title: Android ActionBar custom action view tool-tip
body: <p>I have an app that is using a SupportActionBar. I am usin a custom view for an action. </p>
  
  <p>The thing is, that default actions do display a tool-tip when i long press, but my custom action does not.</p>
  
  <p>So here is the default action (as you can see, there is a tool-tip):
  <img src="https://i.stack.imgur.com/d6Koz.png" alt="Action item with tool-tip"></p>
  
  <p>And here is my custom action (no tool-tip for this one :/):
  <img src="https://i.stack.imgur.com/ThIWW.png" alt="enter image description here"></p>
  
  <p>The xml for these 2:</p>
  
  <pre><code>    &lt;menu
          xmlns:android="http://schemas.android.com/apk/res/android"
          xmlns:custom="http://schemas.android.com/apk/res-auto"&gt;
  
          &lt;item
              android:visible="false"
              android:title="Clear history"
              android:id="@+id/action_clear_history"
              custom:showAsAction="always"
              android:icon="@drawable/ic_action_trash" /&gt;
          &lt;item
              android:title="Open chat"
              android:id="@+id/action_chat"
              custom:showAsAction="always"
              custom:actionLayout="@layout/ab_chat" /&gt;
      &lt;/menu&gt;
  </code></pre>
  
  <p>Can someone help?</p>
