Answer 1

错误是：

Fatal Exception: java.lang.IllegalStateException: Can not perform this action after onSaveInstanceState

此错误与方法调用顺序更相关。我的意思是，你可能调用了一些方法，但是活动/片段处于无法处理该方法的状态。

这也可能是由错误时间的片段事务引起的。

这就是为什么你没有在日志中找到行号。

您可以搜索此错误，您将看到不同的根本原因。这至少可以指导您找到问题点。

请用＆＃34; onSaveInstanceState＆＃34;更新您的问题方法。这样，我们可以尝试为您提供更多帮助。
