• Windows Phone开发经验谈(8)手势切换的方式(下)


         继上篇Windows Phone开发经验谈(7)-手势切换的方式(上)后,我继续来给大家说说如何在切换的过程中加入动画...

         首先来说说思路首先一个页面的切换需要有过渡动画,我们可以考虑用3个不同的容器之间进行切换.默认的要显示第2的这个容器.左边滑动的时候第1个容器跑到中间 右边滑动的时候第2个容器跑到中间.

        xaml代码如下:

    <phone:PhoneApplicationPage 
        x:Class="PhoneApp3.MainPage"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

            private void GestureListener_Flick(object sender, Microsoft.Phone.Controls.FlickGestureEventArgs e)
            {
                if (e.Direction == System.Windows.Controls.Orientation.Horizontal)
                {
                    if (e.HorizontalVelocity > 0.0)
                    {
                        prev();
                    }
                    else
                    {
                        next();
                    }
                }
            }
        }
    }
    

    上面的代码就是首先初始化让中间的位置的显示,然后上一个就是左边的移动到中间来让他显示,下一个是右边的移动到中间让他显示...

    原理很简单..项目我也打包好,大家研究一下.PhoneApp3.rar
