BaseCardView

public class BaseCardView
extends FrameLayout

java.lang.Object
   ↳ android.view.View
     ↳ android.view.ViewGroup
       ↳ android.widget.FrameLayout
         ↳ androidx.leanback.widget.BaseCardView


A card style layout that responds to certain state changes. It arranges its children in a vertical column, with different regions becoming visible at different times.

A BaseCardView will draw its children based on its type, the region visibilities of the child types, and the state of the widget. A child may be marked as belonging to one of three regions: main, info, or extra. The main region is always visible, while the info and extra regions can be set to display based on the activated or selected state of the View. The card states are set by calling setActivated and setSelected.

See BaseCardView.LayoutParams for layout attributes.
