AndroidX:仅在Android版本10设备中，Parcelable遇到IOException编写可序列化对象 [英] AndroidX : Parcelable encountered IOException writing serializable object only in Android version 10 devices
本文介绍了AndroidX:仅在Android版本10设备中，Parcelable遇到IOException编写可序列化对象的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我得到了Parcelable encountered IOException writing serializable object，它是仅在Android版本10设备中由java.io.NotSerializableException: androidx.appcompat.widget.Toolbar错误引起的.
I got Parcelable encountered IOException writing serializable object and it caused by java.io.NotSerializableException: androidx.appcompat.widget.Toolbar error only in Android Version 10 devices.
我搜索了很多结果来找到该问题的解决方案，但是我得到的每个解决方案都要求在内部类和内部子类中定义implement serializable而且我已经做到了，但仅在Android版本10设备上才出现此错误.
I've searched many results for getting solutions to this problem but every solution I got, was telling to define implement serializable in both inner class and sub inner class and I've done it, still, I got this error only in Android version 10 devices.
如果我将使用transient这个关键字定义视图"或对象"，则此错误将得到解决，但是另一个视图，适配器和类也会出现此错误.
If I will use transient this keyword to define View or object then this error will fix but this same error comes with another view, adapter, and class.

推荐答案
看起来像在代码中的某个地方，您正在尝试编写整个Fragment(看起来是CustomViewFragment)以进行包裹:
Looks like somewhere in your code, you are trying to write a whole Fragment (looks like it is CustomViewFragment) to parcel:
java.lang.RuntimeException: Parcelable encountered IOException writing serializable object (name = com.android.ui.fragment.CustomViewFragment)
要可序列化您的类及其所有成员，必须实现Serializable.因为Fragment的上下文是Activity(可能是BaseFragmentActivity的子类)，所以它也要经历序列化过程.但是Fragment和Activity都没有实现Serializable接口.
To be serializable your class and all its members have to implement Serializable. Because Fragment's context is Activity (that is probably a subclass of BaseFragmentActivity) it also goes through the process of serialization. But neither Fragment nor Activity implements Serializable interface.
