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"); // 3119
                int cityCode = weatherutil.getCityCode(provinceCode, "大连"); // 974
                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;
    }

}
