title: Action bar - custom image and text near UP button
body: <p>I have a login screen with two options in my app - "login" and "create account".  I want to implement the following thing, for example, on login screen : </p>
  
  <p><img src="https://i.stack.imgur.com/xD5BW.png" alt="enter image description here"></p>
  
  <p>I've got one activity and another, by tapping on "UP" button i want to return back. I have the following constructor of desired activity:</p>
  
  <pre><code>protected void onCreate(Bundle savedInstanceState)
  {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.activity_bl__login_form_view_controller);
      getActionBar().setDisplayHomeAsUpEnabled(true);
  
      //----------------------added source - no effect-----------------------
  
      getActionBar().setDisplayShowHomeEnabled(true);
      getActionBar().setIcon(R.drawable.circle) ;
      getActionBar().setTitle("A title");
  
  
      //---------------------------------------------------------------------
      setTitle ("Вход") ;
  }
  </code></pre>
  
  <p>And i have UP button. How can i add circle image and some text? All tutorials say, that i can set app icon in AppManifest, but it would change app icon on main screen. And how can i add text to back button? I don't wanna implement any navigation logic or set parent activity for whole app, because it's a login screen, and the main menu with the navigation logic will be shown only after authorization. Thanks in advance!</p>
