使用list fragment中的getView时应用程序崩溃

Question

我正在学习如何使用list fragment，并且在运行以下代码时该应用程序正在崩溃：

public class profileListFragment extends ListFragment {
String[] countries = new String[] {"USA", "China"};
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    getListView().setChoiceMode(ListView.CHOICE_MODE_SINGLE);
    ArrayAdapter<String> adapter = new ArrayAdapter<String>(inflater.getContext(),
            android.R.layout.simple_list_item_1,countries);
    setListAdapter(adapter);
    View retView = super.onCreateView(inflater, container,  savedInstanceState);
    return retView;//super.onCreateView(inflater, container,  savedInstanceState);
}
public void onListItemClick(ListView I, View v, int position, long id){
    I.setChoiceMode(ListView.CHOICE_MODE_SINGLE);
    I.setSelector(android.R.color.holo_blue_light);
}
}

我知道这是因为getListView（）语句，因为当我删除它不会崩溃...

任何帮助都非常感谢

我做了一个看起来像这样的XML：

 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
     android:orientation="vertical"
     android:layout_width="match_parent"
     android:layout_height="match_parent" >
<ListView
    android:id="@id/android:list"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:choiceMode="singleChoice" >
</ListView>
</LinearLayout>

然后将其充气，然后在该视图上进行findViewByid，以查找Android.r.id.list，然后首先要使用我需要的ListView处理程序。代码段是这样：

    View retView = inflater.inflate(R.layout.fragment_load_profile_list_layout,container, false);
    ListView lv = (ListView) retView.findViewById(android.R.id.list);
    lv.setSelector(android.R.color.holo_blue_light);
    lv.setChoiceMode(ListView.CHOICE_MODE_SINGLE);
