问题描述
我遇到了一个问题，我有多个片段的活动。对于任何个别片段，您可以执行搜索操作，其工作就好了... ...如果你从任何一个片段进行搜索，它会显示一个新的活动来处理搜索，然后将结果返回给活动处理显示新片段。问题是，搜索操作后，我希望能够以清除（几乎）所有的碎片远用 popBackStackImmediate（...），自 saveInstanceState（...）叫，我得到一个说异常：
I'm running into an issue where I have an Activity with multiple fragments. For any individual fragment, you can perform a search operation, which works just fine...if you search from any of the fragments, it will display a new Activity to handle the searching, then return the result to the Activity to handle displaying a new fragment. The problem is, after a search operation, I want to be able to clear (almost) all the fragments away using popBackStackImmediate(...) and since saveInstanceState(...) was called, I get an exception that says:
"java.lang.IllegalStateException: Can not perform this action after onSaveInstanceState"
不知道如何从后面栈中弹出后的onSaveInstanceState 被称为？
推荐答案
显然，我的问题从的onActivityResult（...）
Apparently my issue spawned from the call being made in onActivityResult(...)
我能够通过把里面一个Runnable的UI修改code，然后发布了Runnable主线程来解决这个问题：
I was able to fix the issue by putting the UI modification code inside a Runnable, then posting the Runnable to the main thread:
Runnable r = new Runnable() {
@Override
public void run() {
// UI code here
}
};
Handler h = new Handler();
h.post(r);
这篇关于popBackStack（）saveInstanceState后（）的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
