title: android title won't show in toolbar
body: <p>I have an xml that I use with so many activities with fragments file but my problem is that I can't display the text I want in the toolbar, I use that xml that way because I have a navigation drawer and I needed to handle somethings so I had to do it that way.</p>
  
  <p>my xml:</p>
  
  <pre><code>&lt;RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
      xmlns:tools="http://schemas.android.com/tools"
      android:id="@+id/frame_container"
      android:layout_width="match_parent"
      android:layout_height="match_parent"
      tools:context=".StatusActivity"
      android:orientation="vertical" &gt;
  
      &lt;android.support.v7.widget.Toolbar
          android:id="@+id/toolbar"
          style="@style/ToolBarStyle"
          android:layout_width="match_parent"
          android:layout_height="wrap_content"
          android:background="?attr/colorPrimary"
          android:minHeight="@dimen/abc_action_bar_default_height_material" /&gt;
  
  &lt;/RelativeLayout&gt;
  </code></pre>
  
  <p>One of my activities:</p>
  
  <pre><code>public class GroupChatActivity extends ActionBarActivity {
  
      @Override
      public void onCreate(Bundle savedInstanceState) {
  
          super.onCreate(savedInstanceState);
          setContentView(R.layout.activity_base_layout);
  
          Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
           setSupportActionBar(toolbar);
           getSupportActionBar().setDisplayShowHomeEnabled(true);
  
           ActionBar actionBar = getSupportActionBar();
           actionBar.setTitle("Groups history");
  
          Aniways.init(this);
  
          if(savedInstanceState == null)
          {
              FragmentManager manager = getSupportFragmentManager();
  
              Fragment fragment = GroupChatFragment.newInstance(getIntent().getIntExtra("uid", 0));
              manager.beginTransaction().add(R.id.frame_container, fragment).commit();
          }
      }
  }
  </code></pre>
  
  <p>as you can see I try to set title to the action bar but it doesn't work.</p>
