Android 获取facebook封面照片

如何在我的应用程序中获取用户相册的封面照片？ 目前，我有这样一个json：

"id": "00000", 
  "albums": {
    "data": [
      {
        "id": "428076573767", 
        "from": {
          "name": "Benjamin", 
          "id": "00000"
        }, 
        "name": "Profile Pictures", 
        "link": "https://www.facebook.com/album.php?fbid=00000&id=00000&aid=00000", 
        "cover_photo": "10151465301937683", 
        "privacy": "everyone", 
        "count": 57, 
        "type": "profile", 
        "created_time": "2010-09-05T08:42:19+0000", 
        "updated_time": "2013-04-27T23:53:11+0000", 
        "can_upload": false
      }, 
}

如何通过URL获取封面照片？

您可以通过将此添加到URL来获取封面照片。无需从Json中提取封面照片

album['id']?>/picture?access_token=12345

  // where album is JSON array and access_token is random here..

试试这个。它会起作用的
