ListViewアイテム クリック イベントに対して次のコードを記述しましたが、アプリケーションを実行してアイテムをクリックしても何もアクションがありません。なぜこうなった？
public class ListingActivity extends Activity implements OnClickListener{
private ListView list;
private Button sortBtn,filter;
double destLat,destLng;
AlertDialog alert;
MyAdabpter adapter;
ArrayList<HashMap<String,String>> filteredList;
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.listviewer);
list = (ListView) findViewById(R.id.list);
sortBtn = (Button) findViewById(R.id.sort_btn);
filter = (Button) findViewById(R.id.filter_btn);
// ListAdapter adapter = new SimpleAdapter(this, FetchXMLData.mylist , R.layout.list_item,
// new String[] { "Name", "Vicinity","Distance","Rating"},
// new int[] { R.id.name, R.id.address,R.id.distance,R.id.rating });
adapter = new MyAdabpter(this);
list.setAdapter(adapter);
list.setTextFilterEnabled(true);
list.setEnabled(true);
list.setOnItemClickListener(new OnItemClickListener() {

long arg3) {
