1.写一个一竖的自定义布局：

<?xml version="1.0" encoding="utf-8"?>

2.写一个适配器的类

package com.example.lenovo.myrecyclerview.RecyclerViewToolkit;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.example.lenovo.myrecyclerview.R;import java.util.List;/** * Created by lenovo on 2018/5/2. */public class ListAdapter extends RecyclerView.Adapter {    private List mDataList;    static class ViewHolder extends RecyclerView.ViewHolder{        ImageView imageAvatar;        TextView nameText;        TextView contentsText;        public ViewHolder(View itemView) {            super(itemView);            //注意这里可能需要import com.example.lenovo.myrecyclerview.R; 才能使用R.id            imageAvatar = (ImageView)itemView.findViewById(R.id.horizontalImageView);            nameText =(TextView) itemView.findViewById(R.id.horizontalTextViewName);            contentsText = (TextView)itemView.findViewById(R.id.horizontalTextViewContent);        }    }    public  ListAdapter(List listDatas){        mDataList = listDatas;    }    @Override    public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {        View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.layout_horizontal_list_view,                parent,false);        ViewHolder holder = new ViewHolder(view);        return holder;    }    @Override    public void onBindViewHolder(ViewHolder holder, int position) {        ListData listData = mDataList.get(position);        holder.imageAvatar.setImageResource(listData.getImageView());        holder.nameText.setText(listData.getNameText());        holder.contentsText.setText(listData.getContentsText());    }    @Override    public int getItemCount() {        return mDataList.size();    }}

3.在RecyclerView 横排列列表布局活动类中，将RecyclerView 排列方式修改成横向。

package com.example.lenovo.myrecyclerview;import android.support.v7.app.AppCompatActivity;import android.os.Bundle;import android.support.v7.widget.LinearLayoutManager;import android.support.v7.widget.RecyclerView;import com.example.lenovo.myrecyclerview.RecyclerViewToolkit.ListAdapter;import com.example.lenovo.myrecyclerview.RecyclerViewToolkit.ListData;import java.util.ArrayList;import java.util.List;public class RecyclerViewActivity extends AppCompatActivity {    private List listDatas = new ArrayList<>();    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_recycler_view);        addingData();        RecyclerView recyclerView = (RecyclerView)findViewById(R.id.RecyclerView);        //在此处修改布局排列方向        LinearLayoutManager layoutManager = new LinearLayoutManager(this);        layoutManager.setOrientation(LinearLayoutManager.HORIZONTAL);        recyclerView.setLayoutManager(layoutManager);        ListAdapter listAdapter = new ListAdapter(listDatas);        recyclerView.setAdapter(listAdapter);    }    public void addingData(){        ListData ace = new ListData(R.drawable.ace,"ace", "波特卡斯·D·艾斯：" +                "烧烧果实的前任能力者，绰号“火拳”，实力强大。");        listDatas.add(ace);        ListData arlong = new ListData(R.drawable.arlong,"arlong",                "恶龙海贼团：”由一群离开王下七武海之一甚平统治的鱼人所组成的海贼团，海贼船名为“鲨鱼˙斯帕布号”，" +                        "船头放置著和恶龙一样的锯齿状鼻子，由于总是到处上岸杀戮，成为恐怖和霸权的象征。");        listDatas.add(arlong);        ListData barbe_blanche = new ListData(R.drawable.barbe_blanche,"barbe_blanche",                "爱德华·纽盖特：外号“白胡子”。“四皇”之一（生前），白胡子海贼团的船长，实力极其强劲，被称为「世界最强男人」。" +                        "能力是被誉为最强超人系的震震果实，武器为薙刀。");        listDatas.add(barbe_blanche);//以下略。。。。。。。。。。    }}
