RecyclerView的多条目及和点击

public class Showadapter extends RecyclerView.Adapter<RecyclerView.ViewHolder> {

    public static final int one = 0;
    public static final int tow = 1;
          //集合和上下文
    private List<ShowBean.ResultBean.MlssBean.CommodityListBeanXX> commodityList;
    private Context context;
          //有参
    public Showadapter(List<ShowBean.ResultBean.MlssBean.CommodityListBeanXX> commodityList, Context context) {
        this.commodityList = commodityList;
        this.context = context;
    }

    @NonNull
    @Override         //找布局   判断条目
    public RecyclerView.ViewHolder onCreateViewHolder(@NonNull ViewGroup viewGroup, int i) {
              View view;
            if (i==one){
                view=LayoutInflater.from(context).inflate(R.layout.z1,null,false);
                myviewholder myviewholder = new myviewholder(view);
                return myviewholder;
            }else
            {
            view=LayoutInflater.from(context).inflate(R.layout.zz1,null,false);
            myviewholder2 myviewholder2 = new myviewholder2(view);
            return myviewholder2;
        }

    }

    @Override      //多条目及点击事件
    public void onBindViewHolder(@NonNull RecyclerView.ViewHolder holder, final int i) {

           if (holder instanceof  myviewholder){
              ((myviewholder) holder).kt1.setText(commodityList.get(i).getCommodityName());
              ImageLoader.getInstance().displayImage(commodityList.get(i).getMasterPic(),((myviewholder) holder).kimge1);

              holder.itemView.setOnClickListener(new View.OnClickListener() {
                  @Override
                  public void onClick(View v) {
                      onclickLogin.getclike(i);
                  }
              });

          }else  if (holder instanceof  myviewholder2){
              ((myviewholder2) holder).kt2.setText(commodityList.get(i).getCommodityId()+"");
              holder.itemView.setOnClickListener(new View.OnClickListener() {
                  @Override
                  public void onClick(View v) {
                      onclickLogin.getclike(i);
                  }
              });
          }

    }

    @Override
    public int getItemViewType(int position) {
           if (position%2==0){
                return one;
           }
           return tow;
    }

    @Override
    public int getItemCount() {
        return commodityList.size();
    }

    public  class  myviewholder extends RecyclerView.ViewHolder{

        private final ImageView kimge1;
        private final TextView kt1;

        public myviewholder(@NonNull View itemView) {
              super(itemView);

            kimge1 = itemView.findViewById(R.id.image1);
            kt1 = itemView.findViewById(R.id.text1);

          }
      }

      public  class myviewholder2 extends RecyclerView.ViewHolder{

          private final TextView kt2;

          public myviewholder2(@NonNull View itemView) {
              super(itemView);

              kt2 = itemView.findViewById(R.id.text2);

          }
      }

    //接口回调
    public interface  OnclickLogin{
        void  getclike(int i);
        void  getlongclike(int i);
    }
    private OnclickLogin onclickLogin;
    public void  setOnclickLogin(OnclickLogin onclickLogin){
        this.onclickLogin=onclickLogin;
    }

}

获取点击activity 的方法 与接口回调相同 适配器的名字找set中的方法
直接在返回的方法中写需求

普通的RecyclerView使用方法

public class ShowAdapter extends RecyclerView.Adapter<ShowAdapter.viewholder> {
    Context context;
    List<Bean3.ResultBean> result;

    public ShowAdapter(Context context, List<Bean3.ResultBean> result) {
        this.context = context;
        this.result = result;
    }
    /////////////////////
    @NonNull
    @Override
    public viewholder onCreateViewHolder(@NonNull ViewGroup viewGroup, int i) {
          View view=LayoutInflater.from(context).inflate(R.layout.z1,null,false);
             viewholder viewholder = new viewholder(view);

              return viewholder;
    }
     /////////////////////
    @Override
    public void onBindViewHolder(@NonNull viewholder itemView, int i) {
       ImageLoader.getInstance().displayImage(result.get(i).getImageUrl(),itemView.kimage);

    }
    /////////////////////
    @Override

    }
    public class viewholder extends RecyclerView.ViewHolder{

        private final ImageView kimage;
        private final TextView kt1;

        public viewholder(@NonNull View itemView) {
            super(itemView);
            kimage = itemView.findViewById(R.id.image);
            kt1 = itemView.findViewById(R.id.text1);

        }
    }
