AndroidX：Parcelable 遇到 IOException，仅在 Android 版本 10 设备中写入可序列化对象

Question

我得到了Parcelable encountered IOException writing serializable object它，它java.io.NotSerializableException: androidx.appcompat.widget.Toolbar仅由Android 版本 10 设备中的错误引起。

我已经搜索了很多结果来获得这个问题的解决方案，但我得到的每个解决方案都告诉implement serializable在内部类和子内部类中定义 ，我已经做到了，但我只在 Android 10 版设备中遇到了这个错误。

如果我将使用transient此关键字来定义视图或对象，则此错误将得到解决，但此错误会伴随另一个视图、适配器和类。
