Inside fragment

@SuppressLint("ClickableViewAccessibility")
    override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
        super.onViewCreated(view, savedInstanceState)
        binding.rvSmallList.setOrientation(DSVOrientation.HORIZONTAL)
        binding.rvSmallList.setOffscreenItems(2)
        binding.rvSmallList.setOverScrollEnabled(false)
        binding.rvSmallList.setSlideOnFling(true)
        binding.rvSmallList.setSlideOnFlingThreshold(2100)
        binding.rvSmallList.setItemTransformer(ScaleTransformer.Builder()
                .setMaxScale(1f)
                .setMinScale(0.9f)
                .setPivotX(Pivot.X.CENTER) // CENTER is a default one
                .setPivotY(Pivot.Y.CENTER) // CENTER is a default one
                .build())
        binding.rvSmallList.adapter = VenueAdapter(vm.venueListSmall)
    }

adapter is pretty standard

class VenueAdapter(private val items: MutableList<VenueItem> = ArrayList()) RecyclerView.Adapter<VenueAdapter.ItemViewHolder>() {

   fun updateList(items: MutableList<VenueItem>) {
       this.items.clear()
       this.items.addAll(items)
       notifyDataSetChanged()
   }

   override fun getItemCount() = items.size

   override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): ItemViewHolder {
       return ItemViewHolder(VenueItemSmallBinding.inflate(LayoutInflater.from(parent.context), parent, false)
       )
   }

   override fun onBindViewHolder(holder: ItemViewHolder, position: Int) {
       holder.bind(getItem(position))
   }

   private fun getItem(position: Int) = items[position]

   inner class ItemViewHolder internal constructor(private val binding: VenueItemSmallBinding) :
           RecyclerView.ViewHolder(binding.root) {

       val vm = VenueItemViewModel()

       init {
           binding.vm = vm
           binding.executePendingBindings()
       }

       internal fun bind(item: VenueItem) {
        //   vm.venueItem.set(item)
         //  binding.executePendingBindings()
       }
   }
}

I am having the same issue. The onItemChangedListener works perfectly fine when you swipe on the screen but the view doesn't show. I also tried setting visibility in code but still, it doesn't show.

I have this problem in Fragment.
