Unable to retrive data from firebase android studio

public class Userprofile extends Fragment {

    private FragmentUserprofileBinding binding;

    FirebaseAuth firebaseAuth;

    FirebaseDatabase db= FirebaseDatabase.getInstance();

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

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

        View root = binding.getRoot();

        View view = inflater.inflate(R.layout.fragment_userprofile, container, false);

        AppCompatDelegate.setDefaultNightMode(AppCompatDelegate.MODE_NIGHT_NO);

        String x= phoneNoClass.getMobileNoOfDoctor();

        binding.logout.setOnClickListener(new View.OnClickListener() {

            @Override

            public void onClick(View v) {

                firebaseAuth.signOut();
            }
        });

        DatabaseReference roat=db.getReference("DoctorData").child("+919937336406");

        roat.get().addOnCompleteListener(new OnCompleteListener<DataSnapshot>() {

            @Override

            public void onComplete(@NonNull Task<DataSnapshot> task) {

                if (task.isSuccessful()){

                    Toast.makeText(getContext(), "updating....."+task.getException(), Toast.LENGTH_SHORT).show();

                    String uname=String.valueOf(task.getResult().child("name").getValue());

                    binding.UserName.setText(uname);

                }else {

                    Toast.makeText(getContext(), "unable"+task.getException(), Toast.LENGTH_SHORT).show();
                }
            }
        });

        return view;
    }

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

According to your comment:

yes the result is showing in the log but not in the app.

The problem isn't related to Firebase, it's a problem related to the way you are using data binding. So the simplest solution is to use View's findViewById(int id) method to refer to your UserName TextView.
