我在实现一个过滤器的时候遇到了java.lang.IndexOutOfBoundsException。在onBindViewHolder方法中出现了错误，并且位置值大于过滤列表，所以它产生了indexOutOfBoundException。我不知道为什么即使我调用了notifyDataSetChanged（），位置值也大于过滤列表。这是我的一个过滤器适配器的代码。请给予我一些解决这个问题的方法。谢谢！！

class MainListAdapter(
private val context: Context,
private val item_list: MutableList<items_list>) :
RecyclerView.Adapter<MainListAdapter.ViewHolder>(),
Filterable {
var filteredList: MutableList<items_list>? = item_list
inner class ViewHolder(view: View) : RecyclerView.ViewHolder(view) {
    val Photo = view.PhotoImg
    val item_name = view.item_name
    fun bind(item: items_list, context: Context) {
        val resourceId =
            context.resources.getIdentifier(item.photo, "drawable", context.packageName)
        Photo.setImageResource(resourceId)
        item_name.text = item.item_name
    }
}
override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): ViewHolder {
    val itemView = LayoutInflater.from(context).inflate(R.layout.item, parent, false)
    return ViewHolder(itemView)
}
override fun onBindViewHolder(holder: ViewHolder, position: Int) {
    val current = filteredList?.get(position)
    if (current != null) {
        holder.bind(current, context)
    }
}
override fun getItemCount(): Int = item_list!!.size
override fun getFilter(): Filter? {
    return object : Filter() {
        override fun performFiltering(constraint: CharSequence): FilterResults {
            val charString = constraint.toString()
            filteredList = if (charString.isEmpty()) {
                item_list
            } else {
                val filteringList = ArrayList<items_list>()
                if (item_list != null) {
                    for (name in item_list) {
                        if (name.item_name.toLowerCase().contains(charString.toLowerCase())) {
                            filteringList.add(name);
                        }
                    }
                }
                filteringList
            }
            val filterResults = FilterResults()
            filterResults.values = filteredList
            return filterResults
        }
        override fun publishResults(constraint: CharSequence, results: FilterResults) {
            filteredList = results.values as ArrayList<items_list>
            notifyDataSetChanged()
        }
    }
}
