android:background=”?selectableItemBackground”
where ?attr/ references to attributes. Attributes are values specified in your apps theme. for more Referencing style attributes.
2. Unbounded Ripple effect, once user click on view then the effect will extends the view's bounds or outside the view's bound.

Unfortunately,these ripples are always grey in color.
To tweak these based on your theme, go to your parent theme and change the colorControlHighlight.
In your app’s main theme:
<item name="colorControlHighlight">#1bff3a</item>
This value will change the color of the default ripple.
Note: On devices below 21, the ripple will turn into normal selectors with the same color you have set.
