Android 从RecyclerView中取消选中复选框时删除所选项目id和值

我有一个带有复选框的RecyclerView，数据通过Web服务填充。选中复选框后，我可以获得所选的值。但当我取消选中复选框时，应用程序崩溃。我得到的异常是索引越界异常索引：8，大小：2

这是recyclerview适配器类onBindViewHolder方法。这里items是包含值的列表对象

PhysicianSpinnerAdapter countrySpinnerViewHolder = (PhysicianSpinnerAdapter) holder;
    PopulateDoctorSpecializationListItem populateCountryListItem = items.get(position);
    countrySpinnerViewHolder.binding.spinnerItem.setText(populateCountryListItem.getsName());
    countrySpinnerViewHolder.binding.checkItem.setId(populateCountryListItem.getId());
    countrySpinnerViewHolder.binding.checkItem.setChecked(items.get(position).isSelected);
    countrySpinnerViewHolder.binding.checkItem.setTag(items.get(position));
    countrySpinnerViewHolder.binding.checkItem.setOnClickListener(v -> {
        CheckBox checkBox = (CheckBox) v;
        PopulateDoctorSpecializationListItem absentListItem = (PopulateDoctorSpecializationListItem) checkBox.getTag();
        absentListItem.setSelected(checkBox.isChecked());
        if (((PhysicianSpinnerAdapter) holder).binding.checkItem.isChecked()) {
            items.get(position).setSelected(checkBox.isChecked());
            onItemClick.onItemCheck(populateCountryListItem);
        } else {
            onItemClick.onItemUnCheck(populateCountryListItem);
        }
    });

这是它在Activity类中的实现。问题发生在检查方法中

                @Override
                public void onItemCheck(PopulateDoctorSpecializationListItem spinnerItems) {
                    selectedItems.add(spinnerItems.getsName());
                    Log.d(TAG, spinnerItems.getsName());
                    selectedItemID.add(spinnerItems.getId());
                }

                @Override
                public void onItemUnCheck(PopulateDoctorSpecializationListItem spinnerItems) {
                    for (PopulateDoctorSpecializationListItem items : doctorSpecializationListItem) {
                        selectedItems.remove(items.getsName());
                        selectedItemID.remove(items.getId());
                        /*for (int i = 0; i < spinnerItems.size(); i++) {
                            selectedItemID.remove(i);
                        }*/
                    }
                }

public void onItemCheck（已填充的八月份专用列表项spinnerItems）{
