我在 Firebase 数据库中获取了用户，但单击注册后似乎没有打开登录活动。它不停地显示进度条...
这是 registerUser 代码块
private void registerUser(String txtFullname, String txtEmail, String txtDob, String txtGender, String txtMobile, String txtPwd) {
FirebaseAuth auth = FirebaseAuth.getInstance();
Toast.makeText(this, "TESTING", Toast.LENGTH_SHORT).show();
System.out.println("TESTING");
// Create the user with email and password
auth.createUserWithEmailAndPassword(txtEmail, txtPwd).addOnCompleteListener(RegisterActivity.this,
new OnCompleteListener<AuthResult>() {
@Override
public void onComplete(@NonNull Task<AuthResult> task) {
if (task.isSuccessful()) {
System.out.println("User registration successful");
FirebaseUser firebaseUser = auth.getCurrentUser();
// Update display name of the user
UserProfileChangeRequest profileChangeRequest = new UserProfileChangeRequest.Builder()
.setDisplayName(txtFullname).build();
firebaseUser.updateProfile(profileChangeRequest);
// Enter user data into the Firebase real-time database
ReadWriteUserDetails writeUserDetails = new ReadWriteUserDetails(txtDob, txtGender, txtMobile);
DatabaseReference referenceProfile = FirebaseDatabase.getInstance().getReference("Registered Users");
referenceProfile.child(firebaseUser.getUid()).setValue(writeUserDetails).addOnCompleteListener(new OnCompleteListener<Void>() {
@Override
public void onComplete(@NonNull Task<Void> task) {
if (task.isSuccessful()) {
System.out.println("User data saved successfully in database");
firebaseUser.sendEmailVerification().addOnCompleteListener(new OnCompleteListener<Void>() {
@Override
public void onComplete(@NonNull Task<Void> task) {
if (task.isSuccessful()) {
Toast.makeText(RegisterActivity.this, "User registered successfully. Please verify your email.", Toast.LENGTH_SHORT).show();
Intent intent = new Intent(RegisterActivity.this, LoginActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_CLEAR_TASK | Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);
finish();
} else {
System.out.println("Failed to send verification email");
Toast.makeText(RegisterActivity.this, "Failed to send verification email.", Toast.LENGTH_SHORT).show();
}
}
});
} else {
System.out.println("Failed to save user data in database");
Toast.makeText(RegisterActivity.this, "Failed to save user data.", Toast.LENGTH_SHORT).show();
}
progressBar.setVisibility(View.GONE);
}
});
} else {
try {
throw task.getException();
} catch (FirebaseAuthWeakPasswordException e) {
etRegPwd.setError("Password must contain 6 or more characters. Letters, numbers, and special character required");
etRegPwd.requestFocus();
} catch (FirebaseAuthInvalidCredentialsException e) {
etRegEmail.setError("Your email is invalid or already in use.");
etRegEmail.requestFocus();
} catch (FirebaseAuthUserCollisionException e) {
etRegEmail.setError("User is already registered.");
etRegEmail.requestFocus();

System.out.println(e.getMessage());
Toast.makeText(RegisterActivity.this, e.getMessage(), Toast.LENGTH_SHORT).show();

我希望用户单击注册后，它会打开 LoginActivity 并显示“用户数据已成功保存在数据库中”消息。
首先，我强烈建议将每个功能分离为单独的函数，例如您可以执行以下操作：
这将改善代码组织、可重用性和可维护性。
此外，我建议在用户注册成功后发送验证电子邮件，以确保用户对象有效。
您可以在这里
