Question

我对为什么会这样感到困惑。

我想在注册活动中更新我的用户个人资料，一切正常，并且数据库已更新，直到我将firebaseAuth.signOut（）添加到sendUserData（）函数。有人遇到过这个问题吗？

                            }
                            else{
                                Toast.makeText(RegisterActivity.this, "Registration failed", Toast.LENGTH_SHORT).show();
                            }
                        }

                }

        logButton.setOnClickListener(new View.OnClickListener() {

        });
    }

    private void setupUIViews(){
        userName = (EditText)findViewById(R.id.etUser2);
        userPassword = (EditText)findViewById(R.id.etPas2);
        userEmail = (EditText)findViewById(R.id.etEmail2);
        phoneNumber = (EditText)findViewById(R.id.etPhone1);
        regButton = (Button)findViewById(R.id.registerButton2);
        logButton = (Button)findViewById(R.id.loginButton2);

    }

    private Boolean validate(){
        Boolean result = false;

         name = userName.getText().toString();
         email = userEmail.getText().toString();
         phone = phoneNumber.getText().toString();
         password = userPassword.getText().toString();

        if(name.isEmpty() || password.isEmpty() || email.isEmpty()){
           Toast.makeText(this, "Please enter all the details", Toast.LENGTH_SHORT).show();
        }
        else{
            result = true;
        }
        return result;
    }

    private void sendEmailVerification(){
        final FirebaseUser firebaseUser = firebaseAuth.getInstance().getCurrentUser();

        if(firebaseUser != null){
            firebaseUser.sendEmailVerification().addOnCompleteListener(new OnCompleteListener<Void>() {
                @Override
                public void onComplete(@NonNull Task<Void> task) {
                    if(task.isSuccessful()){
                        sendUserData();
                        Toast.makeText(RegisterActivity.this, "Sucessfully registered", Toast.LENGTH_SHORT).show();
 //---------------->>>//firebaseAuth.signOut();//<<<-----------//
                        finish();
                        startActivity(new Intent(RegisterActivity.this, MainActivity.class));
                    }
                    else{
                        Toast.makeText(RegisterActivity.this, "Verification email was not sent", Toast.LENGTH_SHORT).show();
                    }
                }
            });
        }
    }

    private void sendUserData(){
        FirebaseDatabase firebaseDatabase = FirebaseDatabase.getInstance();
        DatabaseReference myRef = firebaseDatabase.getReference(firebaseAuth.getUid());
        UserProfile userProfile = new UserProfile(name, email, phone);

        Toast.makeText(RegisterActivity.this, "User data was sent to the database" + firebaseDatabase.toString(), Toast.LENGTH_SHORT).show();

        myRef.setValue(userProfile).addOnSuccessListener(new OnSuccessListener<Void>() {
            @Override
            public void onSuccess(Void aVoid) {
                firebaseAuth.signOut();
            }
        });
    }
}

因此数据库可以正常运行（数据通过firebase被上载到实时数据库中）而无需注销，但是我遇到的问题是用户自动登录到UserProfileActivity中。

请提供错误跟踪信息或错误信息，以便我们了解发生了什么。顺便说一句，您的吐司应该显示在onSuccessListener（）内。在检查任务是否成功之前，您正在显示吐司

如果调用了firebaseAuth.signOut（），则无法发送用户数据
