使用json获取当前位置

要改回可读格式，您也可以使用Geoprer，但有时由于Google Play服务问题而无法正常工作。我将这个json地理编码用作第二种选择，以防万一。

请参考 Google Geocoding
API

工作流程是通过您的纬度和经度并获取当前位置。请求网址将是这样。

String reqURL = "http://maps.googleapis.com/maps/api/geopre/json?latlng="+ lat+","+lng +"&sensor=true";

希望这个答案对您有帮助。

public static JSonObject getLocationInfo(double lat, double lng) {    HttpGet httpGet = new HttpGet("http://maps.googleapis.com/maps/api/geopre/json?latlng="+ lat+","+lng +"&sensor=true");    HttpClient client = new DefaultHttpClient();    HttpResponse response;    StringBuilder stringBuilder = new StringBuilder();    try {        response = client.execute(httpGet);        HttpEntity entity = response.getEntity();        InputStream stream = entity.getContent();        int b;        while ((b = stream.read()) != -1) { stringBuilder.append((char) b);        }    } catch (ClientProtocolException e) {    } catch (IOException e) {    }    JSonObject jsonObject = new JSonObject();    try {        jsonObject = new JSonObject(stringBuilder.toString());    } catch (JSonException e) {        e.printStackTrace();    }    return jsonObject;}public static String getCurrentLocationViaJSON(double lat, double lng) {    JSonObject jsonObj = getLocationInfo(lat, lng);    Log.i("JSON string =>", jsonObj.toString());    String currentLocation = "testing";    String street_address = null;    String postal_pre = null;    try {        String status = jsonObj.getString("status").toString();        Log.i("status", status);        if(status.equalsIgnoreCase("OK")){ JSonArray results = jsonObj.getJSonArray("results"); int i = 0; Log.i("i", i+ "," + results.length() ); //TODO delete this do{     JSonObject r = results.getJSonObject(i);     JSonArray typesArray = r.getJSonArray("types");     String types = typesArray.getString(0);     if(types.equalsIgnoreCase("street_address")){         street_address = r.getString("formatted_address").split(",")[0];         Log.i("street_address", street_address);     }else if(types.equalsIgnoreCase("postal_pre")){         postal_pre = r.getString("formatted_address");         Log.i("postal_pre", postal_pre);     }     if(street_address!=null && postal_pre!=null){         currentLocation = street_address + "," + postal_pre;         Log.i("Current Location =>", currentLocation); //Delete this         i = results.length();     }     i++; }while(i<results.length()); Log.i("JSON Geo Locatoin =>", currentLocation); return currentLocation;        }    } catch (JSonException e) {        Log.e("testing","Failed to load JSON");        e.printStackTrace();    }    return null;}

根据我的经验， 只有设备生成的纬度和经度 会起作用。然后打电话

String currentLocation = getCurrentLocationViaJSON(lat, lng);
