UnsupportedOperationException-OnCheckedChanged

Question

我试图在RecyclerView中选择和删除类别，但某些特定的手机品牌（Android版本8或9）出现UnsupportedOperationException。

我的代码：

holder.checkBox.setOnCheckedChangeListener { _, isChecked ->

        if (isChecked){
            mListener.onItemSelected(position,true)  //CategoryAdapter.kt:42
            mSelectedItems.add(position)
        }else{
            mListener.onItemSelected(position,false)
            mSelectedItems.remove(position)
        }
        //notifyDataSetChanged()
    }
//
//

private var categoriesDefault = mutableListOf<String>()

override fun onItemSelected(position: Int, isSelected: Boolean) {
    if (isSelected){
        categoriesDefault.add(categoriesValues[position]) //CategoryFragment.kt:19
    }else{
        categoriesDefault.remove(categoriesValues[position])
    }

    tinyDB.categories = categoriesDefault
}
