      Description

      Touch feedback in material design provides an instantaneous visual confirmation at the point of contact when users interact with UI elements. The default touch feedback animations for buttons use the new RippleDrawable class, which transitions between different states with a ripple effect.

      In most cases, you should apply this functionality in your view XML by specifying the view background as:

      ?android:attr/selectableItemBackground for a bounded ripple.
      ?android:attr/selectableItemBackgroundBorderless for a ripple that extends beyond the view. It will be drawn upon, and bounded by, the nearest parent of the view with a non-null background.
      Note: selectableItemBackgroundBorderless is a new attribute introduced in API level 21.

      Alternatively, you can define a RippleDrawable as an XML resource using the ripple element.

      You can assign a color to RippleDrawable objects. To change the default touch feedback color, use the theme's android:colorControlHighlight attribute.

      For more information, see the API reference for the RippleDrawable class.
