight()-rBounds.width()) && x<=(this.getRight()-this.getPaddingRight())
             && y>=this.getPaddingTop() && y<=(this.getHeight()-this.getPaddingBottom()))
         {
           //System.out.println("touch");
           this.setText("");
           event.setAction(MotionEvent.ACTION_CANCEL);//use this to prevent the keyboard from coming up
         }
       }
       return super.onTouchEvent(event);
     }
   
     @Override
     protected void finalize() throws Throwable
     {
       dRight = null;
       rBounds = null;
       super.finalize();
     }
   }
   

2. Change your layout XML to this (where com.example is your actual project package name):

   <com.example.CustomEditText
       android:id="@+id/txtsearch"
       …
       android:layout_gravity="center_vertical"
       android:background="@layout/shape"
       android:hint="Enter place,city,state"
       android:drawableRight="@drawable/cross" 
   />
   

3. Finally, add this (or something similar) to your activity:

   …
   CustomEditText et = (CustomEditText) this.findViewById(R.id.txtsearch);
   …
   

I might be a bit off with the calculation of the touch bounds for the nested drawable but you get the idea.

I hope this helps.

I created a useful abstract class DrawableClickListener which implements OnTouchListener.

In addition to the DrawableClickListener class, I also created 4 additional abstract classes which extend the DrawableClickListener class and handle the clicking of the drawable area for the correct quadrant.

• LeftDrawableClickListener
• TopDrawableClickListener
• RightDrawableClickListener
• BottomDrawableClickListener

Point to Consider

One thing to consider is that the images are not resized if done this way; thus the images must be scaled correctly before being put into the res/drawable folder(s).

If you define a LinearLayout containing an ImageView and a TextView, it's a lot easier to manipulate the size of the image being displayed.

Kotlin is a great language where each class could be extended with new methods. Lets introduce new method for EditText class which will catch clicks to right drawable.

fun EditText.onRightDrawableClicked(onClicked: (view: EditText) -> Unit) {
this.setOnTouchListener { v, event ->
    var hasConsumed = false
    if (v is EditText) {
        if (event.x >= v.width - v.totalPaddingRight) {
            if (event.action == MotionEvent.ACTION_UP) {
                onClicked(this)
            }
            hasConsumed = true
        }
    }
    hasConsumed
}
}

You can see it takes callback function as argument which is called when user clicks to right drawable.

val username = findViewById<EditText>(R.id.username_text)
    username.onRightDrawableClicked {
        it.text.clear()
    }

---

Its very simple. Lets say you have a drawable on left side of your EditText 'txtsearch'. Following will do the trick.

EditText txtsearch = (EditText) findViewById(R.id.txtsearch);
txtsearch.setOnTouchListener(new OnTouchListener() {
    @Override
    public boolean onTouch(View v, MotionEvent event) {
        if(event.getAction() == MotionEvent.ACTION_UP) {
            if(event.getRawX() <= txtsearch.getTotalPaddingLeft()) {
                // your action for drawable click event

             return true;
            }
        }
        return false;
    }
});

If you want for right drawable change the if statement to:

if(event.getRawX() >= txtsearch.getRight() - txtsearch.getTotalPaddingRight())

Similarly, you can do it for all compound drawables.

txtsearch.getTotalPaddingTop()
txtsearch.getTotalPaddingBottom()

This method call returns all the padding on that side including any drawables. You can use this even for TextView, Button etc.

I think it is much more easier if we use some tricks :)

1. Create a image button with your icon and set its background color to be transparent.
2. Put the image button on the EditText and of coz the right hand side
3. Implement the onclick listener of the button to execute your function

Done

That last contribution's use of contains(x,y) won't work directly on the result of getBounds() (except, by coincidence, when using "left" drawables). The getBounds method only provides the Rect defining points of the drawable item normalized with origin at 0,0 - so, you actually need to do the math of the original post to find out if the click is in the area of the drawable in the context of the containing EditText's dimensions, but change it for top, right, left etc. Alternatively you could describe a Rect that has coordinates actually relative to its position in the EditText container and use contains(), although in the end you're doing the same math.

Combining them both gives you a pretty complete solution, I only added an instance attribute consumesEvent that lets the API user decide if the click event should be passed on or not by using its result to set ACTION_CANCEL or not.

Also, I can't see why the bounds and actionX, actionY values are instance attributes rather than just local on the stack.

Here's a cutout from an implementation based on the above that I put together. It fixes an issue that to properly consume the event you need to return false. It adds a "fuzz" factor to. In my use case of a Voice control icon in an EditText field, I found it hard to click, so the fuzz increases the effective bounds that are considered clicking the drawable. For me 15 worked well. I only needed drawableRight so I didn't plug the math in the others, to save some space, but you see the idea.

I have implemented in Kotlin

edPassword.setOnTouchListener { _, event ->
            val DRAWABLE_RIGHT = 2
            val DRAWABLE_LEFT = 0
            val DRAWABLE_TOP = 1
            val DRAWABLE_BOTTOM = 3
            if (event.action == MotionEvent.ACTION_UP) {
                if (event.rawX >= (edPassword.right - edPassword.compoundDrawables[DRAWABLE_RIGHT].bounds.width())) {
                    edPassword.setText("")
                    true
                }
            }
            false
        }

Extending on the idea by RyanM I have created a more flexible version, which supports all the drawable types (top, bottom, left, right). While the code below extends TextView, adapting it for an EditText is just a case of swapping "extends TextView" with "extends EditText". Instantiation the widget from XML is identical as in RyanM's example, bar the widget name.

public void setDrawableClickListener(DrawableClickListener listener) {
    this.clickListener = listener;
}}

---

The DrawableClickListener is as simple as this:

public interface DrawableClickListener {

public static enum DrawablePosition { TOP, BOTTOM, LEFT, RIGHT };
public void onClick(DrawablePosition target); }

---

And then the actual implementation:

class example implements DrawableClickListener {
public void onClick(DrawablePosition target) {
    switch (target) {
        case LEFT:
            doSomethingA();
            break;

        case RIGHT:
            doSomethingB();
            break;

        case BOTTOM:
            doSomethingC();
            break;

        case TOP:
            doSomethingD();
            break;

        default:
            break;
    }
}}

---

p.s.: If you don't set the listener, touching the TextView will cause a NullPointerException. You may want to add some more paranoia into the code.

---

its working for me,

mEditTextSearch.addTextChangedListener(new TextWatcher() {

        @Override
        public void onTextChanged(CharSequence s, int start, int before, int count) {
            if(s.length()>0){
                mEditTextSearch.setCompoundDrawablesWithIntrinsicBounds(null, null, getResources().getDrawable(android.R.drawable.ic_delete), null);
            }else{
                mEditTextSearch.setCompoundDrawablesWithIntrinsicBounds(null, null, getResources().getDrawable(R.drawable.abc_ic_search), null);
            }
        }
        @Override
        public void beforeTextChanged(CharSequence s, int start, int count, int after) {
        }
        @Override
        public void afterTextChanged(Editable s) {
        }
    });
    mEditTextSearch.setOnTouchListener(new OnTouchListener() {
        @SuppressLint("ClickableViewAccessibility")
        @Override
        public boolean onTouch(View v, MotionEvent event) {
            if(event.getAction() == MotionEvent.ACTION_UP) {
                if(mEditTextSearch.getCompoundDrawables()[2]!=null){
                    if(event.getX() >= (mEditTextSearch.getRight()- mEditTextSearch.getLeft() - mEditTextSearch.getCompoundDrawables()[2].getBounds().width())) {
                        mEditTextSearch.setText("");
                    }
                }
            }
            return false;
        }
    });

I know this is quite old, but I recently had to do something similar... After seeing how difficult this is, I came up with a much simpler solution:

1. Create an XML layout that contains the EditText and Image
2. Subclass FrameLayout and inflate the XML layout
3. Add code for the click listener and any other behavior you want

In my case, I needed an EditText that had the ability to clear the text with a button. I wanted it to look like SearchView, but for a number of reasons I didn't want to use that class. The example below shows how I accomplished this. Even though it doesn't have to do with focus change, the principles are the same and I figured it would be more beneficial to post actual working code than to put together an example that may not work exactly as I intended:

Here is my layout: clearable_edit_text.xml

<merge
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content">

    <EditText
        android:id="@+id/edit_text_field"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"/>

    <!-- NOTE: Visibility cannot be set to "gone" or the padding won't get set properly in code -->
    <ImageButton
        android:id="@+id/edit_text_clear"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="right|center_vertical"
        android:background="@drawable/ic_cancel_x"
        android:visibility="invisible"/>
</merge>

And here is the Class that inflates that layout: ClearableEditText.java

public class ClearableEditText extends FrameLayout {
    private boolean mPaddingSet = false;

    /**
     * Creates a new instance of this class.
     * @param context The context used to create the instance
     */
    public ClearableEditText (final Context context) {
        this(context, null, 0);
    }

    /**
     * Creates a new instance of this class.
     * @param context The context used to create the instance
     * @param attrs The attribute set used to customize this instance
     */
    public ClearableEditText (final Context context, final AttributeSet attrs) {
        this(context, attrs, 0);
    }

    /**
     * Creates a new instance of this class.
     * @param context The context used to create the instance
     * @param attrs The attribute set used to customize this instance
     * @param defStyle The default style to be applied to this instance
     */
    public ClearableEditText (final Context context, final AttributeSet attrs, final int defStyle) {
        super(context, attrs, defStyle);

        final LayoutInflater inflater = LayoutInflater.from(context);
        inflater.inflate(R.layout.clearable_edit_text, this, true);
    }

    @Override
    protected void onFinishInflate () {
        super.onFinishInflate();

        final EditText editField = (EditText) findViewById(R.id.edit_text_field);
        final ImageButton clearButton = (ImageButton) findViewById(R.id.edit_text_clear);

        //Set text listener so we can show/hide the close button based on whether or not it has text
        editField.addTextChangedListener(new TextWatcher() {
            @Override
            public void beforeTextChanged (final CharSequence charSequence, final int i, final int i2, final int i3) {
                //Do nothing here
            }

            @Override
            public void onTextChanged (final CharSequence charSequence, final int i, final int i2, final int i3) {
                //Do nothing here
            }

            @Override
            public void afterTextChanged (final Editable editable) {
                clearButton.setVisibility(editable.length() > 0 ? View.VISIBLE : View.INVISIBLE);
            }
        });

        //Set the click listener for the button to clear the text. The act of clearing the text will hide this button because of the
        //text listener
        clearButton.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick (final View view) {
                editField.setText("");
            }
        });
    }

    @Override
    protected void onLayout (final boolean changed, final int left, final int top, final int right, final int bottom) {
        super.onLayout(changed, left, top, right, bottom);

        //Set padding here in the code so the text doesn't run into the close button. This could be done in the XML layout, but then if
        //the size of the image changes then we constantly need to tweak the padding when the image changes. This way it happens automatically
        if (!mPaddingSet) {
            final EditText editField = (EditText) findViewById(R.id.edit_text_field);
            final ImageButton clearButton = (ImageButton) findViewById(R.id.edit_text_clear);

            editField.setPadding(editField.getPaddingLeft(), editField.getPaddingTop(), clearButton.getWidth(), editField.getPaddingBottom());
            mPaddingSet = true;
        }
    }
}

To make this answer more in line with the question the following steps should be taken:

1. Change the drawable resource to whatever you want... In my case it was a gray X
2. Add a focus change listener to the edit text...

---

Simply copy paste the following code and it does the trick.

editMsg.setOnTouchListener(new View.OnTouchListener() {
        @Override
        public boolean onTouch(View v, MotionEvent event) {
            final int DRAWABLE_LEFT = 0;
            final int DRAWABLE_TOP = 1;
            final int DRAWABLE_RIGHT = 2;
            final int DRAWABLE_BOTTOM = 3;

            if(event.getAction() == MotionEvent.ACTION_UP) {
                if(event.getRawX() >= (editMsg.getRight() - editMsg.getCompoundDrawables()[DRAWABLE_RIGHT].getBounds().width())) {
                    // your action here

                    Toast.makeText(ChatActivity.this, "Message Sent", Toast.LENGTH_SHORT).show();
                    return true;
                }
            }
            return false;
        }
    });

---

None of the previous solutions worked for me in Xamarin Android. I was able to get the right drawable click listener working using the following:

Create the following OnEditTextTouch event listener:

  private void OnEditTextTouch(object sender, View.TouchEventArgs e)
    {
        var rightDrawable = _autoCompleteTextViewSearch.GetCompoundDrawables()[2];

        if (rightDrawable == null || e.Event.Action != MotionEventActions.Up)
        {
            e.Handled = false;

            return;
        }

        if (e.Event.GetX() >= _autoCompleteTextViewSearch.Width - _autoCompleteTextViewSearch.TotalPaddingRight)
        {
            // Invoke your desired action here.

            e.Handled = true;
        }

        // Forward the event along to the sender (crucial for default behaviour)
        (sender as AutoCompleteTextView)?.OnTouchEvent(e.Event);
    }

Subscribe to the Touch event:

_autoCompleteTextViewSearch.Touch += OnEditTextTouch;

---

I've taked the solution of @AZ_ and converted it in a kotlin extension function:

So copy this in your code:

@SuppressLint("ClickableViewAccessibility")
fun EditText.setDrawableRightTouch(setClickListener: () -> Unit) {
    this.setOnTouchListener(View.OnTouchListener { _, event ->
        val DRAWABLE_LEFT = 0
        val DRAWABLE_TOP = 1
        val DRAWABLE_RIGHT = 2
        val DRAWABLE_BOTTOM = 3
        if (event.action == MotionEvent.ACTION_UP) {
            if (event.rawX >= this.right - this.compoundDrawables[DRAWABLE_RIGHT].bounds.width()
            ) {
                setClickListener()
                return@OnTouchListener true
            }
        }
        false
    })
}

You can use it just calling the setDrawableRightTouch function on your EditText:

yourEditText.setDrawableRightTouch {
    //your code
}

A probable solution to the above problem could be using android's new material component TextInputLayout.

<com.google.android.material.textfield.TextInputLayout
                    android:id="@+id/searchInput"
                    style="@style/Widget.App.TextInputLayout"
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"
                    android:hint="@string/search"
                    app:endIconMode="custom"
                    app:endIconContentDescription="Search"
                    app:endIconDrawable="@drawable/ic_search">

                    <EditText
                        android:id="@+id/et_search"
                        android:layout_width="match_parent"
                        android:layout_height="match_parent"/>

                </com.google.android.material.textfield.TextInputLayout>

Here the TextInputLayout attribute endIconMode when set, places a button at the end of the enclosed EditText.

Additionally app:endIconMode = "custom" allows customization of the icon's click functonality

Finally to listen to the end icon clicks call setEndIconClickListener() on the enclosing TextInputLayout component.

@Override
    public boolean onTouch(View v, MotionEvent event) {

        Drawable drawableObj = getResources().getDrawable(R.drawable.search_btn);
        int drawableWidth = drawableObj.getIntrinsicWidth();

        int x = (int) event.getX();
        int y = (int) event.getY();

        if (event != null && event.getAction() == MotionEvent.ACTION_UP) {
            if (x >= (searchPanel_search.getWidth() - drawableWidth - searchPanel_search.getPaddingRight())
                    && x <= (searchPanel_search.getWidth() - searchPanel_search.getPaddingRight())

                    && y >= searchPanel_search.getPaddingTop() && y <= (searchPanel_search.getHeight() - searchPanel_search.getPaddingBottom())) {

                getSearchData();
            }

            else {
                InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
                imm.showSoftInput(searchPanel_search, InputMethodManager.SHOW_FORCED);
            }
        }
        return super.onTouchEvent(event);

    }

and if drawable is on the left, this will help you. (for those work with RTL layout)

 editComment.setOnTouchListener(new OnTouchListener() {
        @Override
        public boolean onTouch(View v, MotionEvent event) {
            final int DRAWABLE_LEFT = 0;
            final int DRAWABLE_TOP = 1;
            final int DRAWABLE_RIGHT = 2;
            final int DRAWABLE_BOTTOM = 3;

            if(event.getAction() == MotionEvent.ACTION_UP) {
                if (event.getRawX() <= (searchbox.getLeft() + searchbox.getCompoundDrawables()[DRAWABLE_LEFT].getBounds().width())) {
                                     // your action here

                 return true;
                }
            }
            return false;
        }
    });

It is all great but why not to make it really simple?

I have faced with that also not so long ago...and android touchlistiner works great but gives limitation in usage..and I came to another solution and I hope that will help you:

    <LinearLayout
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:id="@+id/zero_row">
    <LinearLayout
        android:orientation="horizontal"
        android:layout_width="match_parent"
        android:layout_height="match_parent">
        <LinearLayout
            android:orientation="horizontal"
            android:layout_width="wrap_content"
            android:layout_height="match_parent">
            <ProgressBar
                android:id="@+id/loadingProgressBar"
                android:layout_gravity="center"
                android:layout_width="28dp"
                android:layout_height="28dp" />
        </LinearLayout>
        <LinearLayout
            android:orientation="horizontal"
            android:layout_width="match_parent"
            android:background="@drawable/edittext_round_corners"
            android:layout_height="match_parent"
            android:layout_marginLeft="5dp">
            <ImageView
                android:layout_width="28dp"
                android:layout_height="28dp"
                app:srcCompat="@android:drawable/ic_menu_search"
                android:id="@+id/imageView2"
                android:layout_weight="0.15"
                android:layout_gravity="center|right"
                android:onClick="OnDatabaseSearchEvent" />
            <EditText
                android:minHeight="40dp"
                android:layout_marginLeft="10dp"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:background="@drawable/edittext_round_corners"
                android:inputType="textPersonName"
                android:hint="Search.."
                android:textColorHint="@color/AndroidWhite"
                android:textColor="@color/AndroidWhite"
                android:ems="10"
                android:id="@+id/e_d_search"
                android:textCursorDrawable="@color/AndroidWhite"
                android:layout_weight="1" />
            <ImageView
                android:layout_width="28dp"
                android:layout_height="28dp"
                app:srcCompat="@drawable/ic_oculi_remove2"
                android:id="@+id/imageView3"
                android:layout_gravity="center|left"
                android:layout_weight="0.15"
                android:onClick="onSearchEditTextCancel" />
        </LinearLayout>

        <!--android:drawableLeft="@android:drawable/ic_menu_search"-->
        <!--android:drawableRight="@drawable/ic_oculi_remove2"-->

    </LinearLayout>

</LinearLayout>

Now you can create ImageClick listener or event and do what ever you want with text. This edittext_round_corners.xml file

<item android:state_pressed="false" android:state_focused="false">
    <shape>
        <gradient
            android:centerY="0.2"
            android:startColor="@color/colorAccent"
            android:centerColor="@color/colorAccent"
            android:endColor="@color/colorAccent"
            android:angle="270"
            />
        <stroke
            android:width="0.7dp"
            android:color="@color/colorAccent" />
        <corners
            android:radius="5dp" />
    </shape>
</item>

Better to have ImageButton on Right of edit text and give negative layout margin to overlap with edit text. Set listener on ImageButton and perform operations.

---

<FrameLayout
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:padding="5dp" >

            <EditText
                android:id="@+id/edt_status_text"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_marginBottom="10dp"
                android:background="@drawable/txt_box_blank"
                android:ems="10"
                android:hint="@string/statusnote"
                android:paddingLeft="5dp"
                android:paddingRight="10dp"
                android:textColor="@android:color/black" />

            <Button
                android:id="@+id/note_del"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_gravity="right"
                android:layout_marginRight="1dp"
                android:layout_marginTop="5dp"
                android:background="@android:drawable/ic_delete" />
        </FrameLayout>

Compound drawables are not supposed to be clickable. It is cleaner to use separate views in a horizontal LinearLayout and use a click handler on them.

<LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginTop="15dp"
        android:background="@color/white"
        android:layout_marginLeft="20dp"
        android:layout_marginStart="20dp"
        android:layout_marginRight="20dp"
        android:layout_marginEnd="20dp"
        android:layout_gravity="center_horizontal"
        android:orientation="horizontal"
        android:translationZ="4dp">

        <ImageView
            android:layout_width="wrap_content"
            android:layout_height="match_parent"
            android:background="@color/white"
            android:minWidth="40dp"
            android:scaleType="center"
            app:srcCompat="@drawable/ic_search_map"/>

        <android.support.design.widget.TextInputEditText
            android:id="@+id/search_edit"
            style="@style/EditText.Registration.Map"
            android:layout_width="0dp"
            android:layout_weight="1"
            android:layout_height="wrap_content"
            android:hint="@string/hint_location_search"
            android:imeOptions="actionSearch"
            android:inputType="textPostalAddress"
            android:maxLines="1"
            android:minHeight="40dp" />

        <ImageView
            android:id="@+id/location_gps_refresh"
            android:layout_width="wrap_content"
            android:layout_height="match_parent"
            android:background="@color/white"
            android:minWidth="40dp"
            android:scaleType="center"
            app:srcCompat="@drawable/selector_ic_gps"/>
</LinearLayout>

For anyone who does not want to implement the monstrous click handling. You can achieve the same with a RelativeLayout. With that you even have free handling of the positioning of the drawable.

  <RelativeLayout
     android:layout_width="match_parent"
     android:layout_height="wrap_content">

   <android.support.design.widget.TextInputLayout
      android:layout_width="match_parent"
      android:layout_height="wrap_content">

     <android.support.design.widget.TextInputEditText
       android:layout_width="match_parent"
       android:layout_height="wrap_content"
      />
     </android.support.design.widget.TextInputLayout>
     <ImageView
       android:layout_width="wrap_content"
       android:layout_height="wrap_content"
       android:layout_alignParentEnd="true"
       android:layout_centerInParent="true"
       android:src="@drawable/ic_undo"/>
    </RelativeLayout>

The ImageView position will be the same as you would use drawableEnd - plus you don't need all the touch listener handling. Just a click listener for the ImageView and you are good to go.

This works fro me:) may this help you as well

edit_account_name.setOnTouchListener(new View.OnTouchListener() {
        @Override
        public boolean onTouch(View v, MotionEvent event) {
            if (event.getAction() == MotionEvent.ACTION_DOWN) {
                if (event.getRawX() >= (edit_account_name.getRight())) {
                    //clicked
                   return true;
                }
            }
            return false;
        }
    });

I've seen several solutions but I wasn't convinced by any of them. Either very complicated or too simple (non-reusable).

This is my favourite approach at the moment:

mEditText.setOnTouchListener(
        new OnEditTextRightDrawableTouchListener(mEditText) {
          @Override
          public void OnDrawableClick() {
            // The right drawable was clicked. Your action goes here.
          }
        });

And this is the reusable touch listener:

import android.graphics.drawable.Drawable;
import android.support.annotation.NonNull;
import android.view.MotionEvent;
import android.view.View;
import android.view.View.OnTouchListener;
import android.widget.EditText;

public abstract class OnEditTextRightDrawableTouchListener implements OnTouchListener {

  private final EditText mEditText;

  public OnEditTextRightDrawableTouchListener(@NonNull final EditText editText) {
    mEditText = editText;
  }

  @Override
  public boolean onTouch(View view, MotionEvent motionEvent) {
    if (motionEvent.getAction() == MotionEvent.ACTION_UP) {
      final int DRAWABLE_RIGHT_POSITION = 2;
      final Drawable drawable = mEditText.getCompoundDrawables()[DRAWABLE_RIGHT_POSITION];
      if (drawable != null) {
        final float touchEventX = motionEvent.getX();
        final int touchAreaRight = mEditText.getRight();
        final int touchAreaLeft = touchAreaRight - drawable.getBounds().width();
        if (touchEventX >= touchAreaLeft && touchEventX <= touchAreaRight) {
          view.performClick();
          OnDrawableClick();
        }
        return true;
      }
    }
    return false;
  }

  public abstract void OnDrawableClick();
}

You can look at the Gist here.

Follow below code for drawable right,left,up,down click:

edittextview_confirmpassword.setOnTouchListener(new View.OnTouchListener() {
    @Override        public boolean onTouch(View v, MotionEvent event) {
        final int DRAWABLE_LEFT = 0;
        final int DRAWABLE_TOP = 1;
        final int DRAWABLE_RIGHT = 2;
        final int DRAWABLE_BOTTOM = 3;

        if(event.getAction() == MotionEvent.ACTION_UP) {
            if(event.getRawX() >= (edittextview_confirmpassword.getRight() - edittextview_confirmpassword.getCompoundDrawables()[DRAWABLE_RIGHT].getBounds().width())) {
                // your action here                    edittextview_confirmpassword.setInputType(InputType.TYPE_CLASS_TEXT | InputType.TYPE_TEXT_VARIATION_PASSWORD);
                return true;
            }
        }else{
            edittextview_confirmpassword.setInputType(InputType.TYPE_CLASS_TEXT | InputType.TYPE_TEXT_FLAG_NO_SUGGESTIONS);

        }
        return false;
    }
});

}

---

Here's my simple solution, just place ImageButton over EditText:

<RelativeLayout
  android:layout_width="match_parent"
  android:layout_height="wrap_content">

  <EditText android:id="@+id/editTextName"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:imeOptions="actionSearch"
    android:inputType="text"/>

  <ImageButton android:id="@+id/imageViewSearch"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:src="@drawable/ic_action_search"
    android:layout_alignParentRight="true"
    android:layout_centerVertical="true"/>

</RelativeLayout>

---

for left drawable click listener

txt.setOnTouchListener(new View.OnTouchListener() {
        @Override
        public boolean onTouch(View v, MotionEvent event) {
            final int DRAWABLE_LEFT = 0;

            if (event.getAction() == MotionEvent.ACTION_UP) {
                if (event.getRawX() <= (txt
                        .getCompoundDrawables()[DRAWABLE_LEFT].getBounds().width() +
                        txt.getPaddingLeft() +
                        txt.getLeft())) {

                          //TODO do code here
                    }
                    return true;
                }
            }
            return false;
        }
    });

---

I would like to suggest a way for drawable left! I tried this code and works.

txtsearch.setOnTouchListener(new View.OnTouchListener() {
        @Override
        public boolean onTouch(View view, MotionEvent event) {
            final int DRAWABLE_LEFT = 0;
            int start=txtsearch.getSelectionStart();
            int end=txtsearch.getSelectionEnd();
            if(event.getAction() == MotionEvent.ACTION_UP) {
                if(event.getRawX() <= (txtsearch.getLeft() + txtsearch.getCompoundDrawables()[DRAWABLE_LEFT].getBounds().width())) {
                    //Do your action here
                    return true;
                }

            }
            return false;
        }
    });
}

I implemented @aristo_sh answer in Mono.Droid (Xamarin), since it's a delegate anonymous method you can't return true or false you have to take take of e.Event.Handled. I am also hiding the keyboard on click

editText.Touch += (sender, e) => {
                    e.Handled = false;
                    if (e.Event.Action == MotionEventActions.Up)
                    {
                        if (e.Event.RawX >= (bibEditText.Right - (bibEditText.GetCompoundDrawables()[2]).Bounds.Width()))
                        {
                            SearchRunner();
                            InputMethodManager manager = (InputMethodManager)GetSystemService(InputMethodService);
                            manager.HideSoftInputFromWindow(editText.WindowToken, 0);
                            e.Handled = true;
                        }
                    }
                };
