title: RecyclerView inside ScrollView is not working
body: <p>I'm trying to implement a layout which contains RecyclerView and ScrollView at the same layout.</p>
  
  <p>Layout template: </p>
  
  <pre><code>&lt;RelativeLayout&gt;
      &lt;ScrollView android:id="@+id/myScrollView"&gt;
         &lt;unrelated data&gt;...&lt;/unrealated data&gt;
  
             &lt;android.support.v7.widget.RecyclerView
                  android:layout_width="match_parent"
                  android:layout_height="wrap_content"
                  android:id="@+id/my_recycler_view"
              /&gt;
      &lt;/ScrollView&gt;
  
  
  &lt;/RelativeLayout&gt;
  </code></pre>
  
  <p>Problems: i can scroll until the last element of <code>ScrollView</code></p>
  
  <p>Things i tried: </p>
  
  <ol>
  <li>card view inside the <code>ScrollView</code> (now <code>ScrollView</code> contains <code>RecyclerView</code>) - can see the card up until the <code>RecyclerView</code></li>
  <li>initial thought was to implement this <code>viewGroup</code> using <code>RecyclerView</code> instead of <code>ScrollView</code> where one of it's views type is the <code>CardView</code> but i got the exact same results as with the <code>ScrollView</code></li>
  </ol>
