Android 解析未接收的对象

我从以前的活动中获取解析对象的Id，并将其存储在obj中 我知道Id是通过检查传递的，但是我得到了空指针异常，因为我的四个字符串restName、restAddress、restcoine和restLocation是空的，即使在我尝试通过解析查询分配相应的值之后也是空的

最初，我将nothing值添加到所有字符串以进行调试。当快速运行时，会打印nothing，表示查询没有对我的字符串进行任何更改。有什么建议吗？

您是否初始化了解析？e、 g Parse.initializethis，Init.Parse_APPLICATION_ID，Init.Parse_CLIENT_ID；PushService.setDefaultPushCallbackthis，Splash.class；ParseInstallation.getCurrentInstallation；是的，我有，解析调用似乎在另一个活动中工作，而不是在这个活动中。我越来越好奇，我是否使用了正确的目标尝试了你的建议，但它没有解决我的问题。还有其他建议吗？第一个问题，您是否更新了PARSE SDK？或者创建一个扩展应用程序的类。第二，解析中的列Lat和Long的类型是什么？
