在Android开发中，一般的APP都是通过获取服务器端的数据来更新UI，从服务器获取到的数据可以是Json，它的数据量要比XML要小，这里解析中国天气网上获取的数据，虽然已经不再更新了，但用来学习还是可以的，为了方便我直接到数据通过txt保存到本地，它的数据可以通过这个页面获取：http://m.weather.com.cn/data/101280601.html
目录结构
其实解析也很简单，关键代码
private void json3() {
InputStream inputStream = null;
String weatherinfo = null;
try {
System.out.println("-------------------------------->json3");
inputStream = getResources().getAssets().open("weather.txt");
weatherinfo = convertStreamToString(inputStream);
} catch (IOException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
// 获取JSONObject对象
JSONObject jsonobject = null;
JSONObject jsoncity = null;
try {
jsonobject = new JSONObject(weatherinfo);
jsoncity = new JSONObject(jsonobject.getString("weatherinfo"));
WeatherInfo info = new WeatherInfo();
info.city = jsoncity.getString("city");
info.cityid = jsoncity.getString("cityid");
info.city_en = jsoncity.getString("city_en");
info.date = jsoncity.getString("date");

info.fx[1] = jsoncity.getString("fx2");
info.img[0] = jsoncity.getString("img1");
info.img[1] = jsoncity.getString("img2");
info.img[2] = jsoncity.getString("img3");
info.img[3] = jsoncity.getString("img4");

info.img_title[0] = jsoncity.getString("img_title1");
System.out.println("json = " + info.toString());
} catch (JSONException e) {
e.printStackTrace();
}
}我把天气信息单独封装出来
package com.example.jsondemo.domain;
import java.util.Arrays;
public class WeatherInfo {

public String cityid;
public String city_en;

public WeatherInfo() {

}
@Override

解析出来的结果
这些网站可以对Json数据进行格式化，看起来更方便
如果格式有错，会有提示，方便我们修改，有一点需要注意，创建文件保存Json数据时不能有换行
以下是错误的，这是为了我们方便理解
