JSON，ListView AsyncHttpClient 等第三方包的综合实应用
来源：互联网 发布：蒙古族 知乎 编辑：程序博客网 时间：2024/05/20 02:24
前文中简单的介绍了 JSON 及其解析，现在将解析得到的数据应用到 ListView 上，所用的第三方包和 .aar 文件 如下图(.arr文件中有删减，留下精简部分，分享在我的云盘上：http://pan.baidu.com/s/1gdLtZXL，由于时间的推移，分享的版本可能跟不上以后的节奏，因为我不会去更新它们)：
总的运行效果如下：
大体思路如下：
（1）先从网络上读取 JSON 信息，文中有使用 AsyncTask 异步下载和第三方的开源包；
（2）解析 JSON 数据，并将其传递给 MyAdapter 类；
（3）在 MyAdapter 类中根据 getCardType() 信息分为 2 中在 ListView 中的显示方式：横，竖；
（4）为 ListView 添加头部 ListHeader (ListView 分为 3 部分: 头部 ListHeader, 内容部分(我们常用的部分) ContentView，底部 FooterView，其中：头部，底部一般不可见)；
（5）为了实现刷新的功能，利用的 google 提供的 SwipeRefreshLayout 刷新(注释掉的部分)，也可使用 XListView , XListView 源代码有精简；
代码信息见文中注解；
关于 .aar 文件在 AndroidStudio 中导入如下：
（1）先将其导入 libs 目录下，在如下图所示的目录结构中找到 build.gradle 文件；
（2）在如上图所示的序列号 1 (workspace 目录项目)中加入如下代码：
（3）在序列号 2 （workspace的子目录，如 app，或者 module项目）中加入如下代码：
JSON 的来源(Tomcat)如下图：
格式化后得到的 JSON 文件 around 如下：

（1）TotalT 类该类包含 resultCode，resultInfo，info 的信息：
package com.scxh.listlayout.parsejson;/** * Created by antimage on 2016/1/4. */public class TotalT { private String resultCode; private String resultInfo; private InfoT info; public String getResultCode() { return resultCode; } public void setResultCode(String resultCode) { this.resultCode = resultCode; } public String getResultInfo() { return resultInfo; } public void setResultInfo(String resultInfo) { this.resultInfo = resultInfo; } public InfoT getInfo() { return info; } public void setInfo(InfoT info) { this.info = info; }}（2）新建一个 InfoT 类包含 pageInfo，merchantKey：
package com.scxh.listlayout.parsejson;import java.util.List;/** * Created by antimage on 2016/1/4. */public class InfoT { private PageInfoT pageInfo; private List<MerchantKeyT> merchantKey; public List<MerchantKeyT> getMerchantKey() { return merchantKey; } public void setMerchantKey(List<MerchantKeyT> merchantKey) { this.merchantKey = merchantKey; } public PageInfoT getPageInfo() { return pageInfo; } public void setPageInfo(PageInfoT pageInfo) { this.pageInfo = pageInfo; }}（3）新建一个 PageInfoT 类包含 pageInfo 的信息：

package com.scxh.listlayout.parsejson;/** * Created by antimage on 2016/1/4. */public class MerchantKeyT { private String name; private String coupon; private String location; private String distance; private String picUrl; private String couponType; private String cardType; private String groupType; public String getName() { return name; } public void setName(String name) { this.name = name; } public String getCoupon() { return coupon; } public void setCoupon(String coupon) { this.coupon = coupon; } public String getLocation() { return location; } public void setLocation(String location) { this.location = location; } public String getDistance() { return distance; } public void setDistance(String distance) { this.distance = distance; } public String getPicUrl() { return picUrl; } public void setPicUrl(String picUrl) { this.picUrl = picUrl; } public String getCouponType() { return couponType; } public void setCouponType(String couponType) { this.couponType = couponType; } public String getCardType() { return cardType; } public void setCardType(String cardType) { this.cardType = cardType; } public String getGroupType() { return groupType; } public void setGroupType(String groupType) { this.groupType = groupType; }}MainActivity.java :
