无法实现反向地址解析 [英] Couldn't achieve Reverse Geocoding

问题描述

我的工作的GPS系统为Android。我能找到我的当前位置的经度和纬度，但是当我尝试我的经纬度转换成物理地址，我的code不起作用。我已经尝试了几种可能性。我已经张贴在这里我的code。

任何帮助很多AP preciated。
谢谢你。

  {尝试        清单＆LT;地址＆gt;地址= gc.getFromLocation（纬度，经度，1）;
        的System.out.println（+纬度）;
        StringBuilder的SB =新的StringBuilder（）;
        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）;
        。sb.append（address.getPostal code（））追加（\\ n）;
        sb.append（address.getCountryName（））;
        }
        addressString = sb.toString（）;
        }赶上（IOException异常五）{}
        }其他{
        latLongString =没有发现地点;
        }
        myLocationText.setText（您当前的位置为：\\ n+
        latLongString +\\ n+ addressString）;
        }
 

我的问题是，我不能让任何值列表与LT;地址＆gt;地址= gc.getFromLocation（纬度，经度，1）;
。它只返回一个空列表。
谁能告诉我是什么问题以及如何梳理出来......

解决方案

 地理codeR GC =新的地缘codeR（CTX，Locale.getDefault（））;
清单＆LT;地址＆gt;地址;
地址= gc.getFromLocation（纬度，经度，1）;
StringBuilder的SB =新的StringBuilder（）;
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））的附加（，）;
}
 

这会得到一个位置。但有时一个例外当属无法解析来自服务器的响应。您需要处理exception.Also检查清单中的 INTERNET权限。

I am working on GPS system for android. I am able to find the latitude and longitude of my current position, but when I try to convert my latitude and longitude into Physical address my code doesn't work. I have tried several possibilities. I have posted my code here.

Any help is much appreciated. Thanks.

try {

        List<Address> addresses = gc.getFromLocation(latitude, longitude, 1);
        System.out.println(""+latitude);
        StringBuilder sb = new StringBuilder();
        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");
        sb.append(address.getPostalCode()).append("\n");
        sb.append(address.getCountryName());
        }
        addressString = sb.toString();
        } catch (IOException e) {}
        } else {
        latLongString = "No location found";
        }
        myLocationText.setText("Your Current Position is:\n" +
        latLongString + "\n" + addressString);
        }

My problem is, I couldn't get any value in the List<Address> addresses = gc.getFromLocation(latitude, longitude, 1); . It returns a empty list only. Could anyone tell me what the problem is and how to sort it out...

解决方案

Geocoder gc = new Geocoder(ctx, Locale.getDefault());
List<Address> addresses;
addresses = gc.getFromLocation(lat, lng, 1);        
StringBuilder sb = new StringBuilder();
if (addresses.size() > 0) 
{
    Address address = addresses.get(0);
    for (int i = 0; i < address.getMaxAddressLineIndex(); i++)
         sb.append(address.getAddressLine(i)).append(",");
}

This would get a location. But sometimes an exception comes as "Unable to parse the response from server". You need to handle the exception.Also check for the INTERNET permission in the manifest.
