自己写CustomSortProc函数, 以下是我写的一个例子, 单击ListView的Column可正反排序var m_bSort: boolean=false; //...........//回调函数 function CustomSortProc(Item1, Item2: TListItem; ParamSort: integer): integer; stdcall; var txt1,txt2 : string; begin if ParamSort <> 0 then begin txt1 := Item1.SubItems.Strings[ParamSort - 1]; txt2 := Item2.SubItems.Strings[ParamSort - 1]; if m_bSort then begin //这个变量来控制正反排序 Result := CompareText(txt1,txt2); end else begin Result := -CompareText(txt1,txt2); end; end else begin if m_bSort then begin Result := CompareText(Item1.Caption,Item2.Caption); end else begin Result := -CompareText(Item1.Caption,Item2.Caption); end; end; end;procedure TForm1.ListView1ColumnClick(Sender: TObject; Column: TListColumn); begin ListView1.CustomSort(@CustomSortProc, Column.Index); m_bSort := not m_bSort; end;

//...........//回调函数
function CustomSortProc(Item1, Item2: TListItem; ParamSort: integer): integer; stdcall;
var txt1,txt2 : string;

if ParamSort <> 0 then begin
txt1 := Item1.SubItems.Strings[ParamSort - 1];
txt2 := Item2.SubItems.Strings[ParamSort - 1]; if m_bSort then begin //这个变量来控制正反排序
Result := CompareText(txt1,txt2);
end else begin
Result := -CompareText(txt1,txt2);
end;
end else begin
if m_bSort then begin
Result := CompareText(Item1.Caption,Item2.Caption);
end else begin
Result := -CompareText(Item1.Caption,Item2.Caption);
end;
end;
end;procedure TForm1.ListView1ColumnClick(Sender: TObject;
Column: TListColumn);
begin
ListView1.CustomSort(@CustomSortProc, Column.Index);

end;
