Customize Touch Feedback
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.
