如何解决当我将ItemTouchHelper附加到主Recycler时,尝试使嵌套的recyclerView滚动
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()
}
}
侧卷式回收机嵌套的外部回收机项目

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
