访问中国天气网获取最近三天的数据

首先上一个效果图

这是本人在一款app中所用到的数据，获取最近三天中国天气网上的数据。

怎么说呢中国天气网上的数据比较乱，但是相比其他网站上的数据，中国天气网上的数据还是比较稳定的。

http://ws.webxml.com.cn/WebServices/WeatherWS.asmx 这个就是接口地址，上面不仅有天气的数据还有国家和城市的数据

可以采用webservice方式调用接口，也可以用java代码调用接口，我是采用java代码调用天气接口的

http://ws.webxml.com.cn/WebServices/WeatherWS.asmx?op=getWeather 天气预报接口地址

我是采用post方式调的接口

大家注意一下中国天气网上传过来的数据是一个一维数据，所以处理这个字符串就比较麻烦

这是我访问地址以及处理数据的代码

private void getWeather(String theCityName) {
       UIHelper.showDialogForLoading(getActivity(), "加载数据请稍后...", true);
       wts.clear();
       FormBody.Builder builder = new FormBody.Builder();
       builder.add("theCityName", theCityName);

       RequestBody formBody = builder.build();
       final Request request = new Request.Builder().url(Contant.weatherurl)
               .post(formBody).build();
       client.newCall(request).enqueue(callback2);
   }

   // 请求后的回调方法
   private Callback callback2 = new Callback() {
       @Override
       public void onFailure(Call call, IOException e) {
           setResult2(e.getMessage(), false);
       }

       @Override
       public void onResponse(Call call, Response response) throws IOException {
           setResult2(response.body().string(), true);
       }
   };

   // 显示请求返回的结果
   private void setResult2(final String msg, final boolean success) {
       getActivity().runOnUiThread(new Runnable() {
           @Override
           public void run() {
               if (success) {
                   UIHelper.hideDialogForLoading();
                   System.out.println("msg::" + msg);
                   // InputStream input =new new
                   // ByteArrayInputStream(str.getBytes("UTF-8"))
                   try {
                       weather = (ArrayList<String>) XmlPull
                               .getWeather(new ByteArrayInputStream(msg
                                       .getBytes("UTF-8")));
                       // for(int i=0;i<weather.size();i++){
                       // System.out.println("i="+weather.get(i));
                       String weather1 = weather.get(6);
                       String weather2 = weather.get(5);

                       System.out.println("weather4="+weather4);
                       String[] weather11 = weather1.split(" ");
                       String[] weather44 = weather4.split("\\.");
                       //System.out.println("weather11="+weather11[0]+",weather11="+weather11[1]);

               }

           }


       });
   }

还有一点大家要是想让自己app显示自定义图片，下载中国天气网上的图片包，将自己的图片名称改为对应天气图标即可
