我在我的应用程序中使用ListFragment并且我想使它为列表中的每个项目都有一个OnItemClick侦听器但是当我添加ListVIEw时lv = getListVIEw();我收到一个错误.如果我删除了ListvIEw的工作但是那时我的应用程序将不需要onclick监听器.

以下是我的代码

@OverrIDepublic VIEw onCreateVIEw(LayoutInflater inflater, VIEwGroup container,        Bundle savedInstanceState) {    // Todo auto-generated method stub    ArrayList<HashMap<String, String>> menuItems = new ArrayList<HashMap<String, String>>();//...           listadapter adapter = new SimpleAdapter(getActivity(), menuItems,            R.layout.List_item,            new String[] { KEY_name, KEY_DESC, KEY_COST }, new int[] {                    R.ID.name, R.ID.desciption, R.ID.cost });    setlistadapter(adapter);    ListVIEw lv = getListVIEw();//HERE IS WHERE I AM GETTING THE ERROR    lv.setonItemClickListener(new OnItemClickListener() {        @OverrIDe        public voID onItemClick(AdapterVIEw<?> parent, VIEw vIEw,                int position, long ID) {            // getting values from selected ListItem            String name = ((TextVIEw) vIEw.findVIEwByID(R.ID.name)).getText().toString();            String cost = ((TextVIEw) vIEw.findVIEwByID(R.ID.cost)).getText().toString();            String description = ((TextVIEw) vIEw.findVIEwByID(R.ID.desciption)).getText().toString();            // Starting new intent            Intent in = new Intent(getActivity().getApplicationContext(), SingleMenuItemActivity.class);            in.putExtra(KEY_name, name);            in.putExtra(KEY_COST, cost);            in.putExtra(KEY_DESC, description);            startActivity(in);        }    });    return super.onCreateVIEw(inflater, container, savedInstanceState);}

解决方法:

在使用之前,您需要打开视图.

@OverrIDe    public VIEw onCreateVIEw(LayoutInflater inflater, VIEwGroup container,            Bundle savedInstanceState) {        v = inflater.inflate(R.layout.List, container, false);            // Set adapter etc        return v;    }

布局List.xml

<?xml version="1.0" enCoding="utf-8"?><relativeLayout xmlns:androID="http://schemas.androID.com/apk/res/androID"    androID:layout_wIDth="match_parent"    androID:layout_height="match_parent"    androID:paddingleft="2dp"    androID:paddingRight="2dp" >    <ListVIEw        androID:ID="@ID/androID:List"        androID:layout_wIDth="match_parent"        androID:layout_height="match_parent"        androID:drawSelectorOntop="false" />    <Progressbar        androID:ID="@ID/androID:empty"                androID:layout_wIDth="wrap_content"        androID:layout_height="wrap_content"        androID:layout_centerInParent="true"         /></relativeLayout>

使用onListItemClick：

@OverrIDepublic voID onListItemClick(ListVIEw l, VIEw v, int position, long ID) {  //Responding to clicks}
