1、通过listview.ScrollIntoView()方法实现：
滚动到顶端：listview.ScrollIntoView(listview.Items[0]);
滚动到低端：
int count = listview.Items.Count;
int index = count - 1; listview.ScrollIntoView(listview.Items[index]);
滚动到指定位置：listview.ScrollIntoView(listview.Items[index]);
2、通过控制listview内部的ScrollView控件实现：
Border bor = VisualTreeHelper.GetChild(listview, 0) as Border; //listview内部第一层为Border容器
ScrollViewer sview = bor.Child as ScrollViewer; //border内部的child即为scrollview,正是我们接下来操作需要的控件
OK！接下来可以实现之前的功能：
滚动到顶端：sview.ScrollToTop();
滚动到低端：sview.ScrollToBottom();
滚动到指定位置：sview.ScrollToVerticalOffset(positin); //position为垂直方向滚动的高度，同之前的index不同
