Firebase 身份驗證 - 在控制台中創建用戶但進度條不會停止旋轉並且任務未完成？

Question

所以我正在處理移動應用程序的注冊表，當用戶填寫注冊表並提交時，進度條會出現並無限旋轉，令人驚訝的是沒有打印任何消息。 盡管如此，用戶確實出現在 Firebase 控制台中，這讓我感到不可思議。

代碼：

    progressBar.setVisibility(View.VISIBLE);
            mAuth.createUserWithEmailAndPassword(email, password)
                    .addOnCompleteListener(new OnCompleteListener<AuthResult>() {
                        @Override
                        public void onComplete(@NonNull Task<AuthResult> task) {
                            if(task.isSuccessful()) {
                                User user = new User(fullName, rating, email);
    
                                System.out.println(user.fullName);
    
                                FirebaseDatabase.getInstance().getReference("Users")
                                        .child(FirebaseAuth.getInstance().getCurrentUser().getUid())
                                        .setValue(user).addOnCompleteListener(new OnCompleteListener<Void>() {
                                    @Override
                                    public void onComplete(@NonNull Task<Void> task) {
                                        if(task.isSuccessful()) {
                                            Toast.makeText(RegisterUser.this, "User has been registered succesfully!", Toast.LENGTH_LONG).show();
System.out.println("Success!");
                                            progressBar.setVisibility(View.GONE);
                                        }else {
                                            Toast.makeText(RegisterUser.this, "Failed to register! 
 Try again!", Toast.LENGTH_LONG).show();
System.out.println("Failure!");
                                            progressBar.setVisibility(View.GONE);
                                        }
                                    }
                                });
                            }
                        }
                    });

謝謝！

    FirebaseDatabase.getInstance().getReference("Users")
                                            .child(FirebaseAuth.getInstance().getCurrentUser().getUid())
                                            .setValue(user).addOnCompleteListener(new OnCompleteListener<Void>() {
                                        @Override
                                        public void onComplete(@NonNull Task<Void> task) {
                                            if(task.isSuccessful()) {
                                                Toast.makeText(RegisterUser.this, "User has been registered succesfully!", Toast.LENGTH_LONG).show();
    System.out.println("Success!");
                                                progressBar.setVisibility(View.GONE);
                                            }else {
                                                Toast.makeText(RegisterUser.this, "Failed to register! 
     Try again!", Toast.LENGTH_LONG).show();
    System.out.println("Failure!");
                                                progressBar.setVisibility(View.GONE);
                                            }
                                        }
                                    }).addOnFailureListener(new OnFailureListener() {
        @Override
        public void onFailure(@NonNull Exception e) {
 progressBar.setVisibility(View.GONE)
        }
    });

添加此失敗偵聽器。 所以你可以得到失敗的消息或做你想做的事。
