Is it possible to centre the actionbar title from a fragment using AndroidX navigation?

Question

Currently, I am using the Navigation component from Android and the actionbar title is displayed on the left. However, I kind of want it centralised to make things neater, is there any way to go about doing so?

Activity's code:

public class General extends AppCompatActivity {
    private BottomNavigationView bottomNavigationView;
    private NavController navController;
    private AppBarConfiguration appBarConfiguration;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.general);

        bottomNavigationView = findViewById(R.id.bottomNavigationView);
        navController = Navigation.findNavController(this,  R.id.fragment);

        appBarConfiguration = new AppBarConfiguration.Builder(R.id.addFragment, R.id.homeFragment).build();

        NavigationUI.setupWithNavController(bottomNavigationView, navController);
        NavigationUI.setupActionBarWithNavController(this, navController, appBarConfiguration);
    }
}

Activity's XML Code

    tools:context=".General">

        android:layout_height="wrap_content"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:menu="@menu/bottom_navigation_menu">

    </com.google.android.material.bottomnavigation.BottomNavigationView>

    <fragment
        android:id="@+id/fragment"
        android:name="androidx.navigation.fragment.NavHostFragment"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        app:defaultNavHost="true"
        app:layout_constraintBottom_toTopOf="@+id/bottomNavigationView"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent"
        app:navGraph="@navigation/the_navigation" />

</androidx.constraintlayout.widget.ConstraintLayout>

Fragment XML Code:

<?xml version="1.0" encoding="utf-8"?>
<navigation xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/the_navigation"
    app:startDestination="@id/homeFragment">

    <fragment
        android:id="@+id/homeFragment"
        android:name="com.test.HomeFragment"
        android:label="Home"
        tools:layout="@layout/home_fragment" />
    <fragment
        android:id="@+id/addFragment"
        android:name="com.test.AddFragment"
        android:label="Add"
        tools:layout="@layout/add_fragment" />
</navigation>

Would you be kind enough to point me in the right direction if I am to use the toolbar? I would highly appreciate it if you include code snippets on how to integrate my code with the toolbar :D — 風の歌, Jan 24 '21 at 14:57
[official docs](https://developer.android.com/training/appbar/setting-up#add-toolbar) are a good place to start — Sekiro, Jan 24 '21 at 15:59
Try adding a custom toolbar to the activity then try the link provided above. Also, you need to add ```false true``` to the style. — private static, Jan 24 '21 at 23:51

After a bit of searching, it seems like this did the trick. All I had to do was to add it to my Activity code.
