在回收者视图中从阵列列表中删除项目的例外

Question

我写了一些代码从回收者视图对象中删除物品。那是在数组列表里面 直到大小和索引相等或索引变大为止。我真的找不到问题

public void deleteSelectedItems(){
    if (selectedItemList.size() < 1)
        return;
    for(int i = 0 ; i < selectedItemList.size() ; i++){
        int index = selectedItemList.get(i) ;
        Log.e("AAA",index + "");
        guitaristsList.remove(index);
    }
    selectedItemList.clear();
    notifyDataSetChanged();

}

public void onClick(View v) {
        if (isOnActionMode) {

            if (chxDelete.isChecked())
                selectedItemList.add(getAdapterPosition());
            else
                selectedItemList.remove((Object)getAdapterPosition());

            if (onCheckboxClickListener != null)
                onCheckboxClickListener.onCheckboxCheckedChanged(selectedItemList.size());
        }

}
