请问：怎么让Listview某一行,某一列文字，显示特定的颜色？

[ATmega32]

请问：
1.怎么让Listview第X列文字显示特定颜色？（25）
2.怎么让Listview第Y行文字显示特定颜色？（25）
2.怎么让Listview 第X列，第Y行（交汇）文字显示特定颜色？（50）

第0列显示不行，其他都行。

怎么让第0列显示特别颜色，
第0列第Y行显示特定颜色？？

[周药师]

//画第一列的用个笨方法吧

//先把所有的列画上你要的颜色，然后把除了第一列的其它列全部恢复颜色，
//这样效果就是只有第一列有颜色了
void __fastcall TForm1::ListView1AdvancedCustomDrawItem(
      TCustomListView *Sender, TListItem *Item, TCustomDrawState State,
      TCustomDrawStage Stage, bool &DefaultDraw)
{
      //全部画上
      ListView1->Canvas->Brush->Color   =   clWhite   ;
      ListView1->Canvas->Font->Color    =   clBlue;    //字体为  clBlue 颜色
}

void __fastcall TForm1::ListView1CustomDrawSubItem(TCustomListView *Sender,
      TListItem *Item, int SubItem, TCustomDrawState State,
      bool &DefaultDraw)
{
      //还原除第一列的其它列
      ListView1->Canvas->Brush->Color   =   clWhite;
      ListView1->Canvas->Font->Color    =   clBlack;
}

[周药师]

//同样 要 第0列第Y行显示特定颜色？？ 加个判断

//0列1行
void __fastcall TForm1::ListView1AdvancedCustomDrawItem(
      TCustomListView *Sender, TListItem *Item, TCustomDrawState State,
      TCustomDrawStage Stage, bool &DefaultDraw)
{
   if(Item->Index==1) //1 行 
    {
      ListView1->Canvas->Brush->Color   =   clWhite   ;
     ListView1->Canvas->Font->Color    =   clBlue;    //字体为  clBlue 颜色
    }
}

void __fastcall TForm1::ListView1CustomDrawSubItem(TCustomListView *Sender,
      TListItem *Item, int SubItem, TCustomDrawState State,
      bool &DefaultDraw)
{
      //还原除第一列的其它列
      ListView1->Canvas->Brush->Color   =   clWhite;
     ListView1->Canvas->Font->Color    =   clBlack;
}

多谢，还有个问题，

//1行2列交汇单元格的颜色
void __fastcall TForm1::ListView1AdvancedCustomDrawSubItem(
TCustomListView *Sender, TListItem *Item, int SubItem,
TCustomDrawState State, TCustomDrawStage Stage, bool &DefaultDraw)
{
if(Item->Index==1)//1行
{
if(SubItem==2)//2列
{
ListView1->Canvas->Brush->Color = clWhite ;
ListView1->Canvas->Font->Color = clBlue; //字体为 clBlue 颜色
}
else
{
ListView1->Canvas->Brush->Color = clWhite;
ListView1->Canvas->Font->Color = clBlack; //字体为 clBlack 颜色
}
}
}

某一行只有一列能显示特别颜色，怎么弄可以让某一行多个列（可变）显示特殊颜色？？

你多加一个判断就多画一个

void __fastcall TForm1::ListView1AdvancedCustomDrawSubItem( 
      TCustomListView *Sender, TListItem *Item, int SubItem, 
      TCustomDrawState State, TCustomDrawStage Stage, bool &DefaultDraw) 
{ 
  if(Item->Index==1)//1行 
  { 
    if(SubItem==1||SubItem==2||SubItem==3)//1、2、3列 
    { 
      ListView1->Canvas->Brush->Color  =  clWhite  ; 
      ListView1->Canvas->Font->Color    =  clBlue;    //字体为  clBlue 颜色 
    } 
    else 
    { 
      ListView1->Canvas->Brush->Color  =  clWhite; 
      ListView1->Canvas->Font->Color    =  clBlack;    //字体为  clBlack 颜色 
    } 
  } 
}

需要在ListView的DrawItem事件中进行处理。
如：
DELPHI代码
if Item.index = Y then // 第Y行
begin
self.Canvas.Brush.Color := clBlue;
end
else
begin
self.Canvas.Brush.Color := clRed;
end;

for i := 0 to Item.SubItems.Count - 1 do
begin
if i = X then// 第X列
begin
self.Canvas.Brush.Color := clRed;
end;
end

通过。

不行啊，（所有行，所有列都变成红色了）

[regersubadm]

Var
oldColor:TColor;

oldColor = slef.canvas.Brush.Color ;
for i := 0 to Item.SubItems.Count - 1 do
begin
if i = 2 then
begin
self.Canvas.Brush.Color := clRed;
end
else
begin
self.Canvas.Brush.Color := oldColor;
end;
end;
