免费的天气Web Service接口

在android应用当中很多时候需要获取天气的信息,这里提供怎么获取天气信息：

1. http://www.ayandy.com/Service.asmx?wsdl

 官网：http://www.ayandy.com

2. http://webservice.webxml.com.cn/WebServices/WeatherWS.asmx?wsdl

网站：http://www.webxml.com.cn/zh_cn/index.aspx ，此网站提供各种webservice接口

3.更多WS接口（天气预报，IP地址搜索，火车时刻表，汇率等等）

转至：http://developer.51cto.com/art/200908/147125.htm

在用网上的Web Service的接口的时候都要引入一个jar包：  下载地址

4.用android 的一个例子来获取天气数据：                         程序一定要注意是否打开了联网的权限

MainActivity：

 

 1 public class MainActivity extends Activity {
 2 
 3     Button btn = null;
 4 
 5     TextView text = null;
 6 
 7     @Override
 8     protected void onCreate(Bundle savedInstanceState) {
 9         super.onCreate(savedInstanceState);
10         setContentView(R.layout.activity_main);
11 
12         initView();
13 
14     }
15 
16     private void initView() {
17         final WeatherUtil weatherutil = new WeatherUtil();
18 
19         btn = (Button) findViewById(R.id.btn);
20         text = (TextView) findViewById(R.id.weatherInfo);
21         btn.setOnClickListener(new Button.OnClickListener() {
22 
23             @Override
24             public void onClick(View v) {
25                 String weather = "";
26                 int provinceCode = weatherutil.getProvinceCode("辽宁"); // 3119
27                 int cityCode = weatherutil.getCityCode(provinceCode, "大连"); // 974
28                 List<String> weatherList = weatherutil.getWeather(cityCode);
29                 for (String str : weatherList) {
30 
31                     weather = weather + str;
32                 }
33 
34                 text.setText(weather);
35 
36             }
37         });
38     }
39 
40     @Override
41     public boolean onCreateOptionsMenu(Menu menu) {
42         getMenuInflater().inflate(R.menu.main, menu);
43         return true;
44     }
45 
46 }
