Apply one animation to multiple views at the same time

Question

So Id like to rotate a handful of views all at the same time, all using the same rotation specs. The issue is that for some reason the rotation acts differently for the sec

Answer 1

I was able to do this in Kotlin by programmatically creating one AnimatorSet.
1. Create an ArrayList of the views you want to animate

 var viewList = arrayListOf(view1,view2,view3)

2. Loop through the ArrayList and create a growing AnimatorSet

var ix = 0
var anim = AnimatorSet()
var viewList = arrayListOf(view1,view2,view3)
        viewList.forEach{
        // Initiate the animator set with one ObjectAnimator
            if(ix == 0){
                anim = AnimatorSet().apply {
                    play(ObjectAnimator.ofFloat(it, "rotation", 0F, 360F))
                }
            }
        // Add one ObjectAnimator at a time to the growing AnimatorSet
            else{
                var currentAnim = ObjectAnimator.ofFloat(it,"rotation",0F,360F)
                anim = AnimatorSet().apply {
                    play(anim).with(currentAnim)
                }
            }
            ix++
        }

3. Start the animation

button.setOnClickListener {
            AnimatorSet().apply {
                play(anim)
                start()
            }

Answer 2

So I guess this just isn't possible, so I created a helper method to just apply the same animation to a list of views:

public void doRotations(ArrayList<View> views, int start, int end, int xprop, float xscale, int yprop, float yscale, int duration, Boolean fillAfter){

    for(int i = 0; i < views.size(); i++){
        RotateAnimation temp = new RotateAnimation(start, end, xprop, xscale, yprop, yscale);
        temp.setDuration(duration);
        temp.setFillAfter(fillAfter);
        views.get(i).startAnimation(temp);
    }
}

Definitely a hack, but I guess thats all I'm able to do right now

Do it like this:

ObjectAnimator anim = ObjectAnimator.ofFloat(view, "y", 100f);
arrayListObjectAnimators.add(anim);

ObjectAnimator anim1 = ObjectAnimator.ofFloat(view, "x", 0f);
arrayListObjectAnimators.add(anim1);

ObjectAnimator[] objectAnimators = arrayListObjectAnimators.toArray(new ObjectAnimator[arrayListObjectAnimators.size()]);
AnimatorSet animSetXY = new AnimatorSet();
animSetXY.playTogether(objectAnimators);
animSetXY.duration(1000);
animSetXY.start();
