setItemChecked（）不起作用

Question

  String[] mListContent={"Sunday", "Monday", "Tuesday", "Wedneday", "Thursday", "Friday", "Saturday"};
  setListAdapter( new AlarmDaysAdapter(this, android.R.layout.simple_list_item_checked, mListContent));
  ListView listView = getListView();
  listView.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);      
  for(ii=0; ii<values.size(); ii++)
  {
      listView.setItemChecked(values.get(ii),true);
      Log.i(" values: " + values.get(ii)," ");
  }

我想在显示Listview时检查一些列表项。 Log.i打印values.get(ii)中存在的完美值，这是我想要默认检查的位置。我怎样才能实现它？
