CardFragment

public class CardFragment
extends Fragment

java.lang.Object
   ↳ android.app.Fragment
     ↳ android.support.wearable.view.CardFragment


This class is deprecated.
starting with Android Wear 2.0 it is no longer encouraged to use cards for apps' UI. If you are looking to implement vertical paging pattern, consider using the SnapHelper and a RecyclerView instead.

Presents content within an expandable, vertically scrollable card. The default layout contains a title, icon and text, but may be replaced by overriding onCreateContentView(LayoutInflater, ViewGroup, Bundle).

Additional methods are supplied for adjusting the appearance of the card, including whether content should clip or appear as expandable, and the maximum height of the card.
