ObjectAnimator with scale property makes bg black?

Question

I use ObjectAnimator to scale down a RelativeLayout :

            ObjectAnimator scaleDownX = ObjectAnimator.ofFloat(view, \"scaleX\", 0.5f);
            Obj         


        

Answer 1

It may not be the cleanest solution, but adding animation update listener and invalidating the parent might do the job.

ObjectAnimator scaleDownX = ObjectAnimator.ofFloat(view, "scaleX", 0.5f);
ObjectAnimator scaleDownY = ObjectAnimator.ofFloat(view, "scaleY", 0.5f);
scaleDownX.setDuration(1000);
scaleDownY.setDuration(1000);

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

scaleDownX.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() {
     @Override
     public void onAnimationUpdate(ValueAnimator valueAnimator) {
         View p= (View) v.getParent();
         p.invalidate();
     });
scaleDown.start();
