MaterialCardView

public class MaterialCardView
extends CardView implements Checkable, Shapeable

java.lang.Object
   ↳ android.view.View
     ↳ android.view.ViewGroup
       ↳ android.widget.FrameLayout
         ↳ androidx.cardview.widget.CardView
           ↳ com.google.android.material.card.MaterialCardView


Provides a Material card.

This class supplies Material styles for the card in the constructor. The widget will display the correct default Material styles without the use of a style flag.

Stroke width can be set using the strokeWidth attribute. Set the stroke color using the strokeColor attribute. Without a strokeColor, the card will not render a stroked border, regardless of the strokeWidth value.

Cards implement Checkable, a default way to switch to android:checked_state is not provided. Clients have to call setChecked(boolean). This shows the app:checkedIcon and changes the overlay color.

Cards also have a custom state meant to be used when a card is draggable app:dragged_state. It's used by calling setDragged(boolean). This changes the overlay color and elevates the card to convey motion.

Note: The actual view hierarchy present under MaterialCardView is NOT guaranteed to match the view hierarchy as written in XML. As a result, calls to getParent() on children of the MaterialCardView, will not return the MaterialCardView itself, but rather an intermediate View. If you need to access a MaterialCardView directly, set an android:id and use View.findViewById(int).
