We can change the ActionBar title in one of two ways:

1. In the Manifest: in the manifest file, set the label of each Activity.

   android:label="@string/TitleWhichYouWantToDisplay"
   

2. In code: in code, call the setTitle() method with a String or the id of String as the argument.

   public class MainActivity extends Activity {
   
       @Override
       public void onCreate(Bundle savedInstanceState) {
   
           setTitle(R.string.TitleWhichYouWantToDisplay);
           // OR You can also use the line below
           // setTitle("MyTitle")
           setContentView(R.layout.activity_main);
   
       }
   }
