Can't handle both click and touch events simultaneously


Its a little tricky.

If you set onTouchListener you need to return true in ACTION_DOWN, to tell the system that I have consumed the event and it won't trickle down to other listeners.

But then OnClickListener won't be fired.

So you might think, I will just do my thing there and return false so I can receive clicks too.If you do so, it will work, but you won't be subscribed to other upcoming touch events (ACTION_MOVE, ACTION_UP)Therefore, the only option is to return true there, but then you won't receive any click events as we said previously.

So you need to perform the click manually in the ACTION_UP with view.performClick()

This will work.


There is a subtle, yet very important difference between the ClickListener and the TouchListener. The TouchListener is executed before the view can respond to the event. The ClickListener will receive its event only after the view has handled it.

So when you touch your screen, the TouchListener is executed first and when you return true for your event, the ClickListener will never get it. But if you press the trackball of your device, the ClickListener should be fired because the TouchListener will not respond to it.


Thanks to @urSus for great answer
But in that case every touch will perform click, Even ACTION_MOVE
Assuming you want to separate move event and click event you can use a little trick
define a boolean field and use like this:

 @Override        public boolean onTouch(View view, MotionEvent motionEvent)        {            switch (motionEvent.getAction() & MotionEvent.ACTION_MASK)            {                case MotionEvent.ACTION_DOWN:                    shouldClick = true;                    .                    .                    break;                case MotionEvent.ACTION_UP:                    if (shouldClick)                        view.performClick();                    break;                case MotionEvent.ACTION_POINTER_DOWN:                    break;                case MotionEvent.ACTION_POINTER_UP:                    break;                case MotionEvent.ACTION_MOVE:                    //Do your stuff                    shouldClick = false;                    break;            }            rootLayout.invalidate();            return true;        }
