In order to help, please add some code, especially the code behind the buttons you are using. — Strider, Feb 16 '16 at 10:37
to save the state , you need some persistence storage, [SharedPreferences](http://stackoverflow.com/questions/3851560/how-to-use-sharedpreferences) is what you are looking for. — nobalG, Feb 16 '16 at 10:41

You can use SharedPreferences to keep username, without database. And when you click on logout button, call login screen again and read username from Preferences. An example code below:

public static final String MyPREFERENCES = "MyPrefs";
public static final String USERNAME_KEY = "counter";

public static String getUsername(Context context) {
        SharedPreferences prefs = context.getSharedPreferences(MyPREFERENCES, context.MODE_PRIVATE);
        return prefs.getString(USERNAME_KEY, null);
    }

public static void setUserEmailToPreference(Context context, String username) {

    SharedPreferences.Editor editor = context.getSharedPreferences(MyPREFERENCES, context.MODE_PRIVATE).edit();
    editor.putString(USERNAME_KEY, username);
    editor.commit();
}

Now you only need to call these methods. Best regards. Uilton.
