title: Menu not showing on Toolbar
body: <p>I followed this guide (<a href="https://developer.android.com/training/appbar/setting-up.html" rel="nofollow noreferrer">https://developer.android.com/training/appbar/setting-up.html</a>) to set up an action bar for my activity but I am unable to get the menu button (3 horizontal lines top right) to show.</p>
  
  <p>I am extending AppCompatActivity and using a GoogleMap Fragment which correctly shows below my action bar.</p>
  
  <p>In the manifest I have set:</p>
  
  <pre><code>android:theme="@style/Theme.AppCompat.Light.NoActionBar" 
  </code></pre>
  
  <p>as instructed by the guide.</p>
  
  <p><strong>Menu resource file</strong></p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;menu
      xmlns:android="http://schemas.android.com/apk/res/android"
      xmlns:app="http://schemas.android.com/apk/res-auto" &gt;
  
      &lt;item
          android:id="@+id/action_settings"
          android:title="@string/action_settings"
          app:showAsAction="always" /&gt;
  
  
  &lt;/menu&gt;
  </code></pre>
  
  <p><strong>Toolbar xml</strong></p>
  
  <pre><code>&lt;android.support.v7.widget.Toolbar
      android:id="@+id/my_toolbar"
      android:title="@string/toolbar_title"
      android:layout_width="match_parent"
      android:layout_height="?attr/actionBarSize"
      android:background="?attr/colorPrimary"
      android:elevation="4dp"
      android:theme="@style/ThemeOverlay.AppCompat.ActionBar"
      app:popupTheme="@style/ThemeOverlay.AppCompat.Light" /&gt;
  </code></pre>
  
  <p><strong>onCreate</strong></p>
  
  <pre><code>@Override
  protected void onCreate(Bundle savedInstanceState) {
      Log.i(LOG_TAG, "onCreate");
      super.onCreate(savedInstanceState);
      setContentView(R.layout.activity_maps);
  
      //Toolbar
      Toolbar myToolbar = (Toolbar) findViewById(R.id.my_toolbar);
      myToolbar.inflateMenu(R.menu.menu_activity_maps);
      setSupportActionBar(myToolbar);
      getSupportActionBar().setTitle("yoyo");
  
      //Obtain the SupportMapFragment and call onMapReady when it is ready to be used
      SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager()
              .findFragmentById(R.id.map);
      mapFragment.getMapAsync(this);
  }
  </code></pre>
  
  <p>How do I get the menu to show?</p>
