In a relatively unfamiliar environment, we often find some infrastructure in the surrounding area, such as banks, shopping malls, and restaurants (and more eager to find toilets ). Using the map API provided by Baidu, you can simply implement it in your application. For more information, see the place API. We take the search for the surrounding bank as an example. We need to determine at least three parameters. The longitude and latitude of the location to be searched, the type or Keyword of the content to be searched.
Public String getpalace (string query, string Lat, string LNG) throws clientprotocolexception, ioexception {
Httpclient = new defaulthttpclient ();
String url = palcerequesturl (query, Lat, LNG );
Logger. Log (level. info, URL );
Httpget = new httpget (URL );
Responsehandler <string> responsehandler = new basicresponsehandler ();
String responsebody = httpclient.exe cute (httpget, responsehandler); // location XML
Logger. Log (level. info, "Baidu response:" + responsebody );
Return responsebody;
}
Public String palcerequesturl (string query, string Lat, string LNG) throws unsupportedencodingexception {
String url = wechatconstant. baseurl + "place/search? Query = "+ urlencoder. encode (query," UTF-8 ") +" & Key ="
