以下为内容演示：代码和结果图
首先先做好页面布局（用线性布局的方法）
以下为做好的页面布局.
在创建一个item布局文件来显示商品信息.
这样我们的页面布局就写完了.
listview要创建实体类，所以建立对应的实体类.
[java] view plain copy package com.example.bz0209.yukai.entity; /** * Created by Administrator on 2017/4/27. */ public class Goods { private long id; private String name; private Integer amount; public Goods(String name, long id, Integer amount) { this.name = name; this.id = id; this.amount = amount; } public Goods(String name, Integer amount) { this.name = name; this.amount = amount; } public long getId() { return id; } public void setId(long id) { this.id = id; } public Integer getAmount() { return amount; } public void setAmount(Integer amount) { this.amount = amount; } public String getName() { return name; } public void setName(String name) { this.name = name; } @Override public String toString() { return "Goods{" + "id=" + id + ", name='" + name + '\'' + ", amount=" + amount + '}'; } } <p>这样实体类就封装好了，接下来再创建适配器文件</p>创建一个GoodsAdpter类 <pre name="code" class="java">package com.example.bz0209.yukai; import android.content.Context; import android.support.annotation.NonNull; import android.view.LayoutInflater; import android.view.View; import android.view.ViewGroup; import android.widget.ArrayAdapter; import android.widget.ImageView; import android.widget.TextView; import java.util.List; /** * Created by Administrator on 2017/4/28. */ public class Goodsadpter extends ArrayAdapter<Goods > { private int resourceId; public Goodsadpter(Context context, int resource, List<Goods> objects) { super(context, resource, objects); resourceId=resource; } @NonNull @Override public View getView(int position, View convertView, ViewGroup parent) { Goods goods = getItem(position); View view=null; ViewHolder viewHolder; if(convertView==null){ view=LayoutInflater.from(getContext()).inflate(R.layout.item,null); viewHolder=new ViewHolder(); viewHolder.tvId= (TextView) view.findViewById(R.id.tvId); viewHolder.tvName= (TextView) view.findViewById(R.id.tvName); viewHolder.tvAmount= (TextView) view.findViewById(R.id.tvAmount); viewHolder.ivUp= (ImageView) view.findViewById(R.id.ivUp); viewHolder.ivDown= (ImageView) view.findViewById(R.id.ivDown); viewHolder.ivDelete= (ImageView) view.findViewById(R.id.ivDelete); view.setTag(viewHolder); }else{ view=convertView; viewHolder=(ViewHolder) view.getTag(); } viewHolder.tvId.setText(goods.getId()+""); viewHolder.tvName.setText(goods.getName()); viewHolder.tvAmount.setText(goods.getAmount()+""); return view; } class ViewHolder{ TextView tvId; TextView tvName; TextView tvAmount; ImageView ivUp; ImageView ivDown; ImageView ivDelete; } } </pre>这样我们就把与listview匹配的goodsadpter创建好了.<br> 接下来就是对数据库（还未完善）的操作，基本就可以完成了<br> <br> <pre></pre> <p></p> <p></p> <pre></pre> <pre></pre>
