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 :

enter image description here

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!

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);

What about:

getActionBar().setIcon(R.drawable.circle);

use getActionBar().setIcon(R.drawable.youricon) for setting the icon and getActionBar().setTitle("A title"); for setting the text next to the icon.

  • I've done so, but nothing works. Shall i edit xml styles of action bar? – Nikita Semenov Sep 02 '14 at 08:12
  • You could do it with xml styles, but it should work the way i (and everyone else) wrote. What exactly is not working? – Gumbo Sep 02 '14 at 08:25
  • Only backarrow "<" at left up corner appears, but no icon or text – Nikita Semenov Sep 02 '14 at 08:37
  • @NikitaPronchik maybe the text/icon has the same color as the background? In that case see [this](https://developer.android.com/training/basics/actionbar/styling.html) tutorial on how to change that. – Gumbo Sep 02 '14 at 08:53

For the icon:

getActionBar().setIcon(R.drawable.youricon);

For the title:

getActionBar().setTitle("A title");

you can use custom action bar using your own layout 

actionBar.setDisplayShowHomeEnabled(false);
actionBar.setHomeButtonEnabled(false);
actionBar.setDisplayShowTitleEnabled(false);
actionBar.setDisplayShowCustomEnabled(true);

final ViewGroup actionBarLayout = (ViewGroup)getLayoutInflater().inflate(R.layout.yourXML, null);
actionBarLayout.findViewById(R.id.buttonId).setOnClickListener(this);

actionBar.setCustomView(actionBarLayout);

its work for me. so i hope its work for you.

  • Only backarrow "<" at left up corner appears, but no icon or text – Nikita Semenov Sep 02 '14 at 08:38
  • did you create layout for that ? – Mr. Borad Sep 02 '14 at 08:39
  • Well, i've got auto-generated xml file for this bar in menu folder, but it seems like i can adjust only right - group buttons in tags in it. Isn't it? – Nikita Semenov Sep 02 '14 at 08:42
  • yes is it. you have to create you xml in layout folder. then it will be show as action bar. got it ? – Mr. Borad Sep 02 '14 at 08:44
  • Yep, i've already got the layout for activity in res/layout and for action bar in res/menu. In res/menu, as i've understood a xml-file with settings of action bar is, as in res/layout there is a xml-file for the whole activity exists. According to manual, i must edit res/menu file to add new items to bar in right group. But, it seems, i didn't quite catch, what shall i do with res/layout file to make this case work? – Nikita Semenov Sep 02 '14 at 08:53

The accepted answer serves the problem well. I'm just adding some additional information of using a custom action bar layout. 

getActionBar().setTitle("Your Title");
getActionBar().setDisplayShowHomeEnabled(true);
getActionBar().setHomeButtonEnabled(true);
getActionBar().setDisplayHomeAsUpEnabled(true);
getActionBar().setIcon(R.drawable.youricon);
// You can use setLogo instead like 
// getActionBar().setIcon(R.drawable.youricon);

// In case of support action bar, if its not showing properly, you need to add display options
//getActionBar().setDisplayOptions(actionBar.getDisplayOptions() | ActionBar.DISPLAY_SHOW_CUSTOM);

Now here's a code segment describing how to use a custom layout in android actionbar.

// Make a layout named 'custom_actionbar' and simply add elements you want to show in your actionbar.
final ViewGroup actionBarLayout = (ViewGroup) getLayoutInflater()
                .inflate(R.layout.custom_actionbar, null);
// Now for support action bar, get the action bar 
actionBar = getSupportActionBar();

// Set necessary attributes
actionBar.setDisplayHomeAsUpEnabled(true);
actionBar.setHomeButtonEnabled(true);
actionBar.setElevation(0);

// Set the custom layout in actionbar here
actionBar.setCustomView(actionBarLayout);
actionBar.setDisplayOptions(actionBar.getDisplayOptions()
                | ActionBar.DISPLAY_SHOW_CUSTOM);

// Now handle the elements of the custom layout here
Button b1 = (Button) findViewById(R.id.button1);
// Set actions for Button 1 here
b1.setText("Button 1");

// Another element in custom actionbar
ImageView iv1 = (ImageView) findViewById(R.id.myImage);
iv1.setBackgroundResource(R.drawable.myImagePlaceHolder);

Place the codes in onCrate and check yourself.
