在Rotate上的ListFragment"尚未创建的内容视图"

Question

我有一个扩展的ListFragment,这个onViewCreated()

public void onViewCreated(View v,Bundle savedInstanceState) {
    super.onViewCreated(v, savedInstanceState);
    mListener.onFragmentAction(0x000A);
    if (mAdapter != null) {
        getListView().setAdapter(mAdapter);
    }
}

mListener.onFragmentAction调用main活动来附加一些侦听器并将适配器发送到片段的listView(logFrag是活动的引用MyListFragment)

public void populateLogFrag() {
//line 225  logFrag.getListView().setOnItemLongClickListener(myEventListener);
            logFrag.getListView().setOnItemClickListener(myEventListener);
            refreshLogAdapter(provideLogAdapter());
}

应用程序加载正常,但在配置更改(设备旋转)后,我得到以下堆栈跟踪:

11-22 14:58:24.336: E/AndroidRuntime(22261): Caused by: java.lang.IllegalStateException: Content view not yet created

11-22 14:58:24.336: E/AndroidRuntime(22261):    at com.berrmal.timetracker.MyListFragment.onViewCreated(MyListFragment.java:23)

我无法弄清楚为什么还没有创建ListView,因为我在片段的onCreateView方法已经返回之后以及在onViewCreated()期间调用它.我发现了一个或两个相关标题的线程,但解决方案似乎并不适用于此.

将代码onViewCreated移至onActivityCreated.通常,使用UI小部件的所有内容都应该在onActivityCreated.
