Android - 获取Facebook个人资料图片 [英] Android - get facebook profile picture

问题描述

我不知道为什么，但是当我尝试获取用户的个人资料图片时，我总是变空。我需要设置一些特定权限才能访问？

I don't know why, but I am always getting null when I try to get the profile picture of the user. Do I need to set some specific permissions to get access?

以下是我的方法：

public static Bitmap getFacebookProfilePicture(String userID) throws SocketException, SocketTimeoutException, MalformedURLException, IOException, Exception
{
   String imageURL;

   Bitmap bitmap = null;
   imageURL = "http://graph.facebook.com/"+userID+"/picture?type=large";
   InputStream in = (InputStream) new URL(imageURL).getContent();
   bitmap = BitmapFactory.decodeStream(in);

   return bitmap;
}

Bitmap bitmap = getFacebookProfilePicture(userId);

我变空我不知道为什么？任何帮助都是可以理解的。

I am getting null. I don't know the reason why? Any help is appreciable.

推荐答案

这应该有效：

public static Bitmap getFacebookProfilePicture(String userID){
    URL imageURL = new URL("https://graph.facebook.com/" + userID + "/picture?type=large");
    Bitmap bitmap = BitmapFactory.decodeStream(imageURL.openConnection().getInputStream());

    return bitmap;
}

Bitmap bitmap = getFacebookProfilePicture(userId);

编辑：

在评论中，href =https://stackoverflow.com/questions/19855072/android-get-facebook-profile-picture#comment34682218_19855492> @dvpublic ，图像未被下载的问题是使用https赞成http。

As suggested by @dvpublic in the comments, the problem of image not being downloaded is fixed using by "https" in favour of "http".
