title: Android RelativeLayout issue
body: <p>I've got a RelativeLayout with two nested RelativeLayouts. I want first RL to stay on top and second to be scrollable, but this does not work.</p>
  
  <pre><code>&lt;RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"&gt;
    &lt;RelativeLayout
      android:id="@+id/relativeTop"
      android:layout_width="fill_parent"
      android:layout_height="wrap_content"&gt;
      &lt;!--Buttons--&gt;
    &lt;/RelativeLayout&gt;
    &lt;ScrollView
      android:layout_width="fill_parent"
      android:layout_height="wrap_content"&gt;
      &lt;RelativeLayout
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"&gt;
        &lt;!--Lots of nested RelatiLayouts with Views--&gt;
      &lt;/RelativeLayout&gt; 
    &lt;/ScrollView&gt;
  &lt;/RelativeLayout&gt;
  </code></pre>
