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
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）

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 }
获取天气的帮助类：
