我要显示用户在列表视图资料图片。 当我尝试调用图形-API从Android的检索图像，我总是得到下面的错误。

  java.io.IOException异常：主机名＆LT; fbcdn-profile-a.akamaihd.net＆GT;未验证
    在org.apache.harmony.luni.internal.net.www.protocol.http.HttpConnection.getSecureSocket(HttpConnection.java:170)
    在org.apache.harmony.luni.internal.net.www.protocol.https.HttpsURLConnection$HttpsEngine.connect(HttpsURLConnection.java:398)
    在org.apache.harmony.luni.internal.net.www.protocol.http.HttpURLConnection.sendRequest(HttpURLConnection.java:1224)
    在org.apache.harmony.luni.internal.net.www.protocol.http.HttpURLConnection.doRequestInternal(HttpURLConnection.java:1558)
    在org.apache.harmony.luni.internal.net.www.protocol.http.HttpURLConnection.doRequest(HttpURLConnection.java:1551)
    在org.apache.harmony.luni.internal.net.www.protocol.http.HttpURLConnection.getInputStream(HttpURLConnection.java:1052)
    在org.apache.harmony.luni.internal.net.www.protocol.https.HttpsURLConnection.getInputStream(HttpsURLConnection.java:252)
    在com.facebook.android.Util.openUrl（Util.java:200）
    在com.facebook.android.Facebook.request（Facebook.java:559）
 

这是我所用的code：

 私有静态无效retrieveProfilePicture（字符串userid）抛出MalformedURLException的，IOException异常{
        Facebook的= FacebookHelper.getInstance（）;
        束束=新包（）;
        bundle.putString（Facebook.TOKEN，facebook.getAccessToken（））;
        对象画面= facebook.request（/+用户id +/图片，​​捆绑，GET）;
 

当我做同样的呼吁在浏览器（https://graph.facebook.com//picture?access_token=），然后我得到返回的图像上像这样的网址 HTTPS：//fbcdn-profile-a.akamaihd.net / ...

在哪种格式交付给我的形象呢？ JSON与裁判图像（URL）？

  ImageView的user_picture;
 userpicture =（ImageView的）findViewById（R.id.userpicture）;
 URL img_value = NULL;
 img_value =新的URL（http://graph.facebook.com/+编号+？/图像类型=大）;
 位图mIcon1 = BitmapFactory.de codeStream（img_value.openConnection（）的getInputStream（））;
 userpicture.setImageBitmap（mIcon1）;
 

其中id是您的个人资料的ID。

有关进一步的细节检查这个参考图形API

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)

This is the code used by me:

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");

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/...

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

 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);

Where ID is one your profile ID.
