data class :
	data class model(var number:Int)
    
    
    
    
    
    
Adapter Class :
    class adapter(private val listt:ArrayList<model>): RecyclerView.Adapter<adapter.ViewHolder>() {

        class ViewHolder(itemView: View) : RecyclerView.ViewHolder(itemView) {
            var text = itemView.findViewById<TextView>(R.id.text)
        }

        override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): ViewHolder {
            val inflater= LayoutInflater.from(parent.context).inflate(R.layout.fragment_item_view,parent,false)
            return ViewHolder(inflater)
        }

        override fun onBindViewHolder(holder: ViewHolder, position: Int) {
            val current = listt[position]
            holder.text.text = current.number.toString()
        }

        override fun getItemCount(): Int {
            return listt.size

    for (i in 1..10)
        num.add(model(i))

    val adapter = adapter(num)
    binding.recyclerView.adapter = adapter
    binding.recyclerView.layoutManager = LinearLayoutManager(requireContext())
