When my view is in pressed state and the location of a touch event leaves the view, I want the view to get notified. I also want to get notified when the touch location re-enters my view whilst still in pressed state.
My view extends View
, and currently implements this method:
public boolean onTouchEvent(MotionEvent event) {
boolean result = gestureDetector.onTouchEvent(event);
if (!result) {
if (event.getAction() == MotionEvent.ACTION_UP) {
animate().scaleX(1).scaleY(1).setDuration(100).start();
performClick();
}
}
return result;
}
gestureDetector
refers to an instance of this class:
class GestureListener extends GestureDetector.SimpleOnGestureListener {
public boolean onDown(MotionEvent e) {
animate().scaleX(0.9f).scaleY(0.9f).setDuration(100).start();
return true;
}
}
This works just fine, but when a touch is pressed down and released outside of my view, MotionEvent.ACTION_UP
still gets fired (and thus performClick()
too), which is not the behaviour I'm looking for. I have tried many other actions in MotionEvent
, but nothing does this.
Any ideas?
Change your if statement to include the dimensions of the button
boolean inX == event.getX() >= myButton.getX() && event.getX() <= myButton.getX()+myButton.getWidth();
boolean inY == event.getY() >= myButton.getY() && event.getY() <= myButton.getY()+myButton.getWidth();
if (event.getAction() == MotionEvent.ACTION_UP && inX && inY) {
// do cool stuff
