title: Bottom navigation view with custom item (actionLayout)
body: <p>I would like to add a custom item in the new <a href="https://developer.android.com/reference/android/support/design/widget/BottomNavigationView.html" rel="noreferrer">BottomNavigationView </a>.</p>
  
  <p>There are plenty of tutorial of adding a custom view with the normal navigation view but I can't find anything regarding the bottom one.</p>
  
  <p>This is my view</p>
  
  <pre><code>   &lt;android.support.design.widget.BottomNavigationView
          android:id="@+id/navigation_view"
          android:layout_width="match_parent"
          android:layout_height="wrap_content"
          app:menu="@menu/menu_main" /&gt;
  </code></pre>
  
  <p>And this is the menu</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
   &lt;menu xmlns:android="http://schemas.android.com/apk/res/android"&gt;
  
  &lt;item
      android:id="@+id/menu_one"
      android:icon="@drawable/ic_tab_one"
      android:title="one" /&gt;
  &lt;item
      android:id="@+id/menu_two"
      app:actionLayout="@layout/item_action_notification"
      android:title="two" /&gt;
  </code></pre>
  
  <p></p>
  
  <p>As you can see I put <strong>actionLayout</strong> tag as you would do normally, but it is simply not displayed.</p>
  
  <p>Any ideas? Thanks.</p>
