Android, is there an OnRelease functions?

Say I want a dialog to .show() when the user Touches a certain element and .hide() once he releases it.

I found how to make the O开发者_如何学JAVAnTouchListener. But is there any sort of OnReleaseListener?

Thanks!

Thats actually included in the OnTouchListener. It gives you a MotionEvent on the callback, use MotionEvent.getAction() and check if it equals MotionEvent.ACTION_UP. That means the user released the finger.

Equally you can check for ACTION_DOWN to differentiate the two.

onTouchListener returns you a TouchEvent object, which contains the current touch action, that can be retrieved by calling event.getAction(). There are some actions, one of them are ACTION_DOWN and ACTION_UP: first tells you, that the user has touched some view, and second tells you that user has taken his finger off a view. Means onRelease will be onTouch with the ACTION_UP action. Hope this helps.
