title: Actionbar shows dropdown when only one item in the menu
body: <p>Im using app compat theme in my app, and in the actionbar I have a menu with one item that should be shown as an icon - but instead I get menu button like this</p>
  
  <p><img src="https://i.stack.imgur.com/K2ZsT.png" alt="enter image description here"></p>
  
  <p>Here is my code of the menu xml:</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/action_play"
          android:icon="@drawable/play"
          android:orderInCategory="100"
          android:showAsAction="always"/&gt;
  
  &lt;/menu&gt;
  </code></pre>
  
  <p>And here is the code on how I initialize the actionbar:</p>
  
  <pre><code>getSupportActionBar().setHomeButtonEnabled(true);
          getSupportActionBar().setTitle(title);
          getSupportActionBar().setDisplayHomeAsUpEnabled(true);
          getSupportActionBar().setDisplayShowHomeEnabled(false);
  </code></pre>
  
  <p>and show the menu:</p>
  
  <pre><code>@Override
      public boolean onCreateOptionsMenu(Menu menu) {
          MenuInflater inflater = getMenuInflater();
          inflater.inflate(R.menu.names, menu);
          playStop = menu.findItem(R.id.action_play);
          return true;
      }
  </code></pre>
  
  <p>So can someone help me to display the menu item as it should?</p>
  
  <p>Thanks</p>
