Question

ConnectionDetector cd = new ConnectionDetector(Healthcare.this);
isInternetPresent = cd.isConnectingToInternet();
if (isInternetPresent) {
 GPSTracker gps = new GPSTracker(this);
 Geocoder geoCoder = new Geocoder(Healthcare.this, Locale.getDefault());
 if (gps.canGetLocation()) {
     try {
             latitudecur = gps.getLatitude();
             longitudecur = gps.getLongitude();
             Log.d("latlong",""+latitudecur+longitudecur);
             List<Address> address = geoCoder.getFromLocation(latitudecur, longitudecur, 1);
                        Log.e("FInalAddress1",""+address.size());
                       ## Heading ##

                    } catch (NullPointerException e) {
                        // TODO: handle exception
                    } catch (NumberFormatException e) {
                        // TODO: handle exception
                    } catch (IOException e) {
                        e.printStackTrace();
                    }
                } else {

                }
            }

我写了上面的代码，但是在Log.e（“FInalAddress1”，“”+ address.size（））; address.getsize（）得到0.没有从这个代码获得，如地点，地址等上面代码的问题是什么？请帮忙感谢

如果它无效，您可以拨打谷歌提供的API

JSONObject jsonObject = getJsonResponse("http://maps.google.com/maps/api/geocode/json?latlng=" + mLatitude + "," + mLogitude + "&sensor=true");
    if (jsonObject != null) {
        try {
            JSONArray jsonArray = jsonObject.getJSONArray("results");
            for (int i = 0; i < jsonArray.length(); i++) {
                JSONObject addressResult = jsonArray.getJSONObject(i);
                String formattedAddress = addressResult.getString("formatted_address");
            }
        } catch (JSONException e) {
            e.printStackTrace();
        }
    }

错误：无法从Geocoder获取地址
