How to detect doubletap on a View? [duplicate]

Answer 1

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;
}
