我已经创建了一个通用适配器，该适配器将用于RecyclerView中的任何类型的数据和任意数量的项目（行布局）。

  

我已将clicklistener添加到它的GeneralViewHolder中。此适配器是否存在任何缺陷或问题。有没有减少recyclerView的回调？

GenericAdapter.kt

class GenericAdapter<T>(protected val items: List<T>,val adapterBind: OnAdapterBind<T>)
    : RecyclerView.Adapter<GeneralViewHolder<T>>() {

    override fun onCreateViewHolder(parent: ViewGroup,viewType: Int): GeneralViewHolder<T> =
            GeneralViewHolder(parent,viewType) { position,mView ->
                adapterBind.onItemClicked(position,mView)
            }

    override fun getItemCount(): Int = items.size
    override fun getItemViewType(position: Int): Int = adapterBind.setLayoutId(position,items[position]);

    override fun onBindViewHolder(holder: GeneralViewHolder<T>,position: Int) {
        adapterBind.onBindData(holder.itemView,items[position])
    }
}

GeneralViewHolder.kt

class GeneralViewHolder<T>(parent: ViewGroup,layoutId: Int,clicklistener : (pos: Int,aView: View) -> Unit) : RecyclerView.ViewHolder(
        LayoutInflater.from(parent.context).inflate(layoutId,parent,false)){

    init {
        itemView.setOnClicklistener{
            clicklistener.invoke(adapterPosition,itemView)
        }
    }
}

OnAdapterBind.class

public interface OnAdapterBind<T> {
    ///GeneralViewHolder setViewHolder(ViewGroup parent,int viewType);
    void onBindData(View itemView,T data);
    int setLayoutId(int position,T obj);
    void onItemClicked(int position,View mView);
}

对于单个项目类型，请像这样

val carList = listOf<Car>(Car("Moras",Color.BLACK),Car("honda",Color.BLUE),Car("audi",Car("Moras",Color.BLACK))
            recyclerView.adapter = GenericAdapter<Car>( carList,object : OnAdapterBind<Car> {

                override fun onBindData(itemView: View?,data: Car?) {
                    itemView?.fruitTv?.text = data?.name
                }

                override fun setLayoutId(position: Int,obj: Car?): Int = R.layout.item_fruit

                override fun onItemClicked(position: Int,mView: View?) {
                    Toast.makeText(this@Fruitactivity,"Clicked -> " + position,Toast.LENGTH_LONG).show()
                }
            })

并供ViewType的MultipleType使用。.

val list= listOf<Any>(Car("audi",Bus("Eicher",Bus("Benz",Car("Suzuki",Color.WHITE),Color.BLACK))




recyclerView.adapter = GenericAdapter<Any>( list,object : OnAdapterBind<Any> {

            override fun onBindData(itemView: View?,data: Any?) {
                when(data){
                    is Car -> itemView?.fruitTv?.text = "Car Rasha"
                    is Bus -> itemView?.vegetableTv?.text = "Bus Bus"
                }
            }

            override fun setLayoutId(position: Int,obj: Any?): Int {
                when(obj){
                    is Car -> R.layout.item_fruit
                    is Bus -> R.layout.item_vegetable
                }
                return R.layout.item_fruit
            }

            override fun onItemClicked(position: Int,mView: View?) {

            }
        })
