如何使用MediaStore获取音频文件的缩略图

String selection = MediaStore.Audio.Media.IS_MUSIC + " != 0";

    String[] projection = {
            MediaStore.Audio.Media._ID,
            MediaStore.Audio.Media.ARTIST,
            MediaStore.Audio.Media.TITLE,
            MediaStore.Audio.Media.DATA,
            MediaStore.Audio.Media.DISPLAY_NAME,
            MediaStore.Audio.Media.DURATION,
            MediaStore.Audio.Media.YEAR
    };
    cursor = getBaseContext().getContentResolver().query(MediaStore.Audio.Media.EXTERNAL_CONTENT_URI,
            projection, selection, null, null);
    while(cursor.moveToNext()) {

        name.add(cursor.getString(4));
        path.add(cursor.getString(3));
        duration.add(cursor.getString(5));
    }
