How to get data recycleview to parse on other updateactivity? - android-recyclerview

Question

I have code in ListBukpotAdapter, how can I get data listener.OnClick(currentItem) to parse on other UpdateActivity
Error:
kotlin.UnitializedPropertyAccessExeption: lateinit property listener has not been initialized
class ListBukpotAdapter : RecyclerView.Adapter<ListBukpotAdapter.MyViewHolder>() {
private var bukpotList = emptyList<QrResultBukpot>()
private lateinit var listener: OnAdapterListener
interface OnAdapterListener {
fun OnClick(bukpotDataParsing: QrResultBukpot)
}
class MyViewHolder(itemView: View): RecyclerView.ViewHolder(itemView) {}
override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): MyViewHolder {
return MyViewHolder(LayoutInflater.from(parent.context).inflate(R.layout.custom_row_bukpot, parent, false))
}
override fun getItemCount(): Int {
return bukpotList.size
}
override fun onBindViewHolder(holder: MyViewHolder, position: Int) {
val currentItem = bukpotList[position]
holder.itemView.txtNomorBukpot.text = currentItem.nomorBukpot
holder.itemView.txtNpwpPemotong.text = currentItem.npwpPemotong
holder.itemView.txtMasaPajak.text = currentItem.masaPajak + " / " + currentItem.tahunPajak
holder.itemView.txtMixCode.text = currentItem.mixCode
holder.itemView.rowLayoutBukpot.setOnClickListener {
listener.OnClick(currentItem)
val context = holder.itemView.context
val intent = Intent(context, UpdateBukpotActivity::class.java)
context.startActivity(intent)
}
}
fun setDataBukpot(bukpot: List<QrResultBukpot>){
this.bukpotList = bukpot
notifyDataSetChanged()
}
}

You should initilaze your listener. Your listener variable is lateinit so before you use this, you need to initialize. You can give listener as a constructor parameter from your activity or fragment and can listen interface from your activity or fragment which contains recyclerview.
