首先是activity_Main.xml

注意，少了下面那行活动页面会空白

app:layoutManager="androidx.recyclerview.widget.LinearLayoutManager"

1.然后需要创建一个java对象

public class NewsBean implements Serializable {
//    private String title;
    private String content;
    private int img;
//    private int


    public NewsBean(String content, int img) {
        this.content = content;
        this.img = img;
    }

    public String getContent() {
        return content;
    }

    public void setContent(String content) {
        this.content = content;
    }


    public int getImg() {
        return img;
    }

    public void setImg(int img) {
        this.img = img;
    }
}

2.创建一个MyAdater适配器

public class MyAdapter extends RecyclerView.Adapter<MyAdapter.MyHolder> {

    public List<NewsBean> mNewsBean=new ArrayList<>();

    public MyAdapter(List<NewsBean> mNewsBean) {
        this.mNewsBean = mNewsBean;
    }

    @NonNull
    @Override
    /*
    * 创建并返回一个ViewHolder
    * */
    public MyHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
        View view=LayoutInflater.from(parent.getContext()).inflate(R.layout.item,null);
        return new MyHolder(view);
    }


    /*
    * 数据绑定
    * */

    @Override
    public void onBindViewHolder(@NonNull MyHolder holder, int position) {
        NewsBean newsBean = mNewsBean.get(position);
        holder.tv.setText(newsBean.getContent());
        holder.imageView.setImageResource(newsBean.getImg());
//        holder.itemView.setId();

    }

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

    /*
    * 定义MyHolder并绑定控件；
    * */

    static class  MyHolder extends RecyclerView.ViewHolder{
        TextView tv;
        ImageView imageView;

        public MyHolder(@NonNull View itemView) {
            super(itemView);
            tv=itemView.findViewById(R.id.textView);
            imageView=itemView.findViewById(R.id.imageView);
        }
    }
}

4.MainActivity的代码

public class MainActivity extends AppCompatActivity {

    private RecyclerView recyclerView;
    private  MyAdapter myAdapter;
    private List<NewsBean> newsBeanList=new ArrayList<>();

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        recyclerView=findViewById(R.id.recyclerView);

        newsBeanList.add(new NewsBean("这是什么图片",R.drawable.thumb01));
        newsBeanList.add(new NewsBean("这是什么图片",R.drawable.thumb02));
        newsBeanList.add(new NewsBean("这是什么图片",R.drawable.thumb03));
        newsBeanList.add(new NewsBean("这是什么图片",R.drawable.thumb01));
//        newsBeanList.add(new NewsBean("zheshenme",R.drawable.thumb02));
        myAdapter=new MyAdapter(newsBeanList);
        recyclerView.setAdapter(myAdapter);
    }
}
