项目中用到根据距离排序,看百度地图帮助文档,试了几种方法都没有得以实现,最后通过网页版的json的以实现地址如下,传地址值即可
http://maps.google.com/maps/api/geocode/json?address=%E5%8C%97%E4%BA%AC%E9%82%AE%E7%94%B5%E5%A4%A7%E5%AD%A6&sensor=false
1 public JSONObject getLocationInfo(String address) { 2 // 发送json请求获取地址的json对象 3 HttpGet httpGet = new HttpGet("http://maps.google." 4 + "com/maps/api/geocode/json?address=" + address 5 + "ka&sensor=false"); 6 HttpClient client = new DefaultHttpClient(); 7 HttpResponse response; 8 StringBuilder stringBuilder = new StringBuilder(); 9 10 try { 11 response = client.execute(httpGet); 12 HttpEntity entity = response.getEntity(); 13 InputStream stream = entity.getContent(); 14 int b; 15 while ((b = stream.read()) != -1) { 16 stringBuilder.append((char) b); 17 } 18 } catch (ClientProtocolException e) { 19 } catch (IOException e) { 20 } 21 22 JSONObject jsonObject = new JSONObject(); 23 try { 24 jsonObject = new JSONObject(stringBuilder.toString()); 25 } catch (JSONException e) { 26 // TODO Auto-generated catch block 27 e.printStackTrace(); 28 } 29 return jsonObject; 30 } 31 32 public GeoPoint getGeoPoint(JSONObject jsonObject) { 33 // 解析json获取经纬度信息 34 Double lon = new Double(0); 35 Double lat = new Double(0); 36 37 try { 38 lon = ((JSONArray) jsonObject.get("results")).getJSONObject(0) 39 .getJSONObject("geometry").getJSONObject("location") 40 .getDouble("lng"); 41 42 lat = ((JSONArray) jsonObject.get("results")).getJSONObject(0) 43 .getJSONObject("geometry").getJSONObject("location") 44 .getDouble("lat"); 45 46 } catch (JSONException e) { 47 e.printStackTrace(); 48 } 49 return new GeoPoint((int) (lat * 1E6), (int) (lon * 1E6)); 50 }
