我使用的是序列化的类我保存XML解析器的结果，但是当我看到，这是很慢的Andr​​oid，我改parcelable类。

I was using a serializable class for I save the xml parser result, but when I read that It is very slow in Android, I changed to parcelable class.

现在，我想的内容parcelable类保存到文件中。

Now, I want to save the content parcelable class into file.

我该怎么办呢？

感谢。问候。

推荐答案

根据包裹API参考

包裹的是不是一个通用的序列化机制。这个类   （和相应的API Parcelable放置任意对象   成包）被设计成一个高性能的IPC传输。如   这样，这是不恰当放置任何包裹数据在持久性   存储：变化中的任何数据的底层实现   在包裹可以使较旧的数据无法读取。

Parcel is not a general-purpose serialization mechanism. This class (and the corresponding Parcelable API for placing arbitrary objects into a Parcel) is designed as a high-performance IPC transport. As such, it is not appropriate to place any Parcel data in to persistent storage: changes in the underlying implementation of any of the data in the Parcel can render older data unreadable.

Parcelable 是为 IPC 只使用，不用于被持久化。所以，你必须将你的对象转换成某种持久化数据结构，如 XML ， JSON ，序列化。

Parcelable is meant for IPC use only and is not designed to be persisted. So you have to convert your object into some sort of persistable data structures like XML, JSON, Serializable.
