Question

当我尝试注册时，它说注册失败。经过一些调整后，这是代码的更新版本。我试图分析代码没有运气。

                Log.e("SignUpError :", task.getException().getMessage());
            }
        }
    });
}

private void LoadInGui()
{
    Input_email = (EditText) findViewById(R. id. input_email);
    Input_password = (EditText) findViewById(R. id. input_password);
    Input_confirm_password = (EditText) findViewById(R. id. input_confirm_password);
    Input_first_name = (EditText) findViewById(R. id. Input_First_Name);
    Input_last_name = (EditText) findViewById(R. id. Input_Last_Name);
    Input_phonenumber = (EditText) findViewById(R. id. input_phonenumber);

    SignUpBtn = (Button) findViewById(R. id. register_btn);
    I_Have_An_Account_Btn = (TextView) findViewById(R. id. I_Have_An_Account_Btn);

}

}

我希望程序可以注册我，并且确实存在。在此先感谢您的帮助。

Answer 1

您正在从RegisterUser()调用onCreate()方法，这就是为什么在插入任何信息之前调用此方法的原因。

因此，仅当用户单击“注册”按钮时才从RegisterUser()中删除onCreate()呼叫。

Answer 2

    Remove  RegisterUser(); from onCreate

    and try this - 

        private void doNormalLogin(String email, String password){
      FirebaseAuth mAuth = FirebaseAuth.getInstance();
            mAuth.signInWithEmailAndPassword(email, password).addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {
                @Override
                public void onComplete(@NonNull Task<AuthResult> task) {
                    if (task.isSuccessful()) {
                    Toast.makeText(RegisterActivity.this, "Registration successful", Toast.LENGTH_SHORT).show();
                    } else {
                    Toast.makeText(RegisterActivity.this, "Registration failed", Toast.LENGTH_SHORT).show();
                    }
                }
            });
        }

Make sure you added this in your app gradle dependencies  and the bottom plugin also - 

  dependencies {
      implementation fileTree(include: ['*.jar'], dir: 'libs')
      implementation 'com.google.firebase:firebase-auth:11.2.2'
      implementation 'com.google.firebase:firebase-database:11.2.2'
  }
  apply plugin: 'com.google.gms.google-services'

  And in your Project gradle -

  dependencies {
       classpath 'com.android.tools.build:gradle:3.2.1'
       classpath 'com.google.gms:google-services:4.2.0'
   }

FirebaseAuth未创建用户
