Handle OnTouch Event inside an Activity
Im Trying to handle an OnTouch Event inside an activity But I am unable to Handle MotionEvent.ACTION_UP Action. here is my code:
boardView.setOnTouchListener(new OnTouchListener() {
@Ov开发者_运维问答erride
public boolean onTouch(View v, MotionEvent event) {
switch (event.getAction())
{
case MotionEvent.ACTION_DOWN:
showToastNotification("ACTION_DOWN");
break;
case MotionEvent.ACTION_MOVE:
break;
case MotionEvent.ACTION_UP:
showToastNotification("ACTION_UP");
break;
}
return false;
}
});
Why Is That?
Thanks in advance

The "onTouch" event has to return "true" istead of "false".
Do you see the "ACTION_DOWN" toast? Is it just the "ACTION_UP" toast which does not show?
Could be (Guess) When ACTION_DOWN happens, the Toast appears and the Activity is not in control of ACTION_UP. Or.. as @C0deAttack said, it might be behind the scenes. Use ACTION_DOWN notification as Toast.short and ACTION_UP as Toast.long .. OR you could use LogCat.
