Как работает нумерация строк в таблице при использовании kotlin

Question

Я устанавливаю базу данных в виде базы данных firebase с помощью recyclerView, используя kotlin Я хочу работать с нумерацией строк в tableVieew

 override fun onBindViewHolder(p0: ViewHolder, p1: Int) {
    val recyclerView1 = listAdapter[p1]
    p0.name.text = recyclerView1.name
    p0.numbringRow = here I want code
    p0.scoreVaule.text = recyclerView1.scoreVaule.toString()
    Picasso.get().load(recyclerView1.profileImageurl).into(p0.imageView)
}

Я хочу нумерацию и сортировку по большому номеру

val RV4 =  findViewById(R.id.recyclerView3) as RecyclerView
    RV4.layoutManager = LinearLayoutManager(this, LinearLayout.VERTICAL, false)

    val Recycler33 = ArrayList<ListCellForLeaderBoard>()

    ref.child("Score").orderByChild("scoreVaule").limitToLast(200).addValueEventListener(object : ValueEventListener {

        override fun onCancelled(p0: DatabaseError) {

        }
        override fun onDataChange(dataSnapshot: DataSnapshot) {
            try{
                val td = dataSnapshot.value as HashMap<String,Any>
                Recycler33.clear()
                for (q2 in td.keys){
                    val data = td[q2] as HashMap<String,Any>
                    Recycler33.add(ListCellForLeaderBoard(
                            data["name"] as String?,
                            data["profileImageurl"] as String?,
                            data["scoreVaule"] as Long?
                    ))

                }
                val adapter3 = RecyclerViewAdapterLeaderBoard(Recycler33)

                RV4.adapter = adapter3
            }catch (ex:Exception){
                println("It is not found")
            }
        }})
