推荐答案

您可以通过图形API获取来自Facebook的照片。从这里取 http://stackoverflow.com/a/5841825/1965084 ，看看下面code：

you can fetch photos from Facebook via the Graph API. Taken from here http://stackoverflow.com/a/5841825/1965084 , have a look at the following code:

ImageView user_picture;
userpicture=(ImageView)findViewById(R.id.userpicture);
URL img_value = null;
img_value = new URL("http://graph.facebook.com/"+id+"/picture?type=large");
Bitmap mIcon1 = BitmapFactory.decodeStream(img_value.openConnection().getInputStream());
userpicture.setImageBitmap(mIcon1);

我不知道，什么最好的方式来通知新上传的图片，但对于第一次从这里可以查看从时间元数据，以时间新条目：

I'm not sure, whats the best way to notify about new uploaded images, but for the first time you can check the meta data from time to time for new entries from here:

URL_TO_FACEBOOK + "me/albums" -> fetch albums
URL_TO_FACEBOOK + AlbumID + "/photos" -> to fetch photos of albums

这两种结果是JSON code，这样你就可以映射例如它与 GSON

UPDATE1：
首先看看Facebook的图形API 这里。尤其是这里您可以测试不同的方式通过图表来获取元数据。其基本原理是通过其用户ID（facebookname）和一个访问令牌（的此处描述）。然后你得到JSON输出作为回报，你可以映射到一个数组。要知道如何获取并映射JSON输出，你可以参考我刚才的问题这里。

Update1: First have a look at the Facebook Graph API here. Especially here you can test different ways to fetch meta data via graph. The basic principle is to fetch all albums from a user via its userid (facebookname) and an access token (described here). Then you get JSON output in return, that you can map to an array. To know how to fetch and map the json output, you might refer to my earlier question here.

您的问题指的是一个复杂的过程，大约需要通过URL Facebook的图形API，JSON映射和加载图像的知识。看看这个具体的例子，它可能为你工作，但你要明白json的映射，使用Apache HTTP的客户端和图形API。

Your question refers to a complex process that requires knowledge about the facebook graph api, json mapping and loading images via url. Have a look at this specific example, it might work for you but you need to understand json mapping, the use of apache http client and the graph api.
