Action bar - custom image and text near UP button

Question

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 :

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:

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") ;
}

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!

Answer 1

setTitle will set the title and setIcon will set the icon to the ActionBar.

getActionBar().setTitle("Your Title");
getActionBar().setDisplayShowHomeEnabled(true);
getActionBar().setHomeButtonEnabled(true);
getActionBar().setDisplayHomeAsUpEnabled(true);
getActionBar().setIcon(R.drawable.youricon);
