Just simply add this code to your Card View in xml file!

    card_view:cardUseCompatPadding="true"

You have to import card_view with Alt+Enter ! And code below will be import in top !.

You'll see elevation is working on android 5 or 5+ .

Answer 5

To make it both compatible above or below api 21, you need to specify app:cardUseCompatPadding="true" in your support CardView.

<android.support.v7.widget.CardView
        app:cardElevation="4dp"
        app:cardUseCompatPadding="true"
        app:cardMaxElevation="6dp"
        android:layout_width="match_parent"
        android:layout_height="wrap_content">
</android.support.v7.widget.CardView>
