首发 手把手教你制作 Windows8 应用程序内部的 hubtile （动态瓷砖控件） MetroStyle（转）

http://blog.csdn.net/wangrenzhu2011/article/details/8175492 （转）

在metro 风格中 动态磁贴是他的精髓

在wp7 的开发中 我们可以使用hubtile 来制作类似效果

但是在 win8 中并不具备这个功能，

下面我们来通过扩展GridViewItem 来实现  PictureHubTile

<GridViewItem
    x:Class="App1.HubTile"

            });
        }
    }
}

 

该样例代码中 我使用了awaitUI 来实现对动画执行的监控，

程序逻辑并不复杂，通过随机的timer 来切换图片 实现

开始菜单的效果

demo 稍后上传

最终效果图：
