If you want the ripple to extend past the boundary of the view, then you can instead use ?attr/selectableItemBackgroundBorderless. If you donвЂ™t like the default grey, you can specify what color you want android:colorControlHighlight to be in your theme. Using ?android:colorControlHighlight will give the ripple the same color as the built-in ripples in your app. You can add this feedback for your own drawables and for custom buttons by simply wrapping them in a ripple element:

So the default button background is not going to work for you here. If you have a custom button with selected state, your text color changes depending on the state, etc. Usually youвЂ™ll have a pressed and normal version of assets like this: Most buttons are made with several drawables. setBackgroundResource ( backgroundResource ) obtainStyledAttributes ( attrs ) int backgroundResource = typedArray. In code: int attrs = new int TypedArray typedArray = getActivity (). In general, ripple effect for regular buttons will work by default in API 21, and for other touchable views it can be achieved by specifying android:background='?android:attr/selectableItemBackground'> Note that the ripples will only show up on devices running Lollipop, and will fall back to a static highlight on previous versions. 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. When the ripple animation ends, the view returns to its original appearance. 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.

For example, the following sequence of screenshots illustrates the ripple effect in a button during touch animation: The ripple effect can be configured to end at the bounds of the view or extend beyond the bounds of the view.

Ripple animation is implemented by the new RippleDrawable class. For example, buttons now display a ripple effect when they are touched - this is the default touch feedback animation in Android 5.0. Touch feedback in material design provides an instantaneous visual confirmation at the point of contact when users interact fwith UI elements. Ripple touch effect was introduced with material design in Android 5.0 (API level 21).
