應用listfragment

Question

我正在學習如何使用ListFragment使用getview時，當它運行下面的代碼的應用程序崩潰崩潰：

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); 
} 
} 

我知道這是因爲，當getListView（）語句我刪除它，它不會崩潰...

任何幫助非常讚賞

我做的，看起來像這樣的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> 

，然後它充氣，並做了findViewById該視圖上尋找android.R.id.list，然後有我需要擺在首位的ListView我處理。代碼片段是這樣的：

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);
