title: View not showing up in relativeLayout
body: <p>I am trying to create a bracket <code>[</code> in a RelativeLayout. The top and bottom lines show. But the left line does not show. Is there something wrong with my code?</p>
  
  <pre><code>   &lt;View
          android:id="@+id/top"
          android:layout_width="20dp"
          android:layout_height="1dp"
          android:layout_alignParentLeft="true"
          android:layout_alignParentTop="true"
          android:background="#000000" /&gt;
  
      &lt;View
          android:id="@+id/left"
          android:layout_width="1dp"
          android:layout_height="match_parent"
          android:layout_alignParentBottom="true"
          android:layout_alignParentLeft="true"
          android:background="#000000" /&gt;
  
      &lt;View
          android:id="@+id/bottom"
          android:layout_width="20dp"
          android:layout_height="1dp"
          android:layout_alignParentBottom="true"
          android:layout_alignParentLeft="true"
          android:background="#000000" /&gt;
  </code></pre>
