Getting Started with CardView

CardView is a member of the Android Support Library, and provides a layout for cards.

To add CardView to your project, add the following line to your build.gradle dependencies.

compile 'com.android.support:cardview-v7:25.1.1'

A number of the latest version may be found here

In your layout you can then add the following to get a card.

<android.support.v7.widget.CardView
        xmlns:card_view="http://schemas.android.com/apk/res-auto"
        android:layout_width="match_parent"
        android:layout_height="wrap_content">

        <!-- one child layout containing other layouts or views -->     

</android.support.v7.widget.CardView>

You can then add other layouts inside this and they will be encompassed in a card.

Also, CardView can be populated with any UI element and manipulated from code.
