Android编程实现获取新浪天气预报数据的方法

本文实例讲述了Android编程实现获取新浪天气预报数据的方法。分享给大家供大家参考，具体如下：

新浪天气预报地址：

http://php.weather.sina.com.cn/xml.php?city=武汉&password=DJOYnieT8234jlsK&day=0

其中，city后的城市可用java.net.URLEncoder.encode(“武汉”,” gb2312”);也可以直接写”武汉”，但不能用”wuhan”。Password固定

Day为0表示当天天气，1表示第二天的天气，2表示第三天的天气，以此类推，最大为4。

工具类：

1、定义成员

public final String SINA_URL = "http://php.weather.sina.com.cn/xml.php";

public final String PASSWORD = "DJOYnieT8234jlsK";

public String city;

public String status1;

public String status2;

public String figure1;

public String figure2;

public String direction1;

public String direction2;

public String power1;

public String power2;

public String temperature1;

public String temperature2;

public String tgd;

public String zwx_l;

public String zwx_s;

public String ssd_l;

public String ssd_s;

public String ktk_l;

public String ktk_s;

public String xcz_l;

public String xcz_s;

public String chy_l;

public String chy_shuoming;

public String pollution_l;

public String pollution_s;

public String gm_l;

public String gm_s;

public String yd_l;

public String yd_s;

2、获取天气数据

public void UpdateWeatherInfo(String city, String day) {
  if (city.equals("")) {
   isLoaded = false;
   return;
  }
  String html = null;
  try {
   html = doGet(SINA_URL + "?city="
     + java.net.URLEncoder.encode(city, "gb2312") + "&password="
     + PASSWORD + "&day=" + day);
   document doc = Jsoup.parse(html);
   if (doc.body().getElementsByTag("Profiles").size() == 0) {
    isLoaded = false;
    return;
   }
   if (doc.body().getElementsByTag("Profiles").get(0).getElementsByTag("Weather").size() == 0) {
    isLoaded = false;
    return;
   }
   Element element = doc.body().getElementsByTag("Profiles").get(0)
     .getElementsByTag("Weather").get(0);
   this.city = element.getElementsByTag("city").text();
   status1 = element.getElementsByTag("status1").text();
   status2 = element.getElementsByTag("status2").text();
   figure1 = element.getElementsByTag("figure1").text();
   figure2 = element.getElementsByTag("figure2").text();
   direction1 = element.getElementsByTag("direction1").text();
   direction2 = element.getElementsByTag("direction2").text();
   power1 = element.getElementsByTag("power1").text();
   power2 = element.getElementsByTag("power2").text();
   temperature1 = element.getElementsByTag("temperature1").text();
   temperature2 = element.getElementsByTag("temperature2").text();
   tgd = element.getElementsByTag("tgd").text();
   zwx_l = element.getElementsByTag("zwx_l").text();
   zwx_s = element.getElementsByTag("zwx_s").text();
   ssd_l = element.getElementsByTag("ssd_l").text();
   ssd_s = element.getElementsByTag("ssd_s").text();
   ktk_l = element.getElementsByTag("ktk_l").text();
   ktk_s = element.getElementsByTag("ktk_s").text();
   xcz_l = element.getElementsByTag("xcz_l").text();
   xcz_s = element.getElementsByTag("xcz_s").text();
   chy_l = element.getElementsByTag("chy_l").text();
   chy_shuoming = element.getElementsByTag("chy_shuoming").text();
   pollution_l = element.getElementsByTag("pollution_l").text();
   pollution_s = element.getElementsByTag("pollution_s").text();
   gm_l = element.getElementsByTag("gm_l").text();
   gm_s = element.getElementsByTag("gm_s").text();
   yd_l = element.getElementsByTag("yd_l").text();
   yd_s = element.getElementsByTag("yd_s").text();
   isLoaded = true;
  } catch (UnsupportedEncodingException e) {
   isLoaded = false;
  }
}

3、访问网络

public static final String ENCODE = "utf-8";
public static String doGet(String url) {
  try {
   HttpGet httpGet = new HttpGet(url);
   HttpClient hc = new DefaultHttpClient();
   HttpResponse ht = hc.execute(httpGet);
   if (ht.getStatusLine().getStatusCode() == HttpStatus.SC_OK) {
    HttpEntity he = ht.getEntity();
    InputStream is = he.getContent();
    BufferedReader br = new BufferedReader(
      new InputStreamReader(is));
    String response = "";
    String readLine = null;
    while ((readLine = br.readLine()) != null) {
     response = response + readLine;
    }
    is.close();
    br.close();
    return response;
   } else {
    return "error";
   }
  } catch (Exception e) {
   return "error";
  }
}
