我正试图在CheckBox ListView中使用ArrayAdapter。当我在列表中选择任何CheckBox onlytime时，会以随机顺序自动选择多个条目。任何人都可以告诉我如何避免这种情况。
以下是我的代码供您参考：
public class SearchListAdapterQ2扩展了BaseAdapter {
int layoutId;
ArrayList<SearchListView> searchresultList = new ArrayList<SearchListView>();
public static int companyCpsId;
public static String companyCpsType = "", search_companyName = "",
search_countryName = "", handShakeStatus = "";
public static String handShakeCPSName = "";
public static boolean searchListAdapter_Q2 = false;
SharedPreferences sharedpreferences;
boolean markfavStatus = false;
ListView searchResults_listView;
Context context;
public SearchListAdapterQ2(Context context, int layoutId,
ArrayList<SearchListView> searchresultList,
ListView searchResults_listView) {
// TODO Auto-generated constructor stub
this.layoutId = layoutId;
this.searchresultList = searchresultList;
Log.i("inside searchListAdapter", "inside searchListAdapter");
this.context = context;
sharedpreferences = context.getSharedPreferences("MyPrefs",
Context.MODE_PRIVATE);
this.searchResults_listView = searchResults_listView;
}
@Override
public int getCount() {
// TODO Auto-generated method stub
Log.i("searchresultList",
"searchresultList: " + searchresultList.size());
return searchresultList.size();
}
@Override
public Object getItem(int position) {
// TODO Auto-generated method stub
return searchresultList.get(position);
}
@Override

在您的适配器中getView（）方法设置模型中单击复选框的状态并调用通知数据集更改，试试

我在代码中添加了以下行，它开始正常工作：
ArrayList<Integer> checkedPositions = new ArrayList<Integer>();
final Integer index = new Integer(position);
holder1.chckbx1.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
if (((CheckBox) v).isChecked()) {
// if checked, we add it to the list
checkedPositions.add(index);
} else if (checkedPositions.contains(index)) {
// else if remove it from the list (if it is present)
checkedPositions.remove(index);
}
}
});
// set the state of the checbox based on if it is checked or not.
holder1.chckbx1.setChecked(checkedPositions.contains(index));
