Unable to set title in fragment in Android

Question

I am using the default navigational drawer in Android. I want to change the title of the Action bar depending on the clicked fragment in the drawer. For this I am writing below line in my code:

getActivity().getActionBar().setTitle("Coupons");

This is returning null object. So I tried using below line of code:

getActivity().getSupportActionBar().setTitle("Coupons");

This is not able to resolve the method supportActionBar(). The activity is AppCompatActivity.

You need a listener, you cannot change dynamically like this, check this answer: https://stackoverflow.com/questions/15560904/setting-custom-actionbar-title-from-fragment/15561031 — Azhagthott, Jan 31 '20 at 07:21

All the titles and strings are placed in strings.xml file in the android studio. Open strings.xml and change existing text to "Coupons".

strings.xml is placed here in the project view. Strings.xml location in Android Studio
