本文介绍了一个基于Android平台的自定义RecyclerView适配器实现过程，包括如何加载布局、设置监听及展示图片等内容。该适配器使用Glide库进行图片加载，并通过ViewHolder模式提高列表滚动效率。

package com.lbp.demo04;

import android.content.Context;
import android.support.v7.widget.RecyclerView;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ImageView;
import android.widget.TextView;
import com.bumptech.glide.Glide;

import java.util.List;

public class MyAdapter extends RecyclerView.Adapter<MyAdapter.MyViewHorder> {
    private Context context;
    private List<MyBean.MiaoshaBean.ListBeanX> list;
    private MyItemClick myitemclick;

    public MyAdapter(Context context,List<MyBean.MiaoshaBean.ListBeanX> list){
        this.context=context;
        this.list=list;
    }

    @Override
    public MyViewHorder onCreateViewHolder(ViewGroup parent, int viewType) {
        View view = LayoutInflater.from(context).inflate(R.layout.item, null);
        MyViewHorder viewHorder = new MyViewHorder(view);
        return viewHorder;
    }

    @Override
    public void onBindViewHolder(final MyViewHorder holder, final int position) {
        String s = list.get(position).getImages().substring(0, list.get(position).getImages().indexOf("|"));
        Glide.with(context).load(s).into(holder.imageView);
        holder.getTextView().setText(list.get(position).getSubhead());
    }

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

    public interface MyItemClick{
        void itemclick(View view,int position);
    }

    public void setOnMyItemClickListener(MyItemClick myitemclick){
        this.myitemclick=myitemclick;
    }

    class MyViewHorder extends RecyclerView.ViewHolder{
        private TextView textView;
        private ImageView imageView;

        public MyViewHorder(View itemView) {
            super(itemView);
            this.textView = itemView.findViewById(R.id.tv1);
            this.imageView = itemView.findViewById(R.id.img1);
        }

        public TextView getTextView(){
            return textView;
        }
        public void setTextView(TextView textView){
            this.textView=textView;
        }

        public ImageView getImageView(){
            return imageView;
        }
        public void setImageView(ImageView imageView){
            this.imageView=imageView;
        }


    }
