title: Action Bar shows up empty in Android app
body: <p>I want to put an action bar with a menu button into a single android activity. I've put this in my activity XML:</p>
  
  <pre><code>&lt;android.support.v7.widget.Toolbar
          android:id="@+id/my_toolbar"
          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>I've put this in my JAVA file:</p>
  
  <pre><code>@Override
      public boolean onCreateOptionsMenu(Menu menu) {
          MenuInflater inflater = getMenuInflater();
          inflater.inflate(R.menu.chat_menu, menu);
          return true;
      }
      @Override
      public boolean onOptionsItemSelected(MenuItem item) {
          // Handle item selection
          switch (item.getItemId()) {
              case R.id.view_profile:
                  finish();
                  return true;
              case R.id.report_match:
                  finish();
                  return true;
              case R.id.add_match:
                  finish();
                  return true;
              case R.id.unmatch:
                  finish();
                  return true;
  
  
              default:
                  return super.onOptionsItemSelected(item);
          }
      }
  </code></pre>
  
  <p>And I've put this in the menu XML</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;menu xmlns:tools="http://schemas.android.com/tools"
      xmlns:android="http://schemas.android.com/apk/res/android"&gt;
      &lt;item android:id="@+id/title"
          android:title="@string/options"
          android:showAsAction="never"
          tools:ignore="AppCompatResource" /&gt;
      &lt;item android:id="@+id/view_profile"
          android:title="@string/view_profile" /&gt;
      &lt;item android:id="@+id/report_match"
          android:title="@string/report_match" /&gt;
      &lt;item android:id="@+id/add_match"
          android:title="@string/add_match" /&gt;
      &lt;item android:id="@+id/unmatch"
          android:title="@string/unmatch" /&gt;
  &lt;/menu&gt;
  </code></pre>
  
  <p>Currently the action bar shows up empty when I launch the app (<a href="http://i.stack.imgur.com/cS5dt.png" rel="nofollow">IMAGE</a>)
  Which is strange because when I edit the menu XML the preview shows it the way I want it to (<a href="http://i.stack.imgur.com/J7Nr5.png" rel="nofollow">IMAGE</a>). Thanks in advance!</p>
