Burada ortak katmanda oluşturduğum Entry'i çağırarak verdiğim özelliklere göre revize edeceğim.

EntryRendererAndroid.cs

namespace UISampleApp.Droid.Renderers
{
    public class ImageEntryRenderer : EntryRenderer
    {
        ImageEntry element;
	public ImageEntryRenderer(Context context) : base(context)
        {

        }
        protected override void OnElementChanged(ElementChangedEventArgs<Entry> e)
        {
            base.OnElementChanged(e);

            if (e.OldElement != null || e.NewElement == null)
                return;

            element = (ImageEntry)this.Element;


			var editText = this.Control;
            if (!string.IsNullOrEmpty(element.Image))
            {
				switch (element.ImageAlignment)
				{
					case ImageAlignment.Left:
						editText.SetCompoundDrawablesWithIntrinsicBounds(GetDrawable(element.Image), null, null, null);
						break;
					case ImageAlignment.Right:
						editText.SetCompoundDrawablesWithIntrinsicBounds(null, null, GetDrawable(element.Image), null);
						break;
				}
            }
            editText.CompoundDrawablePadding = 25;
            Control.Background.SetColorFilter(element.LineColor.ToAndroid(), PorterDuff.Mode.SrcAtop);
        }

		private BitmapDrawable GetDrawable(string imageEntryImage)
		{
            int resID = Resources.GetIdentifier(imageEntryImage, "drawable",this.Context.PackageName);
			var drawable = ContextCompat.GetDrawable(this.Context, resID);
			var bitmap = ((BitmapDrawable)drawable).Bitmap;

			return new BitmapDrawable(Resources, Bitmap.CreateScaledBitmap(bitmap, element.ImageWidth * 2, element.ImageHeight * 2, true));
		}

    }
