How do I set text on spinner (get input from firebase)? - firebase

Question

I want to set text on spinner by user input by using DatabaseReference, but I'm lost with all the guides I read on here
Here is my code
public class EditFragment extends Fragment {
TextInputEditText etusername, etname, etage, height, weight, phone;
Spinner gender;
Button confirm;
FirebaseDatabase db = FirebaseDatabase.getInstance();
DatabaseReference root = db.getInstance().getReference();
FirebaseAuth firebaseAuth = FirebaseAuth.getInstance();
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View view = inflater.inflate(R.layout.fragment_edit, container, false);
etusername = view.findViewById(R.id.userName);
etname = view.findViewById(R.id.name);
etage = view.findViewById(R.id.age);
height = view.findViewById(R.id.height);
weight = view.findViewById(R.id.etweight);
phone = view.findViewById(R.id.phone);
confirm = view.findViewById(R.id.confirmBtn);
Spinner dropdown = view.findViewById(R.id.gender);
String[] items = new String[]{"Male", "Female"};
ArrayAdapter<String> adapter = new ArrayAdapter<>(getActivity(), android.R.layout.simple_spinner_dropdown_item, items);
dropdown.setAdapter(adapter);
DatabaseReference dbuser = FirebaseDatabase
.getInstance()
.getReference("User").child(firebaseAuth.getUid());
dbuser.addListenerForSingleValueEvent(new ValueEventListener() {
#Override
public void onDataChange(#NonNull DataSnapshot snapshot) {
User userProfile = snapshot.getValue(User.class);
etusername.setText(userProfile.getUsername());
etname.setText(userProfile.getName());
etage.setText(userProfile.getAge() + "");
phone.setText(userProfile.getPhoneNumber());
weight.setText((int) userProfile.getWeight() + "");
height.setText((int) userProfile.getHeight() + "");
**--> dropdown.setSelection**
}
#Override
public void onCancelled(#NonNull DatabaseError error) {
Log.w("TAG", "Failed to read value.", error.toException());
}
});
confirm.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
if (etusername.getText().toString().isEmpty() || etname.getText().toString().isEmpty() ||
etage.getText().toString().isEmpty() || phone.getText().toString().isEmpty()) {
Toast.makeText(requireContext(), "Please fill in the text fields", Toast.LENGTH_SHORT).show();
} else {
Toast.makeText(requireContext(), "Saved successfully", Toast.LENGTH_SHORT).show();
String username = etusername.getText().toString();
String name = etname.getText().toString();
int age = Integer.parseInt(etage.getText().toString());
double high = Double.parseDouble(Objects.requireNonNull(height.getText()).toString());
double wigh = Double.parseDouble(Objects.requireNonNull(weight.getText()).toString());
String nump = phone.getText().toString();
String gender = dropdown.getSelectedItem().toString();
HashMap<String, Object> userMap = new HashMap<>();
userMap.put("username", username);
userMap.put("name", name);
userMap.put("age", age);
userMap.put("height", high);
userMap.put("weight", wigh);
userMap.put("phoneNumber", nump);
userMap.put("gender", gender);
root.child("User").child(Objects.requireNonNull(firebaseAuth.getUid())).updateChildren(userMap);
Navigation.findNavController(view).navigate(R.id.DestInfo);
}
}
});
return view;
}
}
I don't know how to make it work for dropdown to be set from user input, is there anything I can simply do? or do I need to do the for loop? but how do I get the UserProfile.getGender index? I'm sorry I'm kinda new to this android studio, but I'm trying to learn
