我正在尝试在我的应用程序中显示联系人图片，但我得到的是仅手动添加的图片，而不是与 facebook 同步的图片.如何解决这个问题?下面是我的代码:

I am trying to show contact pictures in my application but I am getting pictures of those who were added manually only and not those which are synced with facebook. How to work around this? Here is my code below:

Uri uri = ContentUris.withAppendedId(ContactsContract.Contacts.CONTENT_URI, Long.parseLong(PhotoId));
InputStream input = ContactsContract.Contacts.openContactPhotoInputStream(context.getContentResolver(), uri);
return BitmapFactory.decodeStream(input);

推荐答案

它不适用于仅从 FB 同步的联系人.您需要使用 FB graph API 并从那里获取照片；并且您需要知道联系人的 Facebook 名称.

It doesn't work for contacts that are synced from FB only. You'll need to use the FB graph API and fetch the photo from there; and you need to know the contacts facebook name.

 Bitmap contactPhoto = getImageBitmap("http://graph.facebook.com/mathiaslin/picture?type=square");

 final private static Bitmap getImageBitmap(String url) {
    Bitmap bm = null;
    try {
        URLConnection conn = new URL(url).openConnection();
        conn.connect();
        InputStream is = conn.getInputStream();
        BufferedInputStream bis = new BufferedInputStream(is);
        bm = BitmapFactory.decodeStream(bis);
        bis.close();
        is.close();
    } catch (IOException e) {
        Log.e(TAG, "Error getting bitmap", e);
    }
    return bm;
}
