Object appears at start (press) the Onlongclicklistener event and disappears at end (drop)

Question

I’m thinking of a way to make a view with the attribute visibility: gone be visible when you click long click on the screen and disappear as soon as you drop, similar to and done with Instagram. Someone has an idea how to do?

Answer 1

You can do this way using the event setOnTouchListener, within this event, you will come across the method onTouch that will rescue the action that the user is using, the ACTION_DOWN, for when the user is holding the button and ACTION_UP, for when the user releases the button:

my_btn.setOnTouchListener(new View.OnTouchListener() {
        @Override
        public boolean onTouch(View v, MotionEvent event) {
            if (event.getAction() == MotionEvent.ACTION_DOWN) {
                // Abra sua View

            } else if (event.getAction() == MotionEvent.ACTION_UP) {
               // Feche sua View

            }
            return false;
        }
    });
