I have a question about Material Design.

Hello.

https://material.google.com/motion/transforming-material.html#

What I want to implement is correctangle transforming in this part.

This is the Symmetric transformation part.

I want to implement something that naturally expands when I click on a widget.

I wonder if basic support is available in the design support library or if it needs to be implemented.

Expanding both width and height at the same time can be implemented simply using the ScaleAnimation class. Test by putting the code below in the click listener of a specific view.

ScaleAnimation scaleAnimation = new ScaleAnimation(1f, 2f, 1f, 2f, Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF, 0.5f);
scaleAnimation.setDuration(300);
scaleAnimation.setFillAfter(true);
view.startAnimation(scaleAnimation);
