Well, I didn't find SetBKImage with a standard ListView, but you can use the method i just tried ... set owner draw to true and add an image component containing the bmp-Image you want to have as background, then use the OnCustomDraw event to draw the image as background

procedure TForm1.ListView1CustomDraw(Sender: TCustomListView;
  const ARect: TRect; var DefaultDraw: Boolean);
var DestRect, SrcRect : TRect;
begin
  DestRect := Rect(0,0,ListView1.width, Listview1.Height);
  SrcRect := Rect(0,0,Image1.Width,Image1.Height);
  ListView1.Canvas.CopyRect(DestRect,image1.picture.Bitmap.Canvas, SrcRect);
end;

If you want to do it dynamically you can use practically the same. the image with the picture should not be set invisible when copying the image but afterwards you can set it invisible.
You should change it a bit if it doesn't fit exactly your needs.

a little bit smaller ;-)

procedure TForm1.ListView1CustomDraw(Sender: TCustomListView;
 const ARect: TRect; var DefaultDraw: Boolean);
Begin
 DestRect := Rect(0,0,ListView1.width, Listview1.Height);
 SrcRect := Rect(0,0,Image1.Width,Image1.Height);
 ListView1.Canvas.CopyRect(Listview1.ClientRect.DestRect,image1.picture.Bitmap.Canvas, Image.ClientRect);
end;
