title: android:layout_marginRight attribute not working on RelativeLayout
body: <p>I have an Inner relative layout with 2 images, and when I set the android:layout_marginRight
  attribute it doesn't do anything.</p>
  
  <p>Here is my code:</p>
  
  <pre><code>&lt;RelativeLayout
      android:id="@+id/location_image_layout"
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      android:layout_alignParentRight="true"
      android:layout_centerVertical="true" &gt;
  
      &lt;ImageView
          android:layout_width="wrap_content"
          android:layout_height="wrap_content"
          android:layout_marginRight="80dp" /&gt;
  
      &lt;ImageView
          android:layout_width="69.33dp"
          android:layout_height="72dp"
          android:background="@drawable/icon"
          android:layout_centerInParent="true" /&gt;
  
  &lt;/RelativeLayout&gt;
  </code></pre>
