Facing problem in implementing OnClickListener on android

I want to implement a click listener for a button on my main view. My code is something like below

protected void onCreate(Bundle savedValues) {
    ...
    // Capture our button from layout
    Button button = (Button)findViewById(R.id.btnFinish);
    // Register the onClick listener with the implementation above
    button.setOnClickListener(mFinishListener);
    ...
}

private OnClickListener mFinishListener = new OnClickListener() {
    public void onClick(View v) {
      // do something when the button is clicked
    }
};

But shows me error as follows

The method se开发者_JAVA百科tOnClickListener(View.OnClickListener) in the type View is not applicable for the arguments (DialogInterface.OnClickListener)  MobileTrackerActivity.java  /MobileTracker/src/com/example/mobiletracker    line 37 Java Problem

I have no idea what to do. Please help.

You are not using the correct interface to instantiate the mFinishLinstener variable...

It is possible you have an import specifying DialogInterface and that is confusing the view.

Try specifying View.OnClickListener explicitly.

private View.OnClickListener mFinishListener = new View.OnClickListener() {
    public void onClick(View v) {
      // do something when the button is clicked
    }
};

As per my opinion Best way to implement On click event for the Button.

Instead of applying an OnClickListener to the button in your activity, you can assign a method to your button in the XML layout, using the android:onClick attribute. For example:

 <Button
     android:layout_height="wrap_content"
     android:layout_width="wrap_content"
     android:text="@string/self_destruct"
     android:onClick="selfDestruct" />

Now, when a user clicks the button, the Android system calls the activity's selfDestruct(View) method. In order for this to work, the method must be public and accept a View as its only parameter. For example:

public void selfDestruct(View view) {
     // Kabloey
 }

Note: The above code is given in Android SDK - Button.

try this code :::

final Button button = (Button) findViewById(R.id.btnFinish);
         button.setOnClickListener(new View.OnClickListener() {
             public void onClick(View v) {
                 // Perform action on click
             }
         });

---

Simply try this one as:

 button.setOnClickListener(new OnClickListener() {  
@Override   
 public void onClick(View v) {
      // do something when the button is clicked
    }
};

---

you can also use like below code..

Button button = (Button)findViewById(R.id.btnFinish);

button.setOnClickListener(new View.OnClickListener(){
@Override
public void onClick(View v)
{
   //Write Your code here
}
});

---

You can also declare the onclick in the xml.

<Button android:layout_width="wrap_content" android:layout_height="wrap_content" android:onclick="buttonClick" />

And in your code you would define the function as:

public void buttonClick(View view)
{
    // handle click
}
