Add Ripple Background in Button with Background Colours in Android | Animation

Ripple touch effect was introduced with material design in Android 5.0 (API level 21).

Touch feedback in material design provides an instantaneous visual confirmation at the point of contact when users interact fwith UI elements. For example, buttons now display a ripple effect when they are touched - this is the default touch feedback animation in Android 5.0. Ripple animation is implemented by the new RippleDrawable class. The ripple effect can be configured to end at the bounds of the view or extend beyond the bounds of the view. For example, the following sequence of screenshots illustrates the ripple effect in a button during touch animation:

Initial touch contact with the button occurs in the first image on the left, while the remaining sequence (from left to right) illustrates how the ripple effect spreads out to the edge of the button. When the ripple animation ends, the view returns to its original appearance. The default ripple animation takes place in a fraction of a second, but the length of the animation can be customized for longer or shorter lengths of time.

Note that the ripples will only show up on devices running Lollipop, and will fall back to a static highlight on previous versions.
