免费的天气Web Service接口

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）

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：

 public class MainActivity extends Activity {
 
     Button btn = null;
 
     TextView text = null;
 
     @Override
     protected void onCreate(Bundle savedInstanceState) {
         super.onCreate(savedInstanceState);
         setContentView(R.layout.activity_main);
 
         initView();
 
     }
 
     private void initView() {
         final WeatherUtil weatherutil = new WeatherUtil();
 
         btn = (Button) findViewById(R.id.btn);
         text = (TextView) findViewById(R.id.weatherInfo);
         btn.setOnClickListener(new Button.OnClickListener() {
 
             @Override
             public void onClick(View v) {
                 String weather = "";
                 int provinceCode = weatherutil.getProvinceCode("辽宁"); //
                 int cityCode = weatherutil.getCityCode(provinceCode, "大连"); //
                 List<String> weatherList = weatherutil.getWeather(cityCode);
                 for (String str : weatherList) {
 
                     weather = weather + str;
                 }
 
                 text.setText(weather);
 
             }
         });
     }
 
     @Override
     public boolean onCreateOptionsMenu(Menu menu) {
         getMenuInflater().inflate(R.menu.main, menu);
         return true;
     }
 
 }

获取天气的帮助类：
