该程序在上一个程序的基础上 改进 添加了获取天气状态

该程序调用中央气象局API 有多种数据：

http://www.weather.com.cn/data/sk/101010100.html 简单的实时天气json 数据
http://m.weather.com.cn/data/101270101.html 包含详细的天气预报信息

后者 如下例子：

{"weatherinfo":{

前者例子：

{"weatherinfo"{"city":"北京",
"cityid":"101010100",//城市编号
"temp":"14",//实时气温
"WD":"东风",//风向
"WS":"级", //单位
"SD":"71%",//湿度
"WSE":"2", //风级
"time":"13:00",
"isRadar":"1",
"Radar":"JC_RADAR_AZ9010_JB"
}
}

只是数据不同 实现完全相同 简单起见 使用后者进行解析

1配置文件 在前篇博客的基础上加入互联网权限

2 WeatherInfo.java WeatherModel.java

package com.cityselection;

public class WeatherModel {

private WeatherInfo weatherinfo =new WeatherInfo();

public WeatherInfo getWeatherinfo() {
return weatherinfo;
}

public void setWeatherinfo(WeatherInfo weatherinfo) {
this.weatherinfo = weatherinfo;
}

}

package com.cityselection;

public class WeatherInfo {
private String city;//城市名称
private String temp;//实时气温
private String WD;//风向
private String WS;//风级
public String getCity() {
return city;
}
public void setCity(String city) {
this.city = city;
}
public String getTemp() {
return temp;
}
public void setTemp(String temp) {
this.temp = temp;
}
public String getWD() {
return WD;
}
public void setWD(String wD) {
WD = wD;
}
public String getWS() {
return WS;
}
public void setWS(String wS) {
WS = wS;
}

}

3.布局文件main.xml
