onTouch Event on Layout only registering one Touch per Click

I have the following Problem: I created a new Class extending a ConstraintLayout and I am overriding the onTouchEvent function to animate the Layout.

@Override
public boolean onTouchEvent(MotionEvent event) {

switch(event.getAction()) {
case MotionEvent.ACTION_DOWN:
ObjectAnimator scaleDownX = ObjectAnimator.ofFloat(this, "scaleX", 0.85f);
ObjectAnimator scaleDownY = ObjectAnimator.ofFloat(this, "scaleY", 0.85f);
scaleDownX.setDuration(100);
scaleDownY.setDuration(100);

AnimatorSet scaleDown = new AnimatorSet();
scaleDown.play(scaleDownX).with(scaleDownY);

scaleDown.start();
break;

case MotionEvent.ACTION_CANCEL:
Log.d("arne", "CANCEL");
// Beide Cases lösen das Event aus
// ACTION_CANCEL minimiert den Button auch, wenn man den Knopf nicht loslässt, sondern weg wischt
case MotionEvent.ACTION_UP:
ObjectAnimator scaleUpX = ObjectAnimator.ofFloat(this, "scaleX", 1f);
ObjectAnimator scaleUpY = ObjectAnimator.ofFloat(this, "scaleY", 1f);
scaleUpX.setDuration(100);
scaleUpY.setDuration(100);

AnimatorSet scaleUp = new AnimatorSet();
scaleUp.play(scaleUpX).with(scaleUpY);

scaleUp.start();
break;
}

return super.onTouchEvent(event);
}


This works flawlessly for Buttons and if I keep the button pressed down the Event fires multiple times in one Second.

But on an ConstraintLayout it fires only one time, just like the onClick Event.

This is a bit weired in my understanding.

Do you have a solution for this Problem?

Okay, I finally found the solution.

You just need to set your Layout clickable.

android:clickable="true"
