Post only the relevant code where you getting error, need improve, etc. Don't post whole code. Its difficult for everyone to figure out the problem. — Shabbir Dhangot, May 07 '16 at 07:38

You can pass your city name from MainActivity to UserActivity using intent.

Where you're starting your UserActivity from MainActivity, use putExtra(String, String) of Intent.

For Example: In MainActivity

Intent i = new Intent(MainActivity.this, UserActivity.class);
i.putExtra("Title", yourCityName);
startActivity(i);

And in UserActivity

String cityName = getIntent().getExtra("Title", "Default City Name");
toolbar.setTitle(cityName);

Or you can try with

getSupportActionBar().setTitle(cityName);

after doing

setSupportActionBar(toolbar);

Create one class of Constant.

public class Constant {
    public static  String CITY_NAME ="";

    public static String getCityName() {
        return CITY_NAME;
    }

    public static void setCityName(String cityName) {
        Constant.CITY_NAME = cityName;
    }
}

Now when you get the city name you save this city name here like

Constant.setCityName("ANY");

And when you want to retrieve city name from any class or any activity you can get it from here like this

Constant.getCityName();

This name is store until your app open. So no need to pass on each activity intent. This is the way you can get city name from anywhere from your application.

And your Question Solution

At MainActivity

toolbar.setTitle(cityName);
Constant.setCityName(cityName);
setActionBar(toolbar);

At UserActivity

toolbar.setTitle("how i should call that cityName here");

change this line to

toolbar.setTitle(Constant.getCityName());

You can save your city name using shared preference like this:

SharedPreferences sharedpreferences = getSharedPreferences("your preference name", Context.MODE_PRIVATE); Editor editor = sharedpreferences.edit(); editor.putString("cityname", your city name); editor.commit();

now wherever you want to use your city name:

SharedPreferences sharedpreferences = getSharedPreferences("your preference name", Context.MODE_PRIVATE); String cityname=sharedpreferences.getString("cityname"); toolbar.setTitle(cityname);

This will create problem if MainActivity is closed and throw exception. I mean Activity is not in the activity stack user has finish that activity. What you think? – Shabbir Dhangot May 07 '16 at 08:02

@Shabbir Dhangot,why MainActivity closed? – Rgv May 07 '16 at 08:46
I mean if developer not need main activity then he finish it. at that time you answer wont work and activity will crash – Shabbir Dhangot May 07 '16 at 11:04
@Shabbir Dhangot,from ur answer,if developer not set any value but he using get method then what happend? – Rgv May 07 '16 at 11:17
it returns null. If user not setting city and still want to retrieve than obviously it returns null. Its like you create an object not initialized and still you are using it. you need to take care about the initialization. In other way if we initialize CITY_NAME with "" it wont return null anyway. I hope you got the idea – Shabbir Dhangot May 07 '16 at 11:21
