I use Android Studio 4.0.1 to develop it. The following is my result...

About BottomNavigationViewHelper.java My code is work here

import com.google.android.material.bottomnavigation.BottomNavigationItemView;
import com.google.android.material.bottomnavigation.BottomNavigationMenuView;
import com.google.android.material.bottomnavigation.BottomNavigationView;
import com.google.android.material.bottomnavigation.LabelVisibilityMode;
import android.annotation.SuppressLint;
import android.util.Log;
import java.lang.reflect.Field;
public class BottomNavigationViewHelper {
    @SuppressLint("RestrictedApi")
    public static void disableShiftMode(BottomNavigationView view) {
        view.setLabelVisibilityMode(LabelVisibilityMode.LABEL_VISIBILITY_LABELED);
        BottomNavigationMenuView menuView = (BottomNavigationMenuView) view.getChildAt(0);
        try {
            Field shiftingMode = menuView.getClass().getDeclaredField("mShiftingMode");
            shiftingMode.setAccessible(true);
            shiftingMode.setBoolean(menuView, false);
            shiftingMode.setAccessible(false);
            for (int i = 0; i < menuView.getChildCount(); i++) {
                BottomNavigationItemView item = (BottomNavigationItemView) menuView.getChildAt(i);
                //noinspection RestrictedApi
                item.setShifting(false);
                item.setLabelVisibilityMode( LabelVisibilityMode.LABEL_VISIBILITY_LABELED);
                // set once again checked value, so view will be updated
                //noinspection RestrictedApi
                item.setChecked(item.getItemData().isChecked());
            }
        } catch (NoSuchFieldException e) {
            Log.e("BNVHelper", "Unable to get shift mode field", e);
        } catch (IllegalAccessException e) {
            Log.e("BNVHelper", "Unable to change value of shift mode", e);
        }
    }
}

Then we can start to use BottomNavigationViewHelper class And this is my code for MainActivity.java.

BottomNavigationView navView = findViewById(R.id.nav_view); BottomNavigationViewHelper.disableShiftMode(navView);

import android.os.Bundle;
import com.google.android.material.bottomnavigation.BottomNavigationView;
import androidx.appcompat.app.AppCompatActivity;
import androidx.navigation.NavController;
import androidx.navigation.Navigation;
import androidx.navigation.ui.AppBarConfiguration;
import androidx.navigation.ui.NavigationUI;
public class MainActivity extends AppCompatActivity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        BottomNavigationView navView = findViewById(R.id.nav_view);
        BottomNavigationViewHelper.disableShiftMode(navView);
        // Passing each menu ID as a set of Ids because each
        // menu should be considered as top level destinations.
        AppBarConfiguration appBarConfiguration = new AppBarConfiguration.Builder(
                R.id.navigation_settings,
                R.id.navigation_connection,
                R.id.navigation_status,
                R.id.navigation_report,
                R.id.navigation_profile
        ).build();

        NavController navController = Navigation.findNavController(this, R.id.nav_host_fragment);
        NavigationUI.setupActionBarWithNavController(this, navController, appBarConfiguration);
        NavigationUI.setupWithNavController(navView, navController);
        getSupportActionBar().hide();
    }
}
