onTouch, onLongClick together in Android

Question

I'm adding ImageViews to parent layout dynamically and performing zoom in/out operations with onTouch on the added image.

I want to remove the added view with an onLongPress of it.

img.setOnLongClickListener(longClickAction);
img.setOnTouchListener(touchAction); 
 

onLongPress:

OnLongClickListener longClickAction = new OnLongClickListener() {
    @Override
    public boolean onLongClick(View v) {
        parentLayout.removeView((ImageView)v);
        return false;
    }
};

onTouch:

OnTouchListener touchAction = new OnTouchListener() {
    @Override
    public boolean onTouch(View v, MotionEvent event) {
        ImageView i = (ImageView)v;

        // Perform zoom operation onTouch of ImageView
        zoom(i, event);
        return true; 
    }
};

Why do only the onTouch events work?

How can I get them both to work?

What should I do to remove the added view?

Answer 1

onTouch is always called for your view since this is the initial state of dispatching the events to the view. When you long press your view this still calls onTouch first and since you return true in onTouch(which means that you've consumed this event and it should not be further dispatched) you won't get onLongPress called. What will do the trick is returning false in onTouch
