android - 从 Facebook Graph-API 获取用户图像

Question

我想在 ListView 中显示用户的个人资料图片。当我尝试从 android 调用 graph-api 来检索图像时，我总是收到以下错误。

java.io.IOException: Hostname <fbcdn-profile-a.akamaihd.net> was not verified

    at com.facebook.android.Util.openUrl(Util.java:200)
    at com.facebook.android.Facebook.request(Facebook.java:559)

这是我使用的代码:

private static void retrieveProfilePicture(String userId) throws MalformedURLException, IOException{
        facebook = FacebookHelper.getInstance();
        Bundle bundle = new Bundle();
        bundle.putString(Facebook.TOKEN, facebook.getAccessToken());
        Object picture = facebook.request("/"+userId+"/picture", bundle, "GET");

当我在浏览器中执行相同的调用 (https://graph.facebook.com//picture?access_token=) 时，我会在这样的 url 上返回图像https://fbcdn-profile-a.akamaihd.net/...

图片以哪种格式发送给我？带有图像引用 (url) 的 JSON？

Answer 1

 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);

其中 ID 是您的个人资料 ID。
