To create this effect you will need to use AnimationSet, And add to it two animations, one animation would be resizing animation, basically changing the size of the view, the other animation would be a fading animation basically changing the alpha level of this view.

obviously they would be applied to another view and not the icon view.

Code sample:

Animation fadeOut = new AlphaAnimation(1, 0);
fadeOut.setDuration(1000);
 
AnimationSet animation = new AnimationSet(true);
animation.addAnimation(sizingAnimation);
animation.addAnimation(fadeOut);
this.setAnimation(animation);

EDITED (15/09/2020):

Resizing Animation:

 private Animation getResizeAnimation(Context aContext, boolean enlarge) {
    Animation resizeAnimation;
    if (enlarge) {
        resizeAnimation = AnimationUtils.loadAnimation(aContext, R.anim.scale_up_card);
    } else {
        resizeAnimation = AnimationUtils.loadAnimation(aContext, R.anim.scale_down_card);
    }
    resizeAnimation.setFillAfter(true);
    return resizeAnimation;
}

Where scale_up_card is:

<?xml version="1.0" encoding="utf-8"?>
<set
xmlns:android="http://schemas.android.com/apk/res/android">
<scale android:fromXScale="1.0"
       android:fromYScale="1.0"
       android:toXScale="1.03"
       android:toYScale="1.03"
       android:pivotX="50%"
       android:pivotY="10%"
       android:duration="100">
</scale>
</set>

And scale_down_card:

<?xml version="1.0" encoding="utf-8"?>
<set
xmlns:android="http://schemas.android.com/apk/res/android">
<scale android:fromXScale="1.03"
       android:fromYScale="1.03"
       android:toXScale="1.0"
       android:toYScale="1.0"
       android:pivotX="50%"
       android:pivotY="10%"
       android:duration="100">
</scale>
</set>

Obviously, for you case maybe the needed animations are different.
