写一个类继承Application

package com.wzq.moreitemlistviewdemo;

import android.app.Application;

import com.nostra13.universalimageloader.core.ImageLoader;
import com.nostra13.universalimageloader.core.ImageLoaderConfiguration;

public class MApp extends Application {//先注册.App@Overridepublic void onCreate() {    super.onCreate();    //开始构建    ImageLoaderConfiguration config = new ImageLoaderConfiguration.Builder(this).build();    //初始化imageloader;    ImageLoader.getInstance().init(config);    }}

封装好的Bean类

package com.wzq.moreitemlistviewdemo;

public class Goods {private String name;private String price;private int resId;private int typeId;public Goods(String name, String price, Integer typeId) {    super();    this.name = name;    this.price = price;    this.typeId = typeId;}public Goods(String name, String price, int resId, Integer typeId) {    super();    this.name = name;    this.price = price;    this.resId = resId;    this.typeId = typeId;}public int getTypeId() {    return typeId;}public void setTypeId(int typeId) {    this.typeId = typeId;}public String getName() {    return name;}public void setName(String name) {    this.name = name;}public String getPrice() {    return price;}public void setPrice(String price) {    this.price = price;}public int getResId() {    return resId;}public void setResId(int resId) {    this.resId = resId;}@Overridepublic String toString() {    return "Goods [name=" + name + ", price=" + price + ", resId=" + resId            + "]";    }}

主页面布局
