AlbumAdapter.cs

public class AlbumAdapter : BaseAdapter<Albums>

    {

        public List<Albums> albumData;

        public List<Albums> _items;

        Activity context;





        public AlbumAdapter(Activity context, IEnumerable<Albums> albumData)

        {

            _items = albumData.OrderBy(s => s.AlbumName).ToList();



            this.context = context;

        }





        public override Albums this[int position]

        {

            get

            {

                return _items[position];

            }

        }



        public override int Count

        {

            get

            {

                return _items.Count;

            }

        }





        public override long GetItemId(int position)

        {

            return position;

        }



        public override View GetView(int position, View convertView, ViewGroup parent)

        {

            var view = convertView;

            var albums = _items[position];

            AlbumHolder holder;



            if (view == null)

            {



                view = LayoutInflater.From(parent.Context).Inflate(Resource.Layout.album_gridview_adapter, parent, false);



                var albumImage = view.FindViewById<ImageView>(Resource.Id.albumImageView);

                var albumName = view.FindViewById<TextView>(Resource.Id.albumName);

                albumName.SetTextColor(Color.Black);





                view.Tag = new AlbumHolder()

                {

                    AlbumCover = albumImage,

                    AlbumName = albumName

                };



                holder = (AlbumHolder)view.Tag;

                holder.AlbumCover.SetImageBitmap(ByteArrayToImageSourceConverter.ImageConverter(_items[position].AlbumCover));

                holder.AlbumName.Text = _items[position].AlbumName;

            }

            else

            {

                holder = (AlbumHolder)view.Tag;

            }



            return view;

        }



    }

ByteArrayToImageSourceConverter : to convert byte data into bitmap

 public static class ByteArrayToImageSourceConverter

    {



        public static Bitmap ImageConverter(byte albumImage)

        {

            Bitmap bitmap = BitmapFactory.DecodeByteArray(albumImage, 0, albumImage.Length);



            return bitmap;

        }

    }

here the output:

and how the above screen to convert like this:
