Question

How to change the color of a Delphi listview line / Android ?

To have the color changed as any condition is true:

entao

Answer 1

Add a component TListView.

In our example we will popular the Listview at the event FormCreate:

var
  i, j : Integer;
begin
  for i := 1 to 10 do
    with Listview1.Items.Add do begin
      Caption := 'Item '+ IntToStr(i);
      for j := 1 to 3 do
        Subitems.Add('SubItem '+IntToStr(i)+IntToStr(j));
    end;

At the event OnCustomDrawItem of the component TListView:

  if Odd(item.index) then
    Listview1.Canvas.Brush.Color := clred//Todas as linhas Ímpares
  else
    ListView1.Canvas.Brush.Color := clWhite;//Todas as linhas pares

Now just use your imagination and start adding the Conditions!
