Android 使用不同菜单的导航抽屉和底部导航栏时出现问题

在其中同时使用了这两种方法的java类

import android.content.Intent;

    @Override

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

        appBarConfiguration = new AppBarConfiguration.Builder(new int[]{R.id.home, R.id.addNewProduct, R.id.notifications,R.id.user_details,R.id.settings,R.id.help})
                        .setDrawerLayout(drawerLayout)
                        .build();

    }



    public boolean onSupportNavigateUp(){

    }


    @Override
    public boolean onNavigationItemSelected(@NonNull MenuItem menuItem) {
        Fragment fragment = null;

        int id= menuItem.getItemId();
        if(id == R.id.user_details)
        {

           startActivity(new Intent(NavigActivity.this, MainActivity.class));
        }

        if(fragment != null)
        {
            FragmentManager fragmentManager = getSupportFragmentManager();
            FragmentTransaction ft = fragmentManager.beginTransaction();
            ft.replace(R.id.content_frame, fragment);
            ft.commit();

        }

        DrawerLayout drawer = (DrawerLayout)findViewById(R.id.drawer);
        drawer.closeDrawer(GravityCompat.START);
            return true;
    }
}

这是一个布局文件

<?xml version="1.0" encoding="utf-8"?>

其布局文件为

    xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent"
    android:layout_height="match_parent">

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="User"
        android:textSize="28dp"
        android:layout_centerInParent="true"
        />

</RelativeLayout>

任何帮助都将不胜感激。如果有人能建议在同一个应用程序中使用导航抽屉和底部导航的更好方法，我将非常感谢他

<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent"
    android:layout_height="match_parent">

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="User"
        android:textSize="28dp"
