(SOLVED) jListView image question

Hi all, I'm experimenting with the jListView object. And in addition
to the text I would like to put an image on each line, I found a way
to do this, but it allows me to put the same image on all lines. But I
want to change the image based on criteria at runtime. To understand
it, it would be enough for me to see that on even lines it puts an
image and on odd lines it puts another image.
Can you help me? I enclose a very small project to show where I have
arrived.

Solved with this code

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i procedure
TAndroidModule1.ListView1DrawItemBitmap(Sender: TObject;  itemIndex:
integer; itemCaption: string; out bimap: JObject);begin     if
((itemIndex mod 2)=0) then     begin        bimap :=
Self.jImageList1.GetBitmap(0)     end     else     begin         
bimap := Self.jImageList1.GetBitmap(1);     end;end;
