我正在制作具有用户个人资料的社交媒体应用。我想在完成注册后保存他们的个人资料数据。虽然注册成功，但用户的电子邮件和密码未保存在Firebase数据库中。我也检查了规则，我使用测试模式。
这是我的规则：
{
"rules": {
".read": true,
".write": true
}
}
这是我的代码：
public class SignUpActivity extends AppCompatActivity
{
private Button btn_signin,btn_signup;
private EditText inputEmail, inputPassword, inputconPassword;
private ProgressBar progressBar;
private FirebaseAuth auth;
private FirebaseUser firebaseuser;
private static final String PASSWORD_PATTERN ="((?=.*\\d)(?=.*[a-z])(?=.*[A-Z]).{6,20})";
private static final String expression = "^[\\w\\.-]+@([\\w\\-]+\\.)+[A-Z]{2,4}$";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_sign_up);
auth = FirebaseAuth.getInstance();
btn_signin = (Button) findViewById(R.id.btn_signin);
btn_signup = (Button) findViewById(R.id.btn_signup);
inputEmail = (EditText) findViewById(R.id.u_email);
inputPassword = (EditText) findViewById(R.id.u_password);
inputconPassword = (EditText) findViewById(R.id.u_conpassword);
progressBar = (ProgressBar) findViewById(R.id.progressBar);
btn_signin.setOnClickListener(new View.OnClickListener()
{
@Override
public void onClick(View v)
{
startActivity(new Intent(SignUpActivity.this, LoginActivity.class));
}
});
btn_signup.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
final String email = inputEmail.getText().toString().trim();
final String password = inputPassword.getText().toString().trim();
if (!validateForm())
{
return;
}
progressBar.setVisibility(View.VISIBLE);
//create user
auth.createUserWithEmailAndPassword(email, password)
.addOnCompleteListener(SignUpActivity.this, new OnCompleteListener<AuthResult>() {
@Override
public void onComplete(@NonNull Task<AuthResult> task) {
progressBar.setVisibility(View.GONE);
// If sign in fails, display a message to the user. If sign in succeeds
// the auth state listener will be notified and logic to handle the
// signed in user can be handled in the listener.
if (!task.isSuccessful())
{
Toast.makeText(SignUpActivity.this, "Authentication failed." + task.getException(),
Toast.LENGTH_SHORT).show();
}
else
{
Toast.makeText(SignUpActivity.this, "createUserWithEmail:onComplete:" + task.isSuccessful(), Toast.LENGTH_SHORT).show();
firebaseuser = auth.getCurrentUser();
User myUserInsertObj = new User(inputEmail.getText().toString().trim(),inputconPassword.getText().toString().trim());
DatabaseReference ref = FirebaseDatabase.getInstance().getReference("Users");
String uid = firebaseuser.getUid();
ref.child(uid).setValue(myUserInsertObj).addOnCompleteListener(new OnCompleteListener<Void>() {
@Override

{

{
Toast.makeText(SignUpActivity.this, "User data stored.",Toast.LENGTH_SHORT).show();
finish();
startActivity(new Intent(getApplicationContext(), Main2Activity.class));
}
else
{
Toast.makeText(SignUpActivity.this, "Error.",Toast.LENGTH_SHORT).show();
finish();
startActivity(new Intent(getApplicationContext(), Main3Activity.class));
}
}
});
}
}
});
}
});
}
private boolean validateForm()
{
boolean valid = true;
String email = inputEmail.getText().toString();
if (TextUtils.isEmpty(email))
{
inputEmail.setError("Required.");
valid = false;
}

要在注册后存储用户的电子邮件和密码，请执行以下操作：
String email=inputEmail.getText().toString().trim();
String password=inputconPassword.getText().toString().trim();
FirebaseUser currentUser= task.getResult().getUser();
String userid=currentUser.getUid();
DatabaseReference ref = FirebaseDatabase.getInstance().getReference().child("Users").child(userid);
ref.child("email").setValue(email);
ref.child("password").setValue(password);
然后你会：
Users
userid
email: email_here
password: password_here

此answer可以让您更深入地了解firebase如何处理身份验证信息（电子邮件+密码）..
此类信息存储在单独的数据库中，因此如果您想存储用户数据，则必须自己完成。
您可以找到有关如何存储用户数据的here的更多详细信息。
答案 2 :(得分：0)
为什么要在Firebase中存储纯文本密码？这是一个糟糕的主意。 Firebase Auth已经对您的用户密码进行哈希处理。如果您需要迁移到外部系统，他们会通过CLI SDK和Admin SDK提供多种工具。

这是我的注册代码按钮。它似乎没有从以前的变化，但这一个有效。
btn_signup.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
final String email = inputEmail.getText().toString().trim();
final String password = inputPassword.getText().toString().trim();
if (!validateForm())
{
return;
}
progressBar.setVisibility(View.VISIBLE);
//create user
auth.createUserWithEmailAndPassword(email, password)
.addOnCompleteListener(SignUpActivity.this, new OnCompleteListener<AuthResult>() {
@Override
public void onComplete(@NonNull Task<AuthResult> task) {
progressBar.setVisibility(View.GONE);
// If sign in fails, display a message to the user. If sign in succeeds
// the auth state listener will be notified and logic to handle the
// signed in user can be handled in the listener.
if (task.isSuccessful())
{
DatabaseReference ref = FirebaseDatabase.getInstance().getReference("Users");
firebaseUser = auth.getCurrentUser();
String uid = firebaseUser.getUid();
User my = new User(email,password);
ref.child(uid).setValue(my).addOnCompleteListener(new OnCompleteListener<Void>() {
@Override
public void onComplete(@NonNull Task<Void> task)
{
if(task.isSuccessful())
{
Toast.makeText(SignUpActivity.this, "Sign Up successfully.",Toast.LENGTH_SHORT).show();
finish();
startActivity(new Intent(getApplicationContext(), Main2Activity.class));
}
else
{
Toast.makeText(SignUpActivity.this, "Error.",Toast.LENGTH_SHORT).show();
finish();
startActivity(new Intent(getApplicationContext(), Main3Activity.class));
}
}
});
}
else
{
Toast.makeText(SignUpActivity.this, "Authentication failed." + task.getException(),
Toast.LENGTH_SHORT).show();
}
}
});
}
});
