delphi中的ListView怎么用啊？详细点好不好

//增加
i := ListView1.Items.Count;
with ListView1 do
begin
ListItem:=Items.Add;
ListItem.Caption:= IntToStr(i);
ListItem.SubItems.Add('第 '+IntToStr(i)+' 行');
ListItem.SubItems.Add('第三列内容');
end;

//按标题删除
for i:=ListView1.Items.Count-1 downto 0 Do
if ListView1.Items[i].Caption = Edit1.Text then
begin
ListView1.Items.Item[i].Delete(); //删除当前选中行
end;

//选中一行
if ListView1.Selected <> nil then
Edit1.Text := ListView1.Selected.Caption;

// listview1.Items[Listview1.Items.Count -1].Selected := True;
// listview1.Items[Listview1.Items.Count -1].MakeVisible(True);
procedure TForm1.Button2Click(Sender: TObject); // 选择第一条
begin
listview1.SetFocus;
listview1.Items[0].Selected := True;
end;

procedure TForm1.Button1Click(Sender: TObject); // 选择最后一条
begin
