Firebase 登录并使用用户名注册 [英] Firebase login and signup with username

问题描述

我目前正在使用 AndroidHive 的 tutorial 学习如何使用 Firebase，我现在开始很好地理解方法和文档 - 我意识到 Firebase 提供了一个带有电子邮件和密码的注册/登录方法，而这条信息不是存储在我们的数据库中.

I am currently using AndroidHive's tutorial to learn how to use Firebase, I am starting to understand the methods and documentation well now - I realised that Firebase offers a signup/sign-in method with email and password, and that this piece of information is not stored in our database.

我想实现一个系统，当他们注册时，他们提供他们的电子邮件、密码和用户名以及一些其他数据，并且所有这些都被保存到数据库中.这样用户就可以使用他们的电子邮件或用户名登录.我在堆栈上发现这篇文章显然是 回答 我问的这个问题 - 但是，我不完全理解这一点以及它如何与我下面的代码相关联

I would like to implement a system where when they sign up they provide their email,password and a username along with some other data and it all gets saved to the database. So that the user can then signin with their email or username. I found this article on stack which apparently is the answer to this question I am asking - However, I do not fully understand this and how it links with my code below

auth.createUserWithEmailAndPassword(email, password)
.addOnCompleteListener(SignupActivity.this, new OnCompleteListener<AuthResult>() {
@Override
public void onComplete(@NonNull Task<AuthResult> task) {
    Toast.makeText(SignupActivity.this, "createUserWithEmail:onComplete:" + task.isSuccessful(), Toast.LENGTH_SHORT).show();
    progressBar.setVisibility(View.GONE);

    if (!task.isSuccessful()) {
        Toast.makeText(SignupActivity.this, "Authentication failed." + task.getException(),
            Toast.LENGTH_SHORT).show();
    } else {
        startActivity(new Intent(SignupActivity.this, MainActivity.class));
        finish();
    }
}
});

非常感谢任何帮助

推荐答案

试试这个:

auth.createUserWithEmailAndPassword(email, password)
.addOnCompleteListener(SignupActivity.this, new OnCompleteListener<AuthResult>() {
@Override
public void onComplete(@NonNull Task<AuthResult> task) {
    Toast.makeText(SignupActivity.this, "createUserWithEmail:onComplete:" + task.isSuccessful(), Toast.LENGTH_SHORT).show();
    progressBar.setVisibility(View.GONE);
    generateUser(email, password)

    if (!task.isSuccessful()) {
        Toast.makeText(SignupActivity.this, "Authentication failed." + task.getException(),
            Toast.LENGTH_SHORT).show();
    } else {
        startActivity(new Intent(SignupActivity.this, MainActivity.class));
        finish();
    }
}
});

这是上面调用的方法.

public void generateUser(String username, String password)
{

FirebaseDatabase database = FirebaseDatabase.getInstance();
DatabaseReference users = database.getReference("users"); //users is a node in your Firebase Database.
User user = new User(username, password); //ObjectClass for Users
users.push().setValue(user);

}

还有:用户类

   public class User {

    String username;
    String password;

    public User() {
    //Empty Constructor For Firebase
    }


public User(String username, String password)
        {
        this.username = username; //Parameterized for Program-Inhouse objects.
        this.password = password;
        }

    //Getters and Setters
    public String getUsername()
    {
    return username;
    }
    public void setUsername(String username)
    {
    this.username = username;
    }
    public String getPassword()
    {
    return password;
    }
    public void setPassword(String password)
    {
    this.password = password;
    }
}
