title: Bottom Align Floating Action Button
body: <p>I want to align to bottom right my FAB.</p>
  
  <ol>
  <li>I tried with <code>android:gravity="bottom|right"</code></li>
  <li>When I try <code>android:layout_alignParentBottom="true</code>" <code>FAB</code> disappears</li>
  <li>When I try <code>android:layout_alignBottom="@id/lista_tiendas"</code> <code>FAB</code> disappears</li>
  </ol>
  
  <p>It doesn't seem complicated but I just can't accomplish it</p>
  
  <p>Any Ideas?</p>
