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

Question

我想将我的 setDisplayName() 实现到我的代码中，但不确定如何去做。我应该将 setDisplayName 放在我的代码中的什么位置？我想在我的导航栏标题中显示客户名称。

这是我的代码

//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));
                    }
                });
        }
    }
});

这是我找到的代码，但不确定如何在我的代码中实现它。

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.");
                            }
                        }
                    });
        }
    });
}

这是我的客户java类

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;
    }
}

代码流程如下:

1. 用户使用电子邮件和密码注册。
2. 然后使用 FirebaseAuth 设置用户显示名称 UserProfileChangeRequest。

3. 成功完成后。您的数据将保存在数据库中

   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));
                                           }
                                       });
                               }
                           }
                       });
           }
       });
   }
