如何获取相册缩略图中的Andr​​oid？

我有，我用了这个专辑列表：

I have a list of albums which I got using this:

private List<Album> getAlbums() {
Cursor cur = managedQuery(MediaStore.Audio.Media.EXTERNAL_CONTENT_URI, null, null, null, null);
  List<Album> albums = new ArrayList<Album>();

  if (cur.moveToFirst()) {
   do {
    int albumIdIndex = cur.getColumnIndex(MediaStore.Audio.Media.ALBUM_ID);
    int albumIndex = cur.getColumnIndex(MediaStore.Audio.Media.ALBUM);
    int artistIndex = cur.getColumnIndex(MediaStore.Audio.Media.ARTIST);
    int albumId = cur.getInt(albumIdIndex);
    String name = cur.getString(albumIndex);
    String artist = cur.getString(artistIndex);
    LogUtil.i(TAG, "albumid= " + albumId + ", album= " + name + ", artist=" + artist);

    Album album = new Album(albumId, name, artist);
    if (!albums.contains(album)) {
     albums.add(album);
    }    
   } while (cur.moveToNext());

  }

  return albums;
 }

我用的这个专辑列表中的ListActivity，但我也想拿到专辑的缩略图。

I use this list of albums in a ListActivity, but I also want to get the thumbnails of the Albums.

我知道我可以使用下面的code，以获得实际的作品，但我需要的缩略图，因为我得到的内存，如果我使用完整的图像列表活动：

I know I can use the following code to get the actual artwork, but I need the thumbnails because I get Out Of Memory if I use the full images in a List Activity:

Uri sArtworkUri = Uri.parse("content://media/external/audio/albumart");
Uri uri = ContentUris.withAppendedId(sArtworkUri, album_id);

我看到这个帖子： http://stackoverflow.com/questions/2902232/android-media-thumbnails-serious-issues 但我没有imageId，只有ALBUMID，所以我不认为这会有所帮助。

I saw this post: http://stackoverflow.com/questions/2902232/android-media-thumbnails-serious-issues But I do not have the imageId, only the albumid, so I don't think it helps.
