带有NonScrollingGridLayoutManager的RecyclerView在拖放时变得迟钝

Question

我正在尝试使用NonScrollingGridLayoutManager在recyclerview中实现网格，并且为了进行回调，我正在使用ItemTouchHelperCallback，以便可以在网格内的任何位置拖放项目。它可以正常工作，但随后变得迟钝并导致UI卡住。任何线索都会有很大帮助！

    val recyclerView: RecyclerView = findViewById(R.id.revWords)
    recyclerView.setHasFixedSize(true)
    val layoutManager = NonScrollingGridLayoutManager(this)
    layoutManager.flexDirection = FlexDirection.ROW
    layoutManager.justifyContent = JustifyContent.CENTER
    recyclerView.layoutManager = layoutManager
    screenAdapter = ScreenAdapter(array) {
        touchHelper.startDrag(it)
    }
    val callback = ItemTouchHelperCallback(adapter)
    recyclerView.adapter = screenAdapter
    touchHelper = ItemTouchHelper(callback)
    touchHelper.attachToRecyclerView(recyclerView)
