我不知道如何复制这一点，但看看stacktrace，它似乎是在应用程序停止时发生的。

我真的不明白为什么android试图序列化/打包我的片段，我没有在任何地方实现onSaveInstanceState/onRestoreInstanceState。

谁能帮帮我吗？

谢谢，卢卡

编辑：谢谢你的回答。不，我没有任何视图的自定义输入，

可能是解决此错误的方法，重写上SaveInstanceState而不调用suoer.onSaveInstanceState？

Answer 1

来自官方文件

默认实现通过在层次结构中具有id的每个视图上调用onSaveInstanceState（），并通过保存当前聚焦视图的id（所有这些都由onRestoreInstanceState（Bundle）的默认实现恢复），为您处理大部分UI每个实例状态。

您是否有自定义视图实现，或者使用新字段扩展基础视图，并在片段中使用它？
