How to show contextmenu on inflated view?

I want to display contextmenu for an inflated view. Here is the code sample:

for grid_layout.xml:

<?xml version="1.0" encoding="utf-8"?>    
    <ImageView
            xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/icon"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:scaleType="centerInside"
        android:antialias="true" />

Now I am using it in my activiy class as:

  @Override
    public void onCreateContextMenu(ContextMenu menu, View v, ContextMenuInfo menuInfo) {       
            menu.setHeaderTitle("Select action");       
            menu.add(0, 1, 0, "Action1");
            menu.add(0, 2, 0, "Action2");

            super.onCreateContextMenu(menu, v, menuInfo);
    }

    LayoutInflater inflater = (LayoutInflater) getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);

    ImageView imageView = (ImageView) inflater.inflate(R.layout.grid_layout, null);
    imageView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
               registerForContextMenu(v);
                       openContextMenu(v);
            }

        });

This code runs without any error but the context menu does not show up when I click the imageView. Is there anything wrong with this code?开发者_运维百科

I have found a workaround for this situation and solved my problem. As I told that the same code works fine and displays the ContextMenu, if I define the ImageView in the XML which I set in setContentView() method. I simply used the object of that imageView to register the contextMenu and displayed the ContextMenu on click of inflated item. Here is the sample code:

@Override
public void onCreateContextMenu(ContextMenu menu, View v, ContextMenuInfo menuInfo) {       
            menu.setHeaderTitle("Select action");       
            menu.add(0, 1, 0, "Action1");
            menu.add(0, 2, 0, "Action2");

            super.onCreateContextMenu(menu, v, menuInfo);
    }

    ImageView imageViewInContext = (ImageView) findViewById(R.id.imageview_in_main_xml);
    registerForContextMenu(imageViewInContext);

    LayoutInflater inflater = (LayoutInflater) getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);

    ImageView imageView = (ImageView) inflater.inflate(R.layout.grid_layout, null);
    imageView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {                   
                 openContextMenu(imageViewInContext);
            }

        });

Hope this will help someone!

Add in your code:

imageView.setFocusable(true);
imageView.setClickable(true);

after that Imageview will get clickEvent.

Because you are creating an Anonymous Inner Class (by doing new View.OnClickListener) you are no longer operating in the UI thread (your Activity class), so the context menu does not load when you want to registerForContextMenu and openContextMenu. You can either use a Handler to send a message to the UI thread(your Activity class) to perform these actions, or try to reference your Activity class in your inner class. Something like this:

activityClassName.this.registerForContextMenu(v);
activityClassName.this.openContextMenu(v);
