android解析json（以解析時时价为例），java也是一样的（二）
先把返回的json文档附上，以查询苹果为例：

看起来比较乱，确实是这样的，看这个我就废了半个小时，这只是其中一部分
返回的数据主要是这样的，这个里面包括两大部分，一个是pager，一个是products，这个pager是个jsonObject，而products是个jsonArray，如果你看了我的地一篇文章，或是对json有点了解，那么很容易的就可以看出来。
下面是正式的解析部分：
首先是链接网络的部分：
public String getJason(String url)throws Exception{
HttpClient client =new DefaultHttpClient();
HttpGet get=new HttpGet(url);
HttpResponse response=client.execute(get);
if(response.getStatusLine().getStatusCode()==200){
String result=EntityUtils.toString(response.getEntity());
return result;
}
return null;
}
这一部分是得到网络中你要解析的json的网络数据，返回的是字符串。
我所需要的只是products里面的数据，别的就不需要了，所以首先建立一个Bean类，product：
package com.test;
/**
* @author sjy
*
* @date 2012-8-17下午7:07:27
*/
public class Product {
private String id;
private String title;
private String url;
private String buyLink;
private String stock;
private String coversmall;
private String covermedium;
private String coverlarge;
private String lowPrice;
private String highPrice;
private String marketPrice;
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
public String getUrl() {
return url;
}
public void setUrl(String url) {
this.url = url;
}
public String getBuyLink() {
return buyLink;
}
public void setBuyLink(String buyLink) {
this.buyLink = buyLink;
}
public String getStock() {
return stock;
}
public void setStock(String stock) {
this.stock = stock;
}
public String getCoversmall() {
return coversmall;
}
public void setCoversmall(String coversmall) {
this.coversmall = coversmall;
}
public String getCovermedium() {
return covermedium;
}
public void setCovermedium(String covermedium) {
this.covermedium = covermedium;
}
public String getCoverlarge() {
return coverlarge;
}
public void setCoverlarge(String coverlarge) {
this.coverlarge = coverlarge;
}
public String getLowPrice() {
return lowPrice;
}
public void setLowPrice(String lowPrice) {
this.lowPrice = lowPrice;
}
public String getHighPrice() {
return highPrice;
}
public void setHighPrice(String highPrice) {
this.highPrice = highPrice;
}
public String getMarketPrice() {
return marketPrice;
}
public void setMarketPrice(String marketPrice) {
this.marketPrice = marketPrice;
}
public String toString(){
return id+url+buyLink+coversmall+covermedium+coverlarge+highPrice+lowPrice+marketPrice+stock+title;
}
}
这个便是需要解析获得的所有数据。
由于前面已经知道得到网络json的方法。那么下面便是正式解析json了：
首先要获得products这个数组：
String s=url；
String jsonString=“”；
try {
s=getJason(s);
JSONObject item=new JSONObject(s);
JSONArray array=item.getJSONArray("products");
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
这一步我们就可以获得products这个数组了。然后，我们对array里面的没一个object进行解析。
