推荐答案

这可能是你的问题：

类实现Parcelable接口还必须有一个静态字段名为 CREATOR ，这是实现一个目标的 Parcelable.Creator 接口。

Classes implementing the Parcelable interface must also have a static field called CREATOR, which is an object implementing the Parcelable.Creator interface.

另外，我想尝试有项目实施 Parcelable ，以及

Alternatively, I'd try to have Item implement Parcelable, as well.

故障安全的替代方法是写你的数据结构成JSON字符串，这也可以让你通过数据没有访问您的 ParsedData 类。

The fail-safe alternative is to write your data structure into a JSON string, which also allows you to pass the data to other applications that don't have access to your ParsedData class.
