1、通過listview.ScrollIntoView()方法實現：
滾動到頂端：listview.ScrollIntoView(listview.Items[0]);
滾動到低端：
int count = listview.Items.Count;
int index = count - 1; listview.ScrollIntoView(listview.Items[index]);
滾動到指定位置：listview.ScrollIntoView(listview.Items[index]);
2、通過控制listview內部的ScrollView控件實現：
Border bor = VisualTreeHelper.GetChild(listview, 0) as Border; //listview內部第一層為Border容器
ScrollViewer sview = bor.Child as ScrollViewer; //border內部的child即為scrollview,正是我們接下來操作需要的控件
OK！接下來可以實現之前的功能：
滾動到頂端：sview.ScrollToTop();
滾動到低端：sview.ScrollToBottom();
滾動到指定位置：sview.ScrollToVerticalOffset(positin); //position為垂直方向滾動的高度，同之前的index不同
