Making onTouchEvent play nice with OnItemClickListener

问题

I have implemented a custom TextView class so that I can handle touch and touch release events for TextViews that exist in a GridView. I got that to work well. However, I also had set up OnItemClickListener for the GridView so I can handle that event and run code in the main fragment - on click wouldn't be appropriate to handle in the custom TextView class itself. But now that I have implemented both of those they are conflicting and the event to release the touch is not being triggered now.

How do I allow these gesture events to both be triggered - onTouchEvent in a custom class and OnItemClickListener in the GridView, without losing some of the action events?

gridView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
            //handle click
        }
});

In the custom TextView class:

@Override
public boolean onTouchEvent(MotionEvent event) {
    //handle touch and release events only
    if (event.getAction() == MotionEvent.ACTION_DOWN) { 
        //handle touch down
    }
    else if (event.getAction() == MotionEvent.ACTION_UP
            || event.getAction() == MotionEvent.ACTION_MOVE
            || event.getAction() == MotionEvent.ACTION_CANCEL
            || event.getAction() == MotionEvent.ACTION_OUTSIDE
            || event.getAction() == MotionEvent.ACTION_SCROLL) {
        //handle touch release
    }

    return super.onTouchEvent(event);
}

With this code, when I tap and release a TextView, the touch down code is run, the OnItemClickListener is called in the GridView, but onTouchEvent is not called again so the touch release event is not handled.

If I change onTouchEvent to the following, the touch and touch release is properly handled but OnItemClickListener is not called:

    super.onTouchEvent(event);

    if (event.getAction() == MotionEvent.ACTION_DOWN) {
        //handle touch down
        return true;
    } else if (event.getAction() == MotionEvent.ACTION_UP
            || event.getAction() == MotionEvent.ACTION_CANCEL
            || event.getAction() == MotionEvent.ACTION_OUTSIDE
            || event.getAction() == MotionEvent.ACTION_SCROLL) {
        //handle touch release
        return false;
    }

    return true;
