反向地理编码不工作 [英] reverse geocoding is not working

问题描述

我书面方式，需要查找当前位置的应用程序。在code将返回lattitude和经度正确，但犯规返回真实地址（反向地理编码）
可能是什么问题。
有人请帮帮忙，我是新来的Andr​​oid系统。
我与Android 4.0的模拟器上测试
updateWithNewLocation（）从onLocationChanged称为（位置LOC）方法

 无效updateWithNewLocation（地点）
          {
                    如果（位置！= NULL）
                    {
                            双纬度= 29.00; // location.getLatitude（）;
                            双LNG = 77.0; // location.getLongitude（）;
                            longitudeLattitudeString =Lattitude：+纬度+经度：+ LNG;
                            地理codeR GC =新的地缘codeR（这一点，Locale.getDefault（））;                            尝试
                            {
                                    清单＆LT;地址＆gt;地址= gc.getFromLocation（纬度，经度，1）;
                                    StringBuilder的SB =新的StringBuilder（）;
                                    //Toast.makeText(this，问题1，2000年）.show（）;
                                    如果（addresses.size（）大于0）
                                    {
                                            地址地址= addresses.get（0）;
                                            的for（int i = 0; I＆LT; address.getMaxAddressLineIndex（）;我++）
                                                。sb.append（address.getAddressLine（I））追加（\\ n）;
                                            。sb.append（address.getLocality（））追加（\\ n）;
                                            Toast.makeText（这一点，Problem2，2000年）.show（）;
                                            。sb.append（address.getPostal code（））追加（\\ n）;
                                            sb.append（address.getCountryName（））;
                                    }
                                    其他
                                    {
                                        addressString =没有位置;
                                        //Toast.makeText(this，Problem3，2000年）.show（）;
                                    }
                                    addressString = sb.toString（）;
                            }
                            赶上（IOException异常E）
                            {
                                //Toast.makeText(thisContext，问题：InCatch，2000年）.show（）;
                            }
                    }
                    其他
                    {
                            longitudeLattitudeString =没有发现地点;                    }
            }
 

解决方案

反向地理编码不与仿真，对器件测试工作。

I am writting an application which needs to find the current location. The code is returning lattitude and longitude correctly but doesnt return the real address(reverse geocoding) what could be problem. Someone please help, i am new to android. I am testing on emulator with android 4.0 updateWithNewLocation() is called from onLocationChanged(Location loc) method

         void updateWithNewLocation(Location location)
          {
                    if (location != null) 
                    {
                            double lat = 29.00;//location.getLatitude();
                            double lng = 77.0;//location.getLongitude();
                            longitudeLattitudeString="Lattitude :"+lat+" Longitude :"+lng;


                            Geocoder gc = new Geocoder(this, Locale.getDefault());

                            try 
                            {
                                    List<Address> addresses = gc.getFromLocation(lat, lng, 1);
                                    StringBuilder sb = new StringBuilder();
                                    //Toast.makeText(this, "Problem1", 2000).show();
                                    if (addresses.size() > 0)
                                    {
                                            Address address = addresses.get(0);
                                            for (int i = 0; i < address.getMaxAddressLineIndex(); i++)
                                                sb.append(address.getAddressLine(i)).append("\n");
                                            sb.append(address.getLocality()).append("\n");
                                            Toast.makeText(this, "Problem2", 2000).show();
                                            sb.append(address.getPostalCode()).append("\n");
                                            sb.append(address.getCountryName());
                                    }
                                    else
                                    {
                                        addressString="  No Location";
                                        //Toast.makeText(this, "Problem3", 2000).show();
                                    }
                                    addressString = sb.toString();
                            } 
                            catch (IOException e) 
                            {
                                //Toast.makeText(thisContext, "Problem : InCatch", 2000).show();
                            }
                    }


                    else 
                    {
                            longitudeLattitudeString = "No location found";    

                    }




            }

解决方案

Reverse Geocoding does not work with Emulator, test on device.
