android - 通过单击 Recyclerview 项调用 SlidingUpPanelLayout

Question

我是新手并实现了一个在单击项目时androidstudio调用的函数。喜欢这个gifslidinguppanellayoutrecyclerview

这是我尝试过的：

• binding使用or构建一个方法findviewbyid。但它失败了，因为我无法在recyerviewadapter.
• 用于intent切换activity。但我无法使用slidinguppanellayout.

同时，我找到了SlidingPaneLayout可能有助于解决问题的解决方案，但我无法弄清楚如何在slidinguppanellayout.

我找到的代码。来自安卓开发者

// A method on the Fragment that owns the SlidingPaneLayout,
// called by the adapter when an item is selected.

fun openDetails(itemId: Int) { 
   childFragmentManager.commit { 
      setReorderingAllowed(true)
      replace<ItemFragment>(R.id.detail_container, 
         bundleOf("itemId" to itemId)) 

// If we're already open and the detail pane is visible, 
// crossfade between the fragments. 

      if (binding.slidingPaneLayout.isOpen) { 
         setTransition(FragmentTransaction.TRANSIT_FRAGMENT_FADE) 
      } 
   } 
binding.slidingPaneLayout.open() 
}

我已经尝试了 2 周，但一直失败。你能告诉我当像上面的 gif 那样点击项目slidinguppanellayout时如何调用吗？recycerview

recyclerview adapter代码

class RecyclerViewAdapter(
        val itemList: ArrayList<CoinList>,
        val inflater: LayoutInflater
    ) : RecyclerView.Adapter<RecyclerViewAdapter.ViewHolder>(), Filterable {
        private var searchList: ArrayList<CoinList>? = null

        inner class ViewHolder(itemView: View) : RecyclerView.ViewHolder(itemView) {
            val name: TextView
            val count: TextView

            init {
                name = itemView.findViewById(R.id.coin_name)
                count = itemView.findViewById(R.id.coin_count)
            }
        }

        init {
            this.searchList = itemList
        }

        override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): ViewHolder {
            val view = inflater.inflate(R.layout.item_view, parent, false)
            return ViewHolder(view)
        }

        override fun onBindViewHolder(holder: ViewHolder, position: Int) {
            holder.name.setText(itemList.get(position).name)
            holder.count.setText(itemList.get(position).count)
            holder.itemView.setOnClickListener {
            }
        }

        override fun getItemCount(): Int {
            return itemList.size
        }
}

任何帮助，将不胜感激。谢谢 ：）
