Question

我正在我的Android应用程序中创建一个登录/注册活动。当用户注册时，Firebase身份验证工作正常。注册后，使用将直接进入设置活动。现在，设置活动是将数据存储到Firebase数据库中。每当用户完成设置并单击按钮以更新数据库时。该应用程序停止运行。

private Button SaveInformation;
 SaveInformation.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view)
            {
                SaveAccountSetupInformation();
            }
        });

When the app is crashing the logcat is showing this error

enter image description here

The App is showing this error

我的设置活动代码为：

Answer 1

您在logcat中显示的错误是

 Found conflicting getters for name: getText

Firebase数据库只能存储JSON类型，但是您向其发送了一个“编辑文本” 错误恰好在这里

  userMap.put("day",Day);
        userMap.put("month",Month);
        userMap.put("year",Year);
  userMap.put("state",State);

您将“天，月，年和状态”发送为“编辑文本”而不是字符串像这样

  userMap.put("day",day);
        userMap.put("month",month);
        userMap.put("year",year);
   userMap.put("state",state);

它将正常工作

每当我在该SetupActivity中单击“保存”按钮时，我的应用就会崩溃。每当我要在Firebase数据库中写入时，我的应用程序崩溃
