在Android中注册Firebase时存储其他信息 [英] Store additional information during registration with Firebase in Android

问题描述

我尝试通过发送电子邮件和密码来使用Firebase身份验证来创建用户。现在我想在用户创建后存储名字和姓氏。由于我是Android和Firebase的新手，我只是不知道该怎么做。任何人都可以帮助我吗？

我的代码：

  public类RegistrationActivity扩展了AppCompatActivity {
 
 private FirebaseAuth auth; 
按钮取消，提交; 
 EditText电子邮件，密码，名字，姓氏; 
私人ProgressDialog progressDialog; 
 
 @Override 
 protected void onCreate（Bundle savedInstanceState）{
 super.onCreate（savedInstanceState）; 
 setContentView（R.layout.activity_registration）; 
 
 progressDialog = new ProgressDialog（this）; 
 
 email =（EditText）findViewById（R.id.email）; 
 password =（EditText）findViewById（R.id.password）; 
 firstName =（EditText）findViewById（R.id.firstName）; 
 lastName =（EditText）findViewById（R.id.lastName）; 
 
 submit =（Button）findViewById（R.id.submit）; 
 submit.setOnClickListener（new View.OnClickListener（）{
 @Override 
 public void onClick（View view）{
 String inputEmail = email.getText（）。toString（）。 trim（）; 
 String inputPassword = password.getText（）。toString（）。trim（）; 
 registerUser（）; 
} 
}）; 
 
 
 private void registerUser（）{
 final String inputFirstName = firstName.getText（）。toString（）; 
 String inputLastName = lastName.getText（）。toString（）; 
 final String inputEmail = email.getText（）。toString（）; 
 String inputPassword = password.getText（）。toString（）; 
 
 progressDialog.setMessage（Registering ..）; 
 progressDialog.show（）; 
 $ b $ //创建用户
 auth.createUserWithEmailAndPassword（inputEmail，inputPassword）
 .addOnCompleteListener（RegistrationActivity.this，new OnCompleteListener< AuthResult>（）{
 @Override 
 public void onComplete（@NonNull Task< AuthResult> task）{
 if（！task.isSuccessful（））{
 Toast.makeText（RegistrationActivity.this，Authentication failed。+ task。 getException（），
 Toast.LENGTH_SHORT）.show（）; 
} else {
 Toast.makeText（RegistrationActivity.this，User created successfully。，Toast.LENGTH_SHORT）.show ）; 
 progressDialog.hide（）; 
 startActivity（new Intent（RegistrationActivity.this，MainActivity.class））; 
} 
} 
}）; 
 
  

解决方案

您可以创建一个用户类像这样：

  public class User {
 
 String name; 
字符串姓氏; 
字符串网站; 
 ... 
 $ b $ public User（）{
 //所需的默认构造函数
} 
 $ b $ public void setName（String name） {this.name = name;} 
 public void setSurname（String surname）{this.surname = surname;} 
 public void setWebsite（String website）{this.website = website;} 
 
 public String getName（）{return name; } 
 ..... 
 
} 
  

使用它：

  User user = new User（）; 
 user.setName（xxxx）; 
 user.setSurname（xxxx）; 
 user.setWebsite（xxxx）; 
 
 mDatabase.child（users）。push（）。setValue（user）; 
  

I tried to create a user using Firebase Auth by sending an email and a password. Now I want to store the first name and last name after a user is created. Since I am new to Android and Firebase, I just don't see how to do that. Can anyone help me on this?

My code:

public class RegistrationActivity extends AppCompatActivity {

private FirebaseAuth auth;
Button cancel, submit;
EditText email, password, firstName, lastName;
private ProgressDialog progressDialog;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_registration);

    progressDialog = new ProgressDialog(this);

    email = (EditText) findViewById(R.id.email);
    password = (EditText) findViewById(R.id.password);
    firstName = (EditText) findViewById(R.id.firstName);
    lastName = (EditText) findViewById(R.id.lastName);

    submit = (Button) findViewById(R.id.submit);
    submit.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            String inputEmail = email.getText().toString().trim();
            String inputPassword = password.getText().toString().trim();
            registerUser();
        }
    });
}

private void registerUser(){
    final String inputFirstName = firstName.getText().toString();
    String inputLastName = lastName.getText().toString();
    final String inputEmail = email.getText().toString();
    String inputPassword = password.getText().toString();

    progressDialog.setMessage("Registering..");
    progressDialog.show();

    //create user
    auth.createUserWithEmailAndPassword(inputEmail, inputPassword)
            .addOnCompleteListener(RegistrationActivity.this, new OnCompleteListener<AuthResult>() {
                @Override
                public void onComplete(@NonNull Task<AuthResult> task) {
                    if (!task.isSuccessful()) {
                        Toast.makeText(RegistrationActivity.this, "Authentication failed." + task.getException(),
                                Toast.LENGTH_SHORT).show();
                    } else {                      
                        Toast.makeText(RegistrationActivity.this, "User created successfully.", Toast.LENGTH_SHORT).show();
                        progressDialog.hide();
                        startActivity(new Intent(RegistrationActivity.this, MainActivity.class));
                    }
                }
            });
}

解决方案

You can create a user class like this:

public class User{

 String name;
 String surname;
 String website;
 ....

 public User(){
   // Default constructor required
 }

 public void setName(String name){this.name = name;}
 public void setSurname(String surname){this.surname = surname;}
 public void setWebsite(String website){this.website = website;}

 public String getName(){ return name; }
 .....

}

Then just use it:

User user = new User();
user.setName("xxxx");
user.setSurname("xxxx");
user.setWebsite("xxxx");

mDatabase.child("users").push().setValue(user);
