title: Space Between CardView
body: <p>I need to add space between <code>CardView</code>.</p>
  
  <p>I tried to use the <code>card_view:cardUseCompatPadding</code> and it doesn't work. Any help? </p>
  
  <pre><code>&lt;RelativeLayout
      android:layout_width="match_parent"
      android:layout_height="wrap_content"&gt;
  
      &lt;android.support.v7.widget.CardView
          android:id="@+id/all_restaurant_card_view"
          android:layout_width="wrap_content"
          android:layout_height="120dp"
  
          xmlns:card_view="http://schemas.android.com/apk/res-auto"
          card_view:cardPreventCornerOverlap="true"
          card_view:cardUseCompatPadding="true"&gt;
  </code></pre>
