获取天气的链接地址
根据经纬度获取：http://www.google.com/ig/api?weather=,,,31174165,121433841
【如中山的经纬度是：22.516997123628076,113.39263916015625 必须都乘以1000000才能作为参数】
int a=(int)22.516997123628076*1000000;
int b=(int)113.39263916015625*1000000;
String strUrl ="http://www.google.com/ig/api?hl=zh-cn&weather=,,,"+a+","+b;
System.out.println(strUrl);
根据地名获取：http://www.google.com/ig/api?hl=zh-cn&weather=Beijing
String strData = "";
String strUrl = "http://www.google.com/ig/api?hl=zh-cn&weather=ZhongShan";
strData = getResponse(strUrl);
// 天气预报的xml存储在sd卡中
new FileUnit().write(strData, "weather.xml");
// SAX解析xml
try {
SAXParserFactory spf = SAXParserFactory.newInstance();
SAXParser sp = spf.newSAXParser();
SAXReader saxReader = new SAXReader();
InputSource is = new InputSource();
is.setByteStream(new ByteArrayInputStream(strData.getBytes()));
sp.parse(is, saxReader);
weatherList=saxReader.getWeathList();
} catch (Exception e) {
e.printStackTrace();
}
//显示天气预报
showWeather();
根据地址 获得xml的String
protected String getResponse(String queryURL) {
URL url;
try {
url = new URL(queryURL.replace(" ", "%20"));
URLConnection urlconn = url.openConnection();
urlconn.connect();
InputStream is = urlconn.getInputStream();
BufferedInputStream bis = new BufferedInputStream(is);
ByteArrayBuffer buf = new ByteArrayBuffer(50);
int read_data = -1;
while ((read_data = bis.read()) != -1) {
buf.append(read_data);
}
// String resp = buf.toString();
String resp = EncodingUtils.getString(buf.toByteArray(), "GBK");
return resp;
} catch (MalformedURLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
return "";
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
return "";
}
}
