How to fill a view with another with Material Design Animation?

Question

I\'m trying to go around different functionality integrated with Android Material Design but I can\'t to do this type of animation when a view fill another

Answer 1

The solution to do that is pathInterpolator and the name of this effect is Curved Motion.

Animations in material design rely on curves for time interpolation and spatial movement patterns. With Android 5.0 (API level 21) and above, you can define custom timing curves and curved motion patterns for animations.

You can see how to implement it here :
