＆QUOT;不能执行及的onSaveInstanceState后QUOT这个动作; - 为什么我越来越从我的活动的onResume方法，这个异常？ [英] "Can not perform this action after onSaveInstanceState" - why am I getting this exception from my activity's onResume method?

问题描述

我的活动调用与ACTION_IM​​AGE_CAPTURE意图相机。如果相机活动成功地返回，我在回调的onActivityResult设置一个标志，并根据标志的值，我开始一个片段在我onResume一个标题添加到被拍摄的图像。这似乎工作确定。

My activity invokes the camera with the ACTION_IMAGE_CAPTURE intent. If the camera activity returns succesfully, I set a flag in the onActivityResult callback, and based on the value of the flag I start a fragment in my onResume to add a caption to the image that was captured. This seems to work ok.

我刚刚得到一个堆栈跟踪从野抱怨说我是想的onSaveInstanceState被称为后提交片段事务。但我在做我的onResume方法提交！为什么会抱怨的android这个？我有的android：configChanges =方向| keyboardHidden |键盘|屏幕尺寸在我的Andr​​oidManifest.xml中设定，所以改变方向时，不应触发这个....

I just got a stack trace from the "wild" complaining that I was trying to commit a fragment transaction after onSaveInstanceState has been called. But I'm doing the commit in my onResume method! Why would android complain about this? I do have android:configChanges="orientation|keyboardHidden|keyboard|screenSize" set in my AndroidManifest.xml, so an orientation change should not trigger this....

推荐答案

我觉得我知道答案 - 我用从V4兼容库的FragmentActivity，所以我需要执行我的片段交易onResumeFragments而不是在onResume。有人可以证实？

I think I know the answer - I'm using the FragmentActivity from v4 compatibility library, and so I need to perform my fragment transactions in onResumeFragments instead of in onResume. Can someone confirm?
