RecyclerView Adapter:
class RecyclerViewAdapter(private val items: List<String>) : RecyclerView.Adapter<RecyclerViewAdapter.RVViewHolder>() {
override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): RVViewHolder {
val layoutInflater = LayoutInflater.from(parent.context)
val view = RvItemBinding.inflate(layoutInflater, parent, false)
return RVViewHolder(view)
}
override fun onBindViewHolder(holder: RVViewHolder, position: Int) {
val realPosition = position % items.size
val item = items[realPosition]
holder.bind(item)
}
override fun getItemCount(): Int {
return items.size.toDouble().pow(10).toInt()
}
class RVViewHolder(private val binding: RvItemBinding) : RecyclerView.ViewHolder(binding.root) {
fun bind(item: String) {
val page = itemView.resources.getString(R.string.page)
binding.txtTitle.text = String.format(page, item)
}
}
}Usage:
private fun sampleWithRecyclerView() {
val recyclerView = findViewById<RecyclerView>(R.id.recycler_view)
val items = getFakeItems()
val adapter = RecyclerViewAdapter(items)
recyclerView.adapter = adapter
val snapHelper = PagerSnapHelper()
snapHelper.attachToRecyclerView(recyclerView)
val position = items.size.toDouble().pow(5).toInt()
recyclerView.scrollToPosition(position)
}
