c#中如何在listview中嵌入progressbar显示结果

通过重新绘制ListView来实现，Delphi参考如下Delphi代码： （C#也是一样的）

Delphi(Pascal) codeunit Unit1

interface

uses

Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,

Dialogs, StdCtrls, ComCtrls, ExtCtrls

type

TForm1 = class(TForm)

ListView1: TListView

Timer1: TTimer

procedure FormCreate(Sender: TObject)

procedure ListView1CustomDrawSubItem(Sender: TCustomListView

Item: TListItemSubItem: IntegerState: TCustomDrawState

var DefaultDraw: Boolean)

procedure Timer1Timer(Sender: TObject)

private

{ Private declarations }

FProgress: TListItem

FPostion: Integer

FLength: Integer

FProgressRect: TRect

public

{ Public declarations }

end

var

Form1: TForm1

implementation

{$R *.dfm}

procedure TForm1.FormCreate(Sender: TObject)

begin

FProgress := ListView1.Items.Add

FProgress.Caption := 'temp.txt'

FPostion := 0

FLength := 100

Timer1.Interval := 100

end

procedure DrawProgress(ACanvas: TCanvasARect: TRect

APostion, ALength: Integer)// 想绘制得漂亮些就在这里修改。

begin

ACanvas.Brush.Color := clWindow

ACanvas.FillRect(ARect)

ACanvas.Brush.Color := clHighlight

ACanvas.FillRect(Rect(ARect.Left, ARect.Top + 2,

ARect.Left + Trunc((ARect.Right - ARect.Left) * (APostion / ALength)),

ARect.Bottom - 4))

end

procedure TForm1.ListView1CustomDrawSubItem(Sender: TCustomListView

Item: TListItemSubItem: IntegerState: TCustomDrawState

var DefaultDraw: Boolean)

begin

if FProgress <>Item then Exit

if Item.Index <>0 then Exit

///////Begin 计算进度条绘制的区域

FProgressRect := Item.DisplayRect(drBounds)

FProgressRect.Left := Sender.Column[0].Width

FProgressRect.Right := Sender.Column[1].Width + FProgressRect.Left

///////End 计算进度条绘制的区域

DrawProgress(Sender.Canvas, FProgressRect, FPostion, FLength)

DefaultDraw := False

end

procedure TForm1.Timer1Timer(Sender: TObject)

begin

FPostion := (FPostion + 1) mod FLength

DrawProgress(ListView1.Canvas, FProgressRect, FPostion, FLength)

end

end.

exList就是listview ，其中的每个item中都有一个progressBar

progress是进度；

View v = exList.getChildAt(i)

ProgressBar bar = (ProgressBar) v .findViewById(R.id.manager_loading_progress_bar)

if (bar != null)

bar.setProgress(progress)

我以前的做法是： 在BaseAdapter中每创建一个View时候 就把每一个progressbar加到list中。 当我加载完所有item后， 所有的progressbar都在list中，你想改哪一个就得到哪一个的progressbar不知道对你有没有用？
