定位目前城市并擷取天氣資訊

一、描述步驟

1.定位api：http://pv.sohu.com/cityjson?ie=utf-8

例子：var returnCitySN = {"cip": "113.66.222.99", "cid": "440100", "cname": "廣東省廣州市"};

2.擷取天氣api：（中央氣象台接口）共3個步驟

步驟1：http://www.nmc.cn/rest/province （擷取全國省份的代碼）例如：廣東省：AGD

步驟2：http://www.nmc.cn/rest/province/AGD （擷取廣東省的所有城市代碼）例如：廣州市：59287

步驟3：http://www.nmc.cn/rest/weather?stationid=59287（北京七天的白天和夜晚的天氣資訊）

3.參考資料

中英天氣對照：https://wenku.baidu.com/view/2c211b48b52acfc788ebc92a.html

天氣預報圖例：http://www.weather.com.cn/static/html/legend.shtml

中央氣象台的API擷取天氣：（缺點沒有天氣圖示)

http://flash.weather.com.cn/wmaps/xml/china.xml

http://flash.weather.com.cn/wmaps/xml/beijing.xml

二、代碼

1.儲存天氣資訊類

public class WeatherForm {

//天氣描述

private String weather;

//圖示

private int img;

//省

private String provice;

//城市

private String city;

//省市

private String location;

public WeatherForm(){

}

public WeatherForm(String weather,int img, String provice,

String city, String location) {

super();

this.weather = weather;

this.img = img;

this.provice = provice;

this.city = city;

this.location = location;

}

public String getWeather() {

return weather;

}

public void setWeather(String weather) {

this.weather = weather;

}

public int getImg() {

return img;

}

public void setImg(int img) {

this.img = img;

}

public String getProvice() {

return provice;

}

public void setProvice(String provice) {

this.provice = provice;

}

public String getCity() {

return city;

}

public void setCity(String city) {

this.city = city;

}

public String getLocation() {

return location;

}

public void setLocation(String location) {

this.location = location;

}

@Override

public String toString() {

return "WeatherForm [weather=" + weather

+ ", img=" + img

+ ", provice=" + provice + ", city=" + city

+ ", location=" + location

+"]";

}

2.調用中央氣象台http接口，擷取天氣資訊jons包，解析分解需要的資訊

3.調用接口類擷取天氣

public void getweather()

{

Log.v(TAG," test getweather");

new Thread(new Runnable() {

@Override

public void run() {

Log.v(TAG," test getweather run");

//建立傳回的天氣資訊對象，是一個對象數組，用來放3天的天氣

WeatherForm[] WF = new WeatherForm[3];

//查詢天氣，傳回3天的天氣資訊

Log.v(TAG," test getweather::::");

WeatherQueryManage WQM = new WeatherQueryManage();

int count = 1;

while(!haveInternet())

{

Log.v(TAG," test count="+count);

if(count++>10) {

Log.v(TAG," test network disconnect!");

return;

}

try{

Thread.sleep(100);

}catch(Exception e){

Log.e(TAG," test sleep err! "+e);

}

Log.v(TAG," test haveInternet!");

WF = WQM.weatherquery();

if(null!=WF && WF.length>=1){

Log.v(TAG," test getweather: WF.length="+WF.length);

Log.v(TAG," test weather:"+WF[0].getWeather());

String weather = WF[0].getWeather();

Log.v(TAG," test weather send :"+weather);

Message message = new Message();

message.what = 99;

message.obj = WF[0].getWeather();

message.arg1 = WF[0].getImg();

Handler.sendMessage(message);

}

}).start();

}
