我在一个应用程序中工作，我使用底部导航。我有四个菜单选项在底部的一个菜单后广告我有一个按钮（“开始列出您的财产”），通过它我进入了另一个片段，但问题是，底部导航菜单也显示在那里，现在我怎么能停止显示这一点呢？
我附上了照片

主要活动

public class MainActivity extends AppCompatActivity {

NavController navController;
BottomNavigationView bottomNavigationView;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    navController = Navigation.findNavController(this, R.id.fragmentContainerView);
    bottomNavigationView = findViewById(R.id.activity_main_bottom_navigation_view);
    NavigationUI.setupWithNavController(bottomNavigationView, navController);

}

public void setBottomNavigationVisibility(int visibility) {

    MainActivity activity = new MainActivity();
    bottomNavigationView.setVisibility(visibility);
}}

我不想使用底部导航的活动的代码

public class Details_Added_Fragment extends Fragment {

private PageViewModel viewModel;
FragmentDetailsAddedBinding binding;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {

    binding = FragmentDetailsAddedBinding.inflate(inflater, container, false);

    // Inflate the layout for this fragment
    View view =  binding.getRoot();

    viewModel = new ViewModelProvider(requireActivity()).get(PageViewModel.class);

    ((MainActivity) requireActivity()).setBottomNavigationVisibility(View.GONE);

    binding.toolbar.setNavigationOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
           Navigation.findNavController(view).navigate(R.id.action_secondFragment2_to_postad);
        }
    });


    binding.next2.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {

                enterName(binding.edittextName.getText().toString());
                enterEmail(binding.edittextName.getText().toString());
                enterDesc(binding.edittexDesc.getText().toString());

                Navigation.findNavController(view).navigate(R.id.action_secondFragment2_to_lastFragment);

        }
    });

    return view;
}

@Override
public void onDestroyView() {
    super.onDestroyView();
    binding = null;
}

public void enterName(String name)
{
    viewModel.setName(name);
}

public void enterEmail(String email)
{
    viewModel.setEmail(email);
}

public void enterDesc(String desc)
{
    viewModel.setDescription(desc);
}

}
