Class Overview

Drawable containing a set of Drawable keyframes where the currently displayed keyframe is chosen based on the current state set. Animations between keyframes may optionally be defined using transition elements.

This drawable can be defined in an XML file with the <animated-selector> element. Each keyframe Drawable is defined in a nested <item> element. Transitions are defined in a nested <transition> element.

android:state_activated

State value for StateListDrawable, set when a view or its parent has been "activated" meaning the user has currently marked it as being of interest. This is an alternative representation of state_checked for when the state should be propagated down the view hierarchy.

Must be a boolean value, either "true" or "false".
