How to detect doubletap on a View? [duplicate]

I'm trying to have a View sensitive to double taps on an Android. So far, I learned to set up the double tap and know what place to handle the event for action:
API: android.view.GestureDetector.OnDoubleTapListener private GestureDetector mGestureDetector;
…
mGestureDetector = new GestureDetector(this);
…
mGestureDetector.setOnDoubleTapListener(new MyDoubleTapListener());
…
private class MyDoubleTapListener implements GestureDetector.OnDoubleTapListener {
public boolean onDoubleTapEvent(MotionEvent e) {
return false;
}
@Override
public boolean onDoubleTap(MotionEvent e) {
// TODO Auto-generated method stub
return false;
}
@Override
public boolean onSingleTapConfirmed(MotionEvent e) {
// TODO Auto-generated method stub
return false;
}
}
But How do I link it to the View? This is in a class that has a few View members.
I'll really appreciate you helping me connect the dots!
Your view needs to implement the onTouchEvent() method, and that method needs to pass the event along to the onTouchEvent() method of the GestureDetector object.
@Override
public boolean onTouchEvent(MotionEvent event)
{
Log.v(DEBUG_TAG,"OnTouchEvent !!!");
boolean result = gestureScanner.onTouchEvent(event);//return the double tap events
return result;
}
