从 Facebook Graph-API 获取用户图片 [英] Get user image from Facebook Graph-API

问题描述

我想在列表视图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，总是出现以下错误.

I want to show the users profile picture in a list view. When I try to call the graph-api from android to retrieve the image, I always get the following error.

java.io.IOException: Hostname <fbcdn-profile-a.akamaihd.net> was not verified
    at org.apache.harmony.luni.internal.net.www.protocol.http.HttpConnection.getSecureSocket(HttpConnection.java:170)

    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(https://graph.facebook.com//picture?access_token=)中执行相同的调用时，我会在这样的网址上返回图像https://fbcdn-profile-a.akamaihd.net/...

When I do the same call in the browser (https://graph.facebook.com//picture?access_token=), then I get the image returned on a url like this https://fbcdn-profile-a.akamaihd.net/...

图片以哪种格式发送给我?带有图像(url)引用的 JSON?

In which format is the image delivered to me? JSON with a ref to image (url)?

推荐答案

 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.

Where ID is one your profile ID.
