Can't handle both click and touch events simultaneously
I am trying to handle touch events and click events on a button. I do the following:
button.setOnClickListener(clickListener);
button.setOnTouchListener(touchListener);
When any one listener is registered things work fine but when I try to use them both only the touch events are fired. Any workaround? What am I doing wrong?
Answer
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.
