如何在我的编码 android studio 项目中实现此代码 setDisplayName？

Question

i would like to implement my the setDisplayName() into my code but not sure on how to do it. where should i put the setDisplayName inside my code ? i want to display the customer name inside my nav bar header.

this is my code

//create customer
firebaseAuth.createUserWithEmailAndPassword(email, password).addOnCompleteListener(RegisterActivity.this, new OnCompleteListener < AuthResult > () {
    @Override
    public void onComplete(@NonNull Task < AuthResult > task) {
        if (task.isSuccessful()) {
            Customer info = new Customer(name, email, address, number, gender);

            FirebaseDatabase.getInstance().getReference("Customer")
                .child(Objects.requireNonNull(FirebaseAuth.getInstance().getCurrentUser()).getUid())
                .setValue(info).addOnCompleteListener(new OnCompleteListener < Void > () {
                    @Override
                    public void onComplete(@NonNull Task < Void > task) {
                        regProgressBar.setVisibility(View.VISIBLE);
                        Toast.makeText(RegisterActivity.this, "Registration Complete", Toast.LENGTH_SHORT).show();
                        startActivity(new Intent(getApplicationContext(), Home.class));
                    }
                });
        }
    }
});

and this is code that i found but in not sure on how to implement this inside my code.

mAuth.createUserWithEmailAndPassword(email, password).addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {
    @Override
    public void onComplete(@NonNull Task<AuthResult> task) {
        if(task.isSuccessful()){
            // Sign in is successful
            FirebaseUser user = FirebaseAuth.getInstance().getCurrentUser();

            UserProfileChangeRequest profileUpdates = new UserProfileChangeRequest.Builder()
                    .setDisplayName(mName).build();

            user.updateProfile(profileUpdates)
                    .addOnCompleteListener(new OnCompleteListener<Void>() {
                        @Override
                        public void onComplete(@NonNull Task<Void> task) {
                            if (task.isSuccessful()) {
                                Log.d(TAG, "User profile updated.");
                            }
                        }
                    });
        }
    });
}

this is my Customer java class

package com.example.gerobokgo;

public class Customer {
    public String name,email,home_address,telephone_number,gender;

    public Customer(){

    }

    public Customer(String name, String email, String home_address, String telephone_number, String gender) {
        this.name = name;
        this.email = email;
        this.home_address = home_address;
        this.telephone_number = telephone_number;
        this.gender = gender;
    }
}

The code flow will be following :

1. User Register with Email and password.
2. Then you set User display name UserProfileChangeRequest with FirebaseAuth.

3. After it successfully complete. Your data will be save in Database

   mAuth.createUserWithEmailAndPassword(email, password).addOnCompleteListener(this, new OnCompleteListener<AuthResult>() { @Override public void onComplete(@NonNull Task<AuthResult> task) { if(task.isSuccessful()){ // Sign in is successful FirebaseUser user = FirebaseAuth.getInstance().getCurrentUser(); UserProfileChangeRequest profileUpdates = new UserProfileChangeRequest.Builder() .setDisplayName(name).build(); user.updateProfile(profileUpdates) .addOnCompleteListener(new OnCompleteListener<Void>() { @Override public void onComplete(@NonNull Task<Void> task) { if (task.isSuccessful()) { Customer info = new Customer(name, email, address, number, gender); FirebaseDatabase.getInstance().getReference("Customer") .child(Objects.requireNonNull(FirebaseAuth.getInstance().getCurrentUser()).getUid()) .setValue(info).addOnCompleteListener(new OnCompleteListener < Void > () { @Override public void onComplete(@NonNull Task < Void > task) { regProgressBar.setVisibility(View.VISIBLE); Toast.makeText(RegisterActivity.this, "Registration Complete", Toast.LENGTH_SHORT).show(); startActivity(new Intent(getApplicationContext(), Home.class)); } }); } } }); } }); }
