How to make imageView on card fullscreen when single tapped?

[ctoto93]

Here is my implementation to see imageView on card in fullscreen by double tapping. However, I need it to be single tap. My problem is, on MotionEvent.ACTION_DOWN, it need to be return false so that the card can be swiped, but ACTION_UP will be never called since it is not consumed in the event ACTION_DOWN.

    profilePicture.setOnTouchListener(new View.OnTouchListener() {
        long timestamp = 0;

        @Override
        public boolean onTouch(View v, MotionEvent event) {

            if (event.getActionMasked() == MotionEvent.ACTION_DOWN) {
                long now = System.currentTimeMillis();
                long diff = now - timestamp;
                if (diff < 500) {
                    Log.d("Gesture", "double tap");
                    Intent i = new Intent(context, FullPhotoActivity.class);
                    i.putExtra("deviceID", userToShow.getDeviceID());
                    context.startActivity(i);
                    return true;
                } else {
                    timestamp = now;
                }

            }
            return false;

        }


    });

Don't use the OnTouchListener but use the OnClickListener instead. Since the touch events are consumed in the listeners, that will disable the swipe in the current implementation of the library when the swipe is started on the picture.

Previously, I used onClickListener. When image is pressed (not realesed yet), the card is not moved. When it is released, the onclicklistener invoked

That's indeed the limitation of using the OnClickListener, you'll have to delegate the touch events to the child views which will be quite a challenge.

So what would you suggest? I need it to be singe rather than double tapped, just like Tinder does. Thanks before :'D

You can edit the FlingCardListener to handle the touch events as clicks if there is little to no movement between the UP and DOWN event. I've had this problem too though, I'm planning to write this myself somewhere in the future.
