当我将ItemTouchHelper附加到主Recycler时，尝试使嵌套的recyclerView滚动

问题描述

您可以在视频中看到它。我找不到一种方法来拦截进入itemtouchhelper的输入触摸事件

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,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()
}
}

片段的片段，发生在以下位置：

    // 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

外部回收站的适配器类内部的片段

   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,thoughtItem.id,thoughtItem.strainName)
        subStrainRecycler.adapter = subStrainsAdapter
        subStrainRecycler.layoutManager = layoutManager
        subStrainsAdapter.addHeaderAndSubmitList(null)

自定义回收器类，我只是在搜索解决方案中复制并粘贴了代码： https://pastebin.com/cywUWRZG

不起作用，但也没有造成任何伤害

我真的希望这个工作。 id重做整个事情
