one hack could be to hide the action mode asap like

 @Override
    public void onActionModeStarted(ActionMode mode) {
        super.onActionModeStarted(mode);
        mode.finish();
    }

public class TextViewA extends TextView {

    @Override
    protected void onCreateContextMenu(ContextMenu menu) {
        super.onCreateContextMenu(menu);
        setCustomSelectionActionModeCallback(new MarkTextSelectionActionModeCallback());
    }



public TextViewA(Context context) {
    super(context);
}
public TextViewA(Context context,AttributeSet attrs) {
    super(context,attrs);
}
public TextViewA(Context context, AttributeSet attrs, int defStyle){
    super(context, attrs, defStyle);
}

Here the xml

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

  <br.com.vrbsm.textviewexample.TextViewA
      android:id="@+id/textView2" 
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      android:textIsSelectable="true"
      android:textSize="12dp"
      />
</RelativeLayout>

here main

public class MainActivity extends Activity{
//  
    private TextViewA textview;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main_activity);

        textview = (TextViewA)findViewById(R.id.textView2);
        textview.setText("Android is crazy");

    }


public class MarkTextSelectionActionModeCallback implements Callback {

Try this:

 public class CustomActionModeTextView extends TextView{

       //...implement your constructors as you may want to use...//
       @Override
       public ActionMode.Callback getCustomSelectionActionModeCallback (){
          return new MarkTextSelectionActionModeCallback();
        }


 }

Create your own TextView and override the method getCustomSelectionActioModeCallback to return always an instance of your custom action mode callback. This way you don't have to set it everytime in your views.

Remember

  • Use your custom class in your XML layout files;
  • When casting it, do the cast to your custom class and not TextView;
  • You may wanna consider keeping a reference to your custom callback in your class. You could initialize it during some constructor and return it in the get method. This would be just to avoid creating new instances on every method call.
