title: RelativeLayout - CenterInParent and marginTop
body: <p>I has the following XML:</p>
  
  <pre><code>&lt;RelativeLayout android:id="@+id/cover_box"
      android:layout_width="wrap_content" android:layout_height="wrap_content"&gt;
      &lt;ImageView android:id="@+id/cover"
          android:layout_width="wrap_content" android:layout_height="wrap_content" /&gt;
      &lt;ImageView android:id="@+id/download" android:layout_width="wrap_content"
          android:layout_height="wrap_content" android:src="@drawable/mark_download"
          android:layout_centerInParent="true" android:layout_marginTop="90px" /&gt;
  &lt;/RelativeLayout&gt;
  </code></pre>
  
  <p>But it's look's like the marginTop is being ignored.</p>
