title: NavigationView: custom item layout with app:actionLayout how to?
body: <p>according to recent Ian Lake post</p>
  
  <blockquote>
    <p>And if you haven't looked at NavigationView recently, it actually got
    quite an update in version 23.1.0 [1] with the addition of
    app:actionLayout support for custom view support.</p>
  </blockquote>
  
  <p>How can I use <code>app:actionLayout</code> in NavigationView?</p>
  
  <p>Using</p>
  
  <pre><code>&lt;group android:checkableBehavior="single"&gt;
      &lt;item
          android:id="@+id/navigation_drawer_item_1"
          android:icon="@drawable/ic_menu_1"
          android:title="@string/navigation_drawer_item_1"
          app:actionLayout="@layout/menu_test_1"
          /&gt;
      &lt;item
          android:id="@+id/navigation_drawer_item_2"
          android:icon="@drawable/ic_menu_2"
          android:title="@string/navigation_drawer_item_2"
          app:actionLayout="@layout/menu_test_1"
          /&gt;
  &lt;/group&gt;
  </code></pre>
  
  <p>with</p>
  
  <pre><code>&lt;android.support.design.widget.NavigationView android:id="@+id/nav_view"
      android:layout_width="wrap_content"
      android:layout_height="match_parent"
      android:layout_gravity="start"
      android:fitsSystemWindows="true"
      app:headerLayout="@layout/nav_header_main"
      app:menu="@menu/activity_main_drawer"&gt;
  </code></pre>
  
  <p>It doesn't work.
  It shows the actionLayout on the right side of the item.
  Also removing <code>android:icon</code> and <code>android:title</code> seems not working.</p>
  
  <p>How can i fix it?</p>
  
  <p>Thank you
  Regards</p>
