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

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

  100. });
  101. }
  102. }
  103. }


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:
