Question

我正在为复选框做功能，并且在检查状态下可以正常工作，但是当我取消选中该复选框时会出现错误，还有一件事：当我选中该复选框时，我会将该项的ID存储在arraylist中并且我想在取消选中该复选框时删除该ID。

这是错误：

   java.lang.IndexOutOfBoundsException: Index: 5, Size: 5

代码：

public class ListprofileAdapter extends ArrayAdapter<PROFILE_CALL_POJO>  {
private List<PROFILE_CALL_POJO> heroList;
private Context mCtx;
Button texthideName;
FragmentTransaction fragmentTransaction;

public static ArrayList<String> proUseritems = new ArrayList<String>();

public ListprofileAdapter(ArrayList<PROFILE_CALL_POJO> profile_list, Context context) {
    super(context, R.layout.commonportal_item, profile_list);
    this.heroList = profile_list;
    this.mCtx = context;
}

@Override
public View getView(final int position, View convertView, ViewGroup parent) {
    LayoutInflater inflater = LayoutInflater.from(mCtx);
    final View listViewItem = inflater.inflate(R.layout.listcustome_item, null, true);
    final TextView textViewName = listViewItem.findViewById(R.id.portal_item);
    final CheckBox checkBox = listViewItem.findViewById(R.id.edit);


    checkBox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
        @Override
        public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
            if (buttonView.isChecked() ) {
                ListprofileAdapter.proUseritems.add(String.valueOf(heroList.get(position).getProfile_id(position)));
                Toast.makeText(mCtx, "" + proUseritems.toString(), Toast.LENGTH_SHORT).show();
            }
            else {



                ListprofileAdapter.proUseritems.remove(position);
                    Toast.makeText(mCtx, "" + proUseritems, Toast.LENGTH_SHORT).show();

             }
        }
    });

Answer 1

尝试更换：

proUseritems.remove(position);

具有：

proUseritems.remove(String.valueOf(heroList.get(position).getProfile_id(position)))

取消选中复选框不会从arraylist中删除ID
