Question

[Terroris337]

Доброго времени суток, пытаюсь передать данные из активности в фрагмент и получаю ошибку при получении данных в фрагменте:

java.lang.NullPointerException: Attempt to invoke virtual method 'java.lang.String android.os.Bundle.getString(java.lang.String)' on a null object reference

В активности передаю данные так:

FragmentManager fragmentManager = getSupportFragmentManager();
                    FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
                    Bundle bundle = new Bundle();
                    bundle.putString("username", response.body().getName());
                    bundle.putString("email", response.body().getEmail());
                    bundle.putString("phone", response.body().getPhone());
                    ProfileFragment profileFragment = new ProfileFragment();
                    profileFragment.setArguments(bundle);
                    fragmentTransaction.commit();

ProfileFragment:

public class ProfileFragment extends Fragment {

    private FragmentProfileBinding binding;

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

        binding = FragmentProfileBinding.inflate(inflater, container, false);
        View root = binding.getRoot();

        final TextView textViewUsername = binding.textUsername;
        final TextView textViewEmail = binding.textEmail;
        final TextView textViewPhone = binding.textPhone;

        textViewUsername.setText(this.getArguments().getString("username")); // ошибку бьет тут

        return root;
    }

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

Сейчас есть отличный
https://developer.android.com/guide/navigation/nav...

А по старинке, когда мне нужно было ручками добавлять фрагмент с предустановленным аргументом, я сделал так

fragment = TxtFragment.newInstanceWithUri(uri);
fragmentManager.beginTransaction().replace(R.id.flContent, fragment).commit();

Написал свой статический инстанс гет с параметром

static public TxtFragment newInstanceWithUri(Parcelable param1) {
        TxtFragment fragment = new TxtFragment();
        fragment.parcelable = param1;
        return fragment;
    }
