android - 如何从经纬度获取村名、区和街道

Question

我有经纬度坐标，我想从中获取村庄名称区和子区。我搜索并找到了没有给出村庄名称的反向地理编码。是否有任何 api 或代码库可从经纬度获取准确位置。我想在我的 Android 应用程序中展示这一点。

Geocoder geocoder = new Geocoder(this, Locale.getDefault());
        String result = null;
        try {
            List<Address> addressList = geocoder.getFromLocation(
                    25.882456,83.174279, 1);
            if (addressList != null && addressList.size() > 0) {
                Address address = addressList.get(0);
                StringBuilder sb = new StringBuilder();
                for (int i = 0; i < address.getMaxAddressLineIndex(); i++) {
                    sb.append(address.getAddressLine(i)).append("\n");//adress
                }
                sb.append(address.getLocality()).append("\n");//village

                sb.append(address.getPostalCode()).append("\n");
                sb.append(address.getCountryName());
                sb.append(address.getAdminArea()).append("\n"); //state

                sb.append(address.getSubAdminArea()).append("\n");//district


                result = sb.toString();
            }
        } catch (IOException e) {
           // Log.e(TAG, "Unable connect to Geocoder", e);
        }

我修改了你的代码，它正在工作
