title: ListFragment FloatingActionButton is at wrong position
body: <p>In my app I have a <code>FloatingActionButton</code> in a <code>ListFragment</code>.</p>
  
  <p>Here is the layout of the <code>ListFragment</code>:</p>
  
  <pre><code>&lt;android.support.design.widget.CoordinatorLayout
      android:id="@+id/main_content"
      xmlns:android="http://schemas.android.com/apk/res/android"
      xmlns:app="http://schemas.android.com/apk/res-auto"
      android:layout_width="match_parent"
      android:layout_height="match_parent"&gt;
  
      &lt;include layout="@android:layout/list_content"/&gt;
  
      &lt;ListView
          android:id="@id/android:list"
          android:layout_width="match_parent"
          android:layout_height="match_parent" /&gt;
  
      &lt;TextView
          android:id="@id/android:empty"
          android:layout_width="match_parent"
          android:layout_height="match_parent"
          android:text="@string/no_contacts"/&gt;
  
      &lt;android.support.design.widget.FloatingActionButton
          android:id="@+id/fab"
          android:layout_width="wrap_content"
          android:layout_height="wrap_content"
          android:layout_gravity="bottom|end"
          android:layout_margin="16dp"
          android:src="@drawable/ic_add"
          app:layout_anchor="@id/android:list"
          app:layout_anchorGravity="bottom|end"
          android:layout_alignParentEnd="true"/&gt;
  &lt;/android.support.design.widget.CoordinatorLayout&gt;
  </code></pre>
  
  <p>In Android Studio the FAB is at the <code>bottom-right</code> position but when I run the app it's at the <code>top-left</code>.</p>
