页面上传一个从QQ邮箱导出的vcard文件，格式如下：
BEGIN:VCARDVERSION:3.0EMAIL;TYPE=HOME,INTERNET,pref:marketing@cache-FN:Cache Cache玩趣时尚N:;Cache Cache玩趣时尚;;;UID:7CBFDD99-8928-3646-86AE-1913A57F3B18END:VCARDBEGIN:VCARDVERSION:3.0EMAIL;TYPE=HOME,INTERNET,pref:hello@FN:Creative MarketN:;Creative Market;;;UID:ACD17D48-3036-9C4F-8A51-039897733752END:VCARD
在网上看了一些关于导出Android通讯录的例子，也是vcf格式的文件，但是格式不太一样，是类似这样的：
BEGIN:VCARDVERSION:2.1N;CHARSET=UTF-8;ENCODING=QUOTED-PRINTABLE:=E5=BC=A0=E4=B8=89;;FN;CHARSET=UTF-8;ENCODING=QUOTED-PRINTABLE:=E5=BC=A0=E4=B8=89TEL;VOICE;PREF:1-370-000-0000PHOTO;ENCODING=BASE64;PNG:iVBORw0KGgoAAAANSUhEUgAAAGAAAABgCAIAAABt+uBvAAAA。。。。END:VCARD
我在最上头放的那个链接就是解析这个格式vcf文件的。不过原理都是一样，使用正则表达式分组嘛~~感谢那位博主大大~~
我是需要这个文件里的email和name就可以了。就是FN和EMAIL这两个字段。

注意inputstream转为reader的时候的utf-8哦，不加可能会乱码。

导入成功：
