获取当前位置经纬度下的地名以及信息，首先获得通过GPS_PROVIDER活动当前的经纬度。然后访问数据库。通过Json方法进行HTTP协议访问获得网络数据。等到地名。

http语句如下：

//从经纬度获得地名

http://maps.googleapis.com/maps/api/geocode/json?latlng=40.714224,-73.961452&sensor=false

//从地名获得经纬度

http://maps.googleapis.com/maps/api/geocode/json?address=SFO&sensor=false

返回值 GeoCodeResponse的组成如下：

//address_component的组成如下：

private String getlocationName(Double Longitude,Double Latitude) {

String url="http://maps.googleapis.com/maps/api/geocode/json?latlng="+Latitude.toString()+","+Longitude.toString()+"&sensor=false";
System.out.println(url);
//建立访问
HttpClient httpClient=new DefaultHttpClient();

String responseData="";
String line="";

HttpParams httpParams = new BasicHttpParams();
HttpConnectionParams.setConnectionTimeout(httpParams,30000);
HttpConnectionParams.setSoTimeout(httpParams, 30000);
try {
HttpGet httpGet=new HttpGet(url);

HttpResponse response= httpClient.execute(httpGet);
HttpEntity entity=response.getEntity();
BufferedReader bufferReader=new BufferedReader(new InputStreamReader(entity.getContent()));

while((line = bufferReader.readLine() ) != null)
{
responseData+=line;
}

Gson gson =new Gson();

TestResult testResult = gson.fromjeson(responseData);

return testResult.locationName;

}
