        CardView
            A FrameLayout with a rounded corner background and shadow.
            CardView uses elevation property on L for shadows and falls back to a custom shadow
            implementation on older platforms.
    -->
    <!--
        android.support.v7.cardview:cardElevation
            Elevation for CardView.
            Must be a dimension value, which is a floating point number appended with a unit such
            as "14.5sp". Available units are: px (pixels), dp (density-independent pixels), sp
            (scaled pixels based on preferred font size), in (inches), mm (millimeters).

            This may also be a reference to a resource (in the form "@[package:]type:name") or
            theme attribute (in the form "?[package:][type:]name") containing a value of this type.

            This is a private symbol.
    -->
    <!--
        android.support.v7.cardview:contentPadding
            Inner padding between the edges of the Card and children of the CardView.
    -->
    <!--
        android.support.v7.cardview:cardBackgroundColor
            Background color for CardView.
            Must be a color value, in the form of "#rgb", "#argb", "#rrggbb", or "#aarrggbb".
            This may also be a reference to a resource (in the form "@[package:]type:name") or
            theme attribute (in the form "?[package:][type:]name") containing a value of this type.
            This is a private symbol.
    -->
    <!--
        android.support.v7.cardview:cardCornerRadius
            Corner radius for CardView.
            Must be a dimension value.
