Android programming method to obtain Sina weather forecast data

This paper illustrates the Android programming method to obtain sina weather forecast data. To share for your reference, the details are as follows:

Sina Weather Forecast Address:

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

Among them, the city available after city java. net. URLEncoder. encode (gb2312 "wuhan", ""); You can also write "Wuhan", but not "wuhan". Password fixed

Day is 0 for the weather of the day, 1 for the weather of the second day, 2 for the weather of the third day, and so on, the maximum is 4.

Tools:

1. Define members

/**  Sina Weather website  */
public final String SINA_URL = "http://php.weather.sina.com.cn/xml.php";
/**  Sina's weather XML Call the password  */
public final String PASSWORD = "DJOYnieT8234jlsK";
/**  city  */
public String city;
/**  The weather during the day  */
public String status1;
/**  At night the weather  */
public String status2;
/**  The weather during the day   pinyin  */
public String figure1;
/**  Night weather pinyin  */
public String figure2;
/**  The wind in the daytime  */
public String direction1;
/**  At night the wind  */
public String direction2;
/**  Takes place during the day  */
public String power1;
/**  The night wind scale  */
public String power2;
/**  Temperature during the day  */
public String temperature1;
/**  Night temperature  */
public String temperature2;
/**  Body feeling temperature  */
public String tgd;
/**  Uv index  */
public String zwx_l;
/**  Ultraviolet description  */
public String zwx_s;
/**  Somatosensory index  */
public String ssd_l;
/**  Somatosensory description  */
public String ssd_s;
/**  Air conditioning index  */
public String ktk_l;
/**  Air conditioning instructions  */
public String ktk_s;
/**  Washing index  */
public String xcz_l;
/**  Washing instructions  */
public String xcz_s;
/**  Dressing index  */
public String chy_l;
/**  Dress show  */
public String chy_shuoming;
/**  Pollutant diffusion condition  */
public String pollution_l;
/**  Description of pollutant diffusion conditions  */
public String pollution_s;
/**  A cold index  */
public String gm_l;
/**  A cold that  */
public String gm_s;
/**  Movement index  */
public String yd_l;
/**  Sports show  */
public String yd_s;

2. Get weather data

/**
*  Update the weather 
* 
* @param city
*    City name 
* @param day
*   0 Is the weather of the day, 1 According to the first 2 The weather of the day, 2 According to the first 3 The weather of the day, and so on, at most 4
*/
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. Access the network

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";
  }
}
