利用Geocoder来进行为位置转换经纬度

 private String getAddress(String  adressStr) throws IOException {
        Geocoder geocoder = new Geocoder(this);
        boolean falg = geocoder.isPresent();
        KLog.e("the falg is " + falg);
        StringBuilder stringBuilder = new StringBuilder();
        try {

            //根据经纬度获取地理位置信息
//            List
 addresses = geocoder.getFromLocation(location.getLatitude(), location.getLongitude(), 1);

            //根据地址获取地理位置信息
            List
 addresses = geocoder.getFromLocationName(adressStr, 1);

            if (addresses.size() > 0) {
                Address address = addresses.get(0);
                for (int i = 0; i < address.getMaxAddressLineIndex(); i++) {
                    stringBuilder.append(address.getAddressLine(i)).append("\n");
                }
                stringBuilder.append(address.getCountryName()).append("_");//国家
                stringBuilder.append(address.getFeatureName()).append("_");//周边地址
                stringBuilder.append(address.getLocality()).append("_");//市
                stringBuilder.append(address.getPostalCode()).append("_");
                stringBuilder.append(address.getCountryCode()).append("_");//国家编码
                stringBuilder.append(address.getAdminArea()).append("_");//省份
                stringBuilder.append(address.getSubAdminArea()).append("_");
                stringBuilder.append(address.getThoroughfare()).append("_");//道路
                stringBuilder.append(address.getSubLocality()).append("_");//香洲区
                stringBuilder.append(address.getLatitude()).append("_");//经度
                stringBuilder.append(address.getLongitude());//维度
                KLog.e(stringBuilder.toString());
            }
        } catch (IOException e) {
            // TODO Auto-generated catch block
            Toast.makeText(this, "报错", Toast.LENGTH_LONG).show();
            e.printStackTrace();
        }
        return stringBuilder.toString();

    }
