OnBackPressedCallback内部的NavController问题

@Override
public void onCreate(@Nullable Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    requireActivity().getOnBackPressedDispatcher().addCallback(this, new OnBackPressedCallback(true) {
        @Override
        public void handleOnBackPressed() {
            // 自定义后退逻辑
        }
    });
}

NavController navController = Navigation.findNavController(view);

public class MyFragment extends Fragment {

    @Override
    public void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        requireActivity().getOnBackPressedDispatcher().addCallback(this, new OnBackPressedCallback(true) {
            @Override
            public void handleOnBackPressed() {
                NavController navController = Navigation.findNavController(requireView());
                if (navController.getCurrentDestination().getId() != R.id.homeFragment) {
                    navController.navigateUp(); // 返回上一级
                } else {
                    // 如果已经在首页，执行默认的后退行为
                    setEnabled(false);
                    requireActivity().onBackPressed();
                }
            }
        });
    }
}
