Firebase authentication with email and password extra fields duplicating - Android - Java

问题

我正在尝试使用电子邮件和密码对用户进行身份验证，并且当有人要注册时，我想要添加两个额外的字段（姓名和kredi）。但是当我注册我的应用时，还有两个带有“user”标签的字段保存到Firebase实时数据库中，如下所示：

  1. wohR9lJXnMgj9zCYMaasZDctrhf1
  2. kredi: 
  3. "20"
  4. name: 
  5. "test"
  6. userKredi: 
  7. "20"
  8. userName: 
  9. "test"

我不明白为什么会发生这种情况。这是我的注册活动代码：

  1. import androidx.annotation.NonNull;
  2. import androidx.appcompat.app.AppCompatActivity;
  4. // 导入省略...
  6. public class SignUpActivity extends AppCompatActivity {
  8.     // 控件和成员变量省略...
  10.     @Override
  11.     protected void onCreate(Bundle savedInstanceState) {
  12.         // 省略部分...
  13.     }
  14.     
  15.     private void signUp() {
  16.         // 省略部分...
  17.         final String kredi = "20";
  18.         final String name = kullaniciAdi.getText().toString().trim();
  19.         // 省略部分...
  20.     }
  22.     // 其他部分省略...
  23. }

以及Userinformation类：

  1. public class Userinformation {
  2.     public String name;
  3.     public String kredi;
  5.     public Userinformation(){
  6.     }
  8.     public Userinformation(String name,String kredi){
  9.         this.name = name;
  10.         this.kredi = kredi;
  11.     }
  12.     public String getUserName() {
  13.         return name;
  14.     }
  15.     public String getUserKredi() {
  16.         return kredi;
  17.     }
  18. }

我只想保存这些属性一次。我该如何做到这一点？

英文:

I'm trying to authanticate users with email and password and I want to add two extra fields (name and kredi) when someone going to sign-up. But when I sign-up to my app, two more fields with "user" tag saving to firebase realtime database like this:

  1. wohR9lJXnMgj9zCYMaasZDctrhf1
  2. kredi: 
  3. "20"
  4. name: 
  5. "test"
  6. userKredi: 
  7. "20"
  8. userName: 
  9. "test"

I don't understand why this is happening. This is my sign-up activity code:

  1. import androidx.annotation.NonNull;
  2. import androidx.appcompat.app.AppCompatActivity;
  4. import android.content.Intent;
  5. import android.os.Bundle;
  6. import android.text.TextUtils;
  7. import android.view.View;
  8. import android.widget.Button;
  9. import android.widget.EditText;
  10. import android.widget.Toast;
  12. import com.google.android.gms.tasks.OnCompleteListener;
  13. import com.google.android.gms.tasks.Task;
  14. import com.google.firebase.auth.AuthResult;
  15. import com.google.firebase.auth.FirebaseAuth;
  16. import com.google.firebase.database.DatabaseReference;
  17. import com.google.firebase.database.FirebaseDatabase;
  19. public class SignUpActivity extends AppCompatActivity {
  21.     EditText signUpMail,signUpPass,kullaniciAdi;
  22.     Button signUpButton;
  23.     private FirebaseAuth auth;
  24.     private DatabaseReference databaseReference;
  26.     @Override
  27.     protected void onCreate(Bundle savedInstanceState) {
  28.         super.onCreate(savedInstanceState);
  29.         setContentView(R.layout.activity_sign_up);
  31.         auth=FirebaseAuth.getInstance();
  33.         signUpMail = findViewById(R.id.signUpMail);
  34.         signUpPass = findViewById(R.id.signUpPass);
  35.         kullaniciAdi = findViewById(R.id.kullaniciAdi);
  36.         auth=FirebaseAuth.getInstance();
  37.         signUpButton = findViewById(R.id.signUpButton);
  39.         signUpButton.setOnClickListener(new View.OnClickListener() {
  40.             @Override
  41.             public void onClick(View view) {
  42.                 signUp();
  43.             }
  44.         });
  45.     }
  46.     private void signUp() {
  47.         final String email = signUpMail.getText().toString().trim();
  48.         final String pass = signUpPass.getText().toString().trim();
  49.         final String kredi = "20";
  50.         final String name = kullaniciAdi.getText().toString().trim();
  52.         if(TextUtils.isEmpty(email)){
  53.             Toast.makeText(getApplicationContext(),"Please enter your E-mail address",Toast.LENGTH_LONG).show();
  54.             return;
  55.         }
  56.         if(TextUtils.isEmpty(pass)){
  57.             Toast.makeText(getApplicationContext(),"Please enter your Password",Toast.LENGTH_LONG).show();
  58.         }
  59.         if (pass.length() == 0){
  60.             Toast.makeText(getApplicationContext(),"Please enter your Password",Toast.LENGTH_LONG).show();
  61.         }
  62.         if (pass.length()<8){
  63.             Toast.makeText(getApplicationContext(),"Password must be more than 8 digit",Toast.LENGTH_LONG).show();
  64.         }
  65.         else{
  66.             auth.createUserWithEmailAndPassword(email,pass)
  67.                     .addOnCompleteListener(SignUpActivity.this, new OnCompleteListener<AuthResult>() {
  68.                         @Override
  69.                         public void onComplete(@NonNull Task<AuthResult> task) {
  71.                             if (task.isSuccessful()) {
  73.                                 Userinformation userinformation = new Userinformation(
  74.                                         name,
  75.                                         kredi
  76.                                 );
  78.                                 databaseReference = FirebaseDatabase.getInstance().getReference();
  79.                                 databaseReference.child(FirebaseAuth.getInstance().getCurrentUser().getUid()).setValue(userinformation).addOnCompleteListener(new OnCompleteListener<Void>() {
  80.                                     @Override
  81.                                     public void onComplete(@NonNull Task<Void> task) {
  82.                                         if(task.isSuccessful()){
  83.                                             startActivity(new Intent(SignUpActivity.this, HomeActivity.class));
  84.                                             finish();
  85.                                         }
  86.                                         else{
  87.                                             Toast.makeText(SignUpActivity.this, task.getException().getMessage(),Toast.LENGTH_LONG).show();
  88.                                         }
  89.                                     }
  90.                                 });
  92.                             }
  93.                             else {
  94.                                 Toast.makeText(SignUpActivity.this, task.getException().getMessage(),Toast.LENGTH_LONG).show();
  95.                             }
  96.                         }
  97.                     });
  98.         }
  99.     }
  100.     public void navigate_sign_in(View v){
  101.         Intent inent = new Intent(this, SignInActivity.class);
  102.         startActivity(inent);
  103.     }
  104. }

and Userinformation class:

  1. public class Userinformation {
  2.     public String name;
  3.     public String kredi;
  5.     public Userinformation(){
  6.     }
  8.     public Userinformation(String name,String kredi){
  9.         this.name = name;
  10.         this.kredi = kredi;
  11.     }
  12.     public String getUserName() {
  13.         return name;
  14.     }
  15.     public String getUserKredi() {
  16.         return kredi;
  17.     }
  18. }

I just want to save those properties just once. How can I do this?

问题出在你的POJO类上，请将代码更改为：

  1. public String getName() {
  2.     return name;
  3. }
  4. public String getKredi() {
  5.     return kredi;
  6. }
英文:

The problem is at your pojo, change this

  1. public String getUserName() {
  2.         return name;
  3.     }
  4.     public String getUserKredi() {
  5.         return kredi;
  6.     }

to this

  1. public String getName() {
  2.         return name;
  3.     }
  4.     public String getKredi() {
  5.         return kredi;
  6.     }
