onWaveInstanceState之后的TabWidget onClick(java.lang.IllegalStateException:在onSaveInstanceState之后无法执行此操作)

Question

我创建了一个片段标签控件下面的片段兼容包样品,我改变片段onTabChanged,但我有一些市场报告,斑点IllegalStateException后onSaveInstanceState,这是通过询问承诺片段经理打电话后引起的onSaveInstanceState(),但我怎么能接受performClick后onSaveInstanceStateIS叫什么名字？

堆栈跟踪:

看起来这是以某种方式讨论(通过搜索错误),但对我来说,它只是一个副作用,一个支持的错误？我还阅读了有关honey +的不同应用程序生命周期,但在保存实例后执行单击看起来对我来说是无法解决的行为

我应该使用commitAllowingStateLoss()还是 mTabHost.setOnClickListener(null)在onSaveInstanceState？

不幸的是我无法重现,我只看到关于开发者控制台的罕见报告

活动有 android:configChanges="orientation|screenLayout"

我用"总是完成"测试了生命周期

标签片段切换器在ViewPager中,但我怀疑是否相关

问题是您试图在调用's方法FragmentTransaction后提交 a 。由于本博客文章中描述的原因，这是不允许的。ActivityonSaveInstanceState()
