android–java.lang.ClassCastException：com.parse.ParseObject无法强制转换为

概述我创建了2个类(Meal,Restaurant),它们扩展了ParseObject,并创建了2个自定义适配器(BottomFragmentMealAdapter,RestaurantAdapter).我尝试在BottomFragmentMealAdapter(它可以)为RestaurantAdapter做任何事情.但它不起作用.这是我的日志：FATALEXCEPTION:main

我创建了2个类(Meal,Restaurant),它们扩展了ParSEObject,并创建了2个自定义适配器(BottomFragmentMealAdapter,RestaurantAdapter).我尝试在BottomFragmentMealAdapter(它可以)为RestaurantAdapter做任何事情.但它不起作用.
这是我的日志：

解决方法:

你必须检查两件事

>确保您的子类具有公共默认值(即零参数)构造函数.您不得修改此构造函数中的任何ParSEObject字段.
和
>在调用Parse.initialize()之前,在Application构造函数中调用ParSEObject.registerSubclass(YourClass.class).
