Onclick в переработчикеПросмотреть неправильные позиции

Question

У меня есть recyclerView с 10 именами и в этом activity возможен поиск по имени. При щелчке по имени activity перемещается в другое (с помощью Intents для перемещения по DetailsActivity). Это возможно сделать, потому что в адаптере у меня есть функция, которая задает позицию, на которую нажал пользователь. Но при вводе слова в меню поиска этот функционал дает позицию 1 (реальная позиция имени, в настоящий момент). Я могу отправить в функцию в adpter, например, идентификатор имени? Как правильно это сделать?

    override fun getItemCount(): Int {
        return listDataPeople.size
    }

    override fun onBindViewHolder(holder: RecyclerView.ViewHolder, position: Int) {

    interface OnNoteListener {
        fun onNoteClick(position: Int)

    init {

Answer 1

Вы должны отправить position на ViewHolder .

override fun onBindViewHolder(holder: RecyclerView.ViewHolder, position: Int) {
    when (holder) {
        is ViewHolder -> {
            holder.ViewHolder(listDataPeople[position], mOnNoteListener,position)
        }
    }
}

Затем передать это значение в onNoteClick ()

fun ViewHolder(dataPeople: DataPeople, onNoteListener: OnNoteListener,position: Int) {
        val name = dataPeople.name
        this.textViewName.text = name
        this.onNoteListener = onNoteListener
        itemView.setOnClickListener(this)
    }

    override fun onClick(v: View?) {
        onNoteListener?.onNoteClick(position)
    }
