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
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" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="using:App1" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" mc:Ignorable="d" x:Name="gridViewItem" d:DesignHeight="150" d:DesignWidth="150"> <GridViewItem.Resources> <Storyboard x:Name="UpperSecStoryboard"> <DoubleAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.RenderTransform).(CompositeTransform.TranslateY)" Storyboard.TargetName="SecImg"> <SplineDoubleKeyFrame KeyTime="0:0:1.2" Value="-150" KeySpline="0.29,0.88,0,1"/> </DoubleAnimationUsingKeyFrames> <DoubleAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.RenderTransform).(CompositeTransform.TranslateY)" Storyboard.TargetName="FirstImg"> <SplineDoubleKeyFrame KeyTime="0:0:1.2" Value="150" KeySpline="1,0,1,0"/> </DoubleAnimationUsingKeyFrames> </Storyboard> <Storyboard x:Name="UpperFirstStoryboard"> <DoubleAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.RenderTransform).(CompositeTransform.TranslateY)" Storyboard.TargetName="SecImg"> <SplineDoubleKeyFrame KeyTime="0:0:1.2" Value="0" KeySpline="1,0,1,0"/> </DoubleAnimationUsingKeyFrames> <DoubleAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.RenderTransform).(CompositeTransform.TranslateY)" Storyboard.TargetName="FirstImg"> <SplineDoubleKeyFrame KeyTime="0:0:1.2" Value="0" KeySpline="0.29,0.88,0,1"/> </DoubleAnimationUsingKeyFrames> </Storyboard> </GridViewItem.Resources> <Grid Width="{Binding Width, ElementName=gridViewItem}" Height="{Binding Height, ElementName=gridViewItem}"> <Canvas x:Name="PART_LayoutRoot" > <StackPanel x:Name="PART_Panel"> <Canvas Height="{Binding Height, ElementName=gridViewItem}" x:Name="FirstImg"> <Grid x:Name="PART_FirstContent"> <Image x:Name="Img1" Width="{Binding Width, ElementName=gridViewItem}" Height="{Binding Height, ElementName=gridViewItem}" Stretch="UniformToFill" VerticalAlignment="Center"> </Image> </Grid> <Canvas.RenderTransform> <CompositeTransform/> </Canvas.RenderTransform> </Canvas> <Canvas x:Name="SecImg" Height="{Binding Height, ElementName=gridViewItem}"> <Grid x:Name="SecGrid" Background="Red"> <Image x:Name="Img2" Width="{Binding Width, ElementName=gridViewItem}" Height="{Binding Height, ElementName=gridViewItem}" Stretch="UniformToFill" VerticalAlignment="Center"> </Image> </Grid> <Canvas.RenderTransform> <CompositeTransform/> </Canvas.RenderTransform> </Canvas> </StackPanel> </Canvas> <ContentPresenter Content="1111" VerticalAlignment="Bottom" HorizontalAlignment="Stretch" x:Name="PART_Title" Margin="0,0,10,7" /> </Grid></GridViewItem>

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
