Material Design Android Ripple Effect

Here’s on how to add a neat Ripple effect for your UI components. I’ll take a button for this. Create new folder res/drawable-v21 and create a new XML ripple.xml

Add this to your button layout: android:background="@drawable/ripple" Note that the Android ripple effect only works on Lollipop versions and above. So you might want to use a normal color selector for previous versions as a fallback. So set your background to be a regular color selector, and for Lollipop handle it like this in your Activity.java

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
             button.setBackground(getDrawable(R.drawable.ripple));
}
