1， 1个书籍类

package com.example.t211_06;

public class Book {
	private Integer id;
	private String title;
	private String author;

	private Float price;
	private String publish;
	private String remark;

	private int image;

	public Book() {
		super();
	}

	public int getImage() {
		return image;
	}

	public void setImage(int image) {
		this.image = image;
	}

	public Integer getId() {
		return id;
	}

	public void setId(Integer id) {
		this.id = id;
	}

	public String getTitle() {
		return title;
	}

	public void setTitle(String title) {
		this.title = title;
	}

	public String getAuthor() {
		return author;
	}

	public void setAuthor(String author) {
		this.author = author;
	}

	public Float getPrice() {
		return price;
	}

	public void setPrice(Float price) {
		this.price = price;
	}

	public String getPublish() {
		return publish;
	}

	public void setPublish(String publish) {
		this.publish = publish;
	}

	public String getRemark() {
		return remark;
	}

	public void setRemark(String remark) {
		this.remark = remark;
	}

}

2，书籍插入数据类

package com.example.t211_06;

import java.util.ArrayList;
import java.util.List;

public class BookDao {

	private int[] bookImages = new int[] { R.drawable.book1, R.drawable.book2,
			R.drawable.book3, R.drawable.book4, R.drawable.book5,
			R.drawable.book6, R.drawable.book7, R.drawable.book8,
			R.drawable.book9, R.drawable.book10 };

	public List<Book> list() {
		List<Book> list = new ArrayList<Book>();
		for (int i = 1; i <= 1000; i++) {
			Book b = new Book();
			b.setId(i);
			b.setTitle("t" + i);
			b.setAuthor("a" + i);
			b.setPrice(0.0f + i);
			b.setPublish("p" + i);
			b.setRemark("r" + i);
	// 真实开发图片应该是从网络获取，而非本地获得
			b.setImage(bookImages[i % bookImages.length]);

			list.add(b);
		}

		return list;
	}
}

3，1个资源xml

5，开始敲代码

package com.example.t211_06;

import android.content.Context;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.ImageView;
import android.widget.ListView;
import android.widget.TextView;

import java.util.List;

public class MainActivity extends AppCompatActivity {

    private List<Book> data;
    private ListView lv_main_booklist;
    private MyBaseAdapter Adapter;

    //自定义适配器
    public class MyBaseAdapter extends BaseAdapter{

        public class viewHolder{//内部类
            ImageView iv_listviewitem_image;
            TextView tv_listviewitme_title;
            TextView tv_listviewitme_author;
            TextView tv_listviewitme_price;
            TextView tv_listviewitme_publish;
            TextView tv_listviewitme_remark;

        }
         private LayoutInflater inflater;//解析试图

        //构造器
        public MyBaseAdapter(LayoutInflater inflater) {
            this.inflater = inflater;
        }

        @Override
        public int getCount() {
            return data.size();
        }

        @Override
        public Object getItem(int position) {
            return data.get(position);
        }

        @Override
        public long getItemId(int position) {
            return position;
        }

        @Override
        public View getView(int position, View convertView, ViewGroup parent) {

            View v = convertView;
            if(v==null){
                Log.i("text",""+position);
                v=inflater.inflate(R.layout.listview_item, null);
                viewHolder vn=new viewHolder();
                vn.iv_listviewitem_image=v.findViewById(R.id.iv_listviewitem_image);
                vn.tv_listviewitme_title=v.findViewById(R.id.tv_listviewitme_title);
                vn.tv_listviewitme_author=v.findViewById(R.id.tv_listviewitme_author);
                vn.tv_listviewitme_price=v.findViewById(R.id.tv_listviewitme_price);
                vn.tv_listviewitme_publish=v.findViewById(R.id.tv_listviewitme_publish);
                vn.tv_listviewitme_remark=v.findViewById(R.id.tv_listviewitme_remark);
                 v.setTag(vn);  //保存数据控件
            }

            //获取数据控件
            viewHolder tag = (viewHolder) v.getTag();
            //获取当前的数据，封装进实体类里面去
            Book book = data.get(position);
            tag.iv_listviewitem_image.setImageResource(book.getImage());
            tag.tv_listviewitme_title.setText(book.getTitle());
            tag.tv_listviewitme_author.setText(book.getAuthor());
            tag.tv_listviewitme_price.setText(book.getPrice()+"");
            tag.tv_listviewitme_publish.setText(book.getPublish());
            tag.tv_listviewitme_remark.setText(book.getRemark());

            return v;
        }
    }
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        lv_main_booklist=findViewById(R.id.lv_main_booklist);

        //获取数据
        data=new BookDao().list();
        Adapter=new MyBaseAdapter((LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE));
        lv_main_booklist.setAdapter(Adapter);

    }
}
