вы можете увидеть это на видео. Я не могу найти способ перехватить события ввода касания, идущие к ItemTouchHelper

 class SwipeToDelete(var thoughtsAdapter: ThoughtsAdapter) : ItemTouchHelper.SimpleCallback(0,` 
ItemTouchHelper.LEFT) {
override fun onMove(
    recyclerView: RecyclerView,
    viewHolder: RecyclerView.ViewHolder,
    target: RecyclerView.ViewHolder
): Boolean {
    TODO("Not yet implemented")
}
   

 override fun onSwiped(viewHolder: RecyclerView.ViewHolder, direction: Int) {
        var adapterListPosition = viewHolder.adapterPosition
        thoughtsAdapter.deleteItem(adapterListPosition)
    }

}
class SwipeToSpread(var thoughtsAdapter: ThoughtsAdapter, val sharedViewModel: SharedViewModel) : 
ItemTouchHelper.SimpleCallback(0, ItemTouchHelper.RIGHT) {
    override fun onMove(recyclerView: RecyclerView, viewHolder: RecyclerView.ViewHolder, target: 
RecyclerView.ViewHolder): Boolean {
        TODO("Not yet implemented")
    }

override fun onSwiped(viewHolder: RecyclerView.ViewHolder, direction: Int) {
    var adapterListPosition = viewHolder.adapterPosition
    //TabButton.currentlyActive.value = sharedViewModel.spreadTabButton
    sharedViewModel.thoughtsTabButton.performClick()
}
}

фрагмент фрагмента, в котором это происходит:

     // FUNCTION values for the adapter
    val selectStrain = StrainsClickListener { strain -> thoughtsViewModel.selectStrain(strain)}
    val thoughtsAdapter = ThoughtsAdapter(thoughtsViewModel, thoughtsViewModel.selectedNote 
,clickSelectThought, clickSubStrainListener, imm, userDatabaseDao)
    val thoughtStrainAdapter = ThoughtStrainsAdapter(selectStrain, thoughtsViewModel.activeStrain, 
thoughtsViewModel, imm)

    // Function passed to the ItemTouchHelper to tell it what to do on swipe left
    val itemSwipeLeftThoughtHelper = ItemTouchHelper(SwipeToDelete(thoughtsAdapter))
    // attached the itemTouchHelper that is responsible for swipe left delete to the thoughtsAdapter
    itemSwipeLeftThoughtHelper.attachToRecyclerView(binding.thoughtsRecycler)

    // Swipe Right attached to the thoughtsRecycler to go to spread
    val itemSwipeRightThoughtHelper = ItemTouchHelper(SwipeToSpread(thoughtsAdapter, 
sharedViewModel))
    itemSwipeRightThoughtHelper.attachToRecyclerView(binding.thoughtsRecycler)

    binding.sharedViewModel = sharedViewModel
    binding.lifecycleOwner = viewLifecycleOwner
    binding.thoughtsViewModel = thoughtsViewModel
    binding.thoughtsRecycler.adapter = thoughtsAdapter
    binding.strainsBar.adapter = thoughtStrainAdapter
  

фрагмент внутреннего класса адаптера внешнего переработчика

    val layoutManager = LinearLayoutManager(thoughtHolder.itemView.context, 
LinearLayoutManager.HORIZONTAL, false )
        val subStrainRecycler = thoughtHolder.itemView.findViewById<RecyclerView> 
   (R.id.subStrainRecycler)
        val editButton = thoughtHolder.itemView.findViewById<ImageView>(R.id.brainButton)
        val thoughtContent = thoughtHolder.itemView.findViewById<EditText>(R.id.thought_content)
        editButton.setOnClickListener { thoughtsViewModel.changeScreenFromBtn()}

        val subStrainsAdapter = SubStrainsAdapter(thoughtsViewModel, clickSubStrain, imm, 
    thoughtItem.id, thoughtItem.strainName)
        subStrainRecycler.adapter = subStrainsAdapter
        subStrainRecycler.layoutManager = layoutManager
        subStrainsAdapter.addHeaderAndSubmitList(null)
  

пользовательский класс recycler, для которого я просто скопировал и вставил код в поисках решения:
https://pastebin.com/cywUWRZG

не работает, но также не причинил никакого вреда, как я вижу

Я действительно хочу, чтобы это сработало. я переделываю все это
