android 获取天气预报

开发环境android4.0.3

网上有很多android获取天气预报的方法，但是由于android版本更新，在主线程在禁止访问网络权限，因此需要创建一个新的线程连接WebService。

android的WebService 应用soap简单对象协议，这里采用ksoap2-android-assembly-2.5.4-jar-with-dependencies.jar开发包。

 

连接WebService主要接口如下：

  

public static SoapObject common(String methodName, HashMap<String, Object>map,String nameSpace, String endPoint){String soapAction = nameSpace + methodName; //指定WebService的命名空间和调用的方法名SoapObject rpc = new SoapObject(nameSpace,methodName ); //设置调用WebService就接口需要传入的参数if (null != map && map.size() > 0){Iterator<Entry<String, Object>> iter = map.entrySet().iterator();  while (iter.hasNext()) {  @SuppressWarnings("rawtypes")Map.Entry entry = (Map.Entry) iter.next();  Object key = entry.getKey();  Object val = entry.getValue();rpc.addProperty(key.toString(), val.toString());}} else{return null;}//生成调用WebService方法的SOAP请求信息，并制定soap的版本SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER10);envelope.bodyOut = rpc;//设置是否调用的doNet开发的WebServiceenvelope.dotNet = true;envelope.setOutputSoapObject(rpc);//设置连接超时时间为20秒HttpTransportSE transport = new HttpTransportSE(endPoint, timeout);try{ //调用WebServicetransport.call(soapAction, envelope);} catch (Exception e) {// TODO Auto-generated catch blocke.printStackTrace();//return "Error:调用web services出错！"+e.getMessage(); } //获取返回的数据SoapObject soapObject = null;try {soapObject = (SoapObject) envelope.getResponse();} catch (SoapFault e) {// TODO Auto-generated catch blocke.printStackTrace();return  null;}System.out.println("soap" + soapObject.toString());return soapObject;}

 

解析WebService返回的XML的天气预报内容

private String  parseWeather(SoapObject detail){String date = detail.getProperty(6).toString();if (date.isEmpty()){return "false";}String weatherToday = "今天：" + date.split(" ")[0];weatherToday = weatherToday + "\n天气：" + date.split(" ")[1];weatherToday = weatherToday + "\n气温："+ detail.getProperty(5).toString();weatherToday = weatherToday + "\n风力："+ detail.getProperty(7).toString() + "\n";System.out.println("weatherToday is " + weatherToday);  return weatherToday;}

 

获取天气预报的方法

public void  getWeather(String cityName){HashMap<String, Object> map = new HashMap<String, Object>();map.put("theCityName", cityName);SoapObject Result =  common( METHOD_NAME,map, NAMESPACE, URL);String ret = parseWeather(Result); Message msg = new Message();                                 msg.what = this.MESSAGE_WEATHER; Bundle bundle = new Bundle();     bundle.putString("weatherdata", ret); msg.setData(bundle);     mHandler.sendMessage(msg);}
