Recyclerview设置TV布局(Kotlin)

Adapter

class Adapter(private val liveList: ArrayList<Information>): RecyclerView.Adapter<Adapter.ViewHolder>(){
  @SuppressLint("InflateParams")
  override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): Adapter.ViewHolder {
      val view = LayoutInflater.from(parent.context).inflate(R.layout.local_pictrues_cell,null)
      return ViewHolder(view)
  }
  override fun onBindViewHolder(holder: Adapter.ViewHolder, position: Int) {
      holder.itemView.imageview.setImageResource(liveList[position].image)
  }
  override fun getItemCount(): Int {
      return liveList.size
  }
  inner class ViewHolder(itemView: View):RecyclerView.ViewHolder(itemView){
  }
}

在界面中调用

@SuppressLint("WrongConstant")
  override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
      super.onViewCreated(view, savedInstanceState)
      addImageList()
      val adapter = Adapter(images)
      // 第一个参数为context  第二个参数为设置为两行，第三个参数为设置展示方向
      val layoutManager =
          GridLayoutManager(requireContext(), 2, GridLayoutManager.HORIZONTAL, false)
      // 设置layoutManager的元素占比
      layoutManager.spanSizeLookup = object : GridLayoutManager.SpanSizeLookup() {
          override fun getSpanSize(position: Int): Int {
              return when (position) {
                  // 0为第一个元素 2为独占两行
                  0 -> 2
                  else -> 1
              }
          }
      }
      recycler_view.adapter = adapter
      recycler_view.layoutManager = layoutManager
  }
