profPict=BitmapFactory.decodeStream(image_value.openConnection().getInputStream());

不过，我没有得到期望的结果。

But I don't get the desired result.

推荐答案

您应该改变你的code以下内容：

You should change your code following:

URL image_value = new URL("http://graph.facebook.com/"+id+"/picture" );

可能GET参数的URL可以在这里找到： https://developers.facebook.com/docs/graph-api/reference/user/picture/

Possible GET parameters for the URL can be found here: https://developers.facebook.com/docs/graph-api/reference/user/picture/
