Windows phone 7 phone7中的闪烁图像动画

在wp7中创建闪烁图像动画的最佳方法是什么？是否有源代码可用的示例？ （或）

我有一组4张图片，每一张都要在几秒钟内换成另一张。这有可能吗？

我已经为您编写了这段代码。试试看

在xaml中，添加一个带有图像控件和按钮的画布，其中包含一个故事板

  <Canvas Height="220" HorizontalAlignment="Left" Margin="79,29,0,0" Name="canvas1" VerticalAlignment="Top" Width="401" Grid.Row="1" >
        <Canvas.Resources>

            <Storyboard x:Name="myStoryboard">
                <DoubleAnimation
    Storyboard.TargetName="image"
    Storyboard.TargetProperty="Opacity"
    From="1.0" To="0.0" Duration="0:0:1" 
     />
            </Storyboard>

        </Canvas.Resources>


        <Image Name="image" Width="200" Height="173"></Image>
        <Button Content="Button" Height="54"   HorizontalAlignment="Left" Margin="388,113,0,0" Name="button1" VerticalAlignment="Top" Width="97" Grid.Row="1" Click="button1_Click" Canvas.Left="-97" Canvas.Top="-26"/>
        </canvas>

可以使用单个图像制作闪烁动画

<Ellipse x:Name="light1" Grid.Column="1" Grid.Row="1" Fill="#FFF7810A" HorizontalAlignment="Left" Margin="109,9,0,8" Stroke="Black" Width="100" d:LayoutOverrides="GridBox"/>

<Ellipse x:Name="light2" Grid.Row="1" Fill="#FFF7810A" Margin="0,9,106,8" Stroke="Black" HorizontalAlignment="Right" Width="100" d:LayoutOverrides="GridBox"/>

在第二步中，我将动画应用到这两个相反方向的圆圈上，这样当一个圆圈淡出另一个圆圈时，另一个圆圈淡出（类似于两个闪烁的道路工作灯的错觉）

<Ellipse x:Name="light1" Grid.Column="1" Grid.Row="1" Fill="#FFF7810A" HorizontalAlignment="Left" Margin="109,9,0,8" Stroke="Black" Width="100" d:LayoutOverrides="GridBox"/>

<Ellipse x:Name="light2" Grid.Row="1" Fill="#FFF7810A" Margin="0,9,106,8" Stroke="Black" HorizontalAlignment="Right" Width="100" d:LayoutOverrides="GridBox"/>

<Grid.Triggers>
<EventTrigger RoutedEvent="Canvas.Loaded">
<BeginStoryboard>
    <Storyboard>
        <DoubleAnimation Storyboard.TargetName="light1"        Storyboard.TargetProperty="Opacity" From="0.5" To="1" Duration="0:0:1.5"  AutoReverse="True" RepeatBehavior="Forever" />
        <DoubleAnimation Storyboard.TargetName="light2"  Storyboard.TargetProperty="Opacity" From="1" To="0.5" Duration="0:0:1.5" AutoReverse="True" RepeatBehavior="Forever" />
    </Storyboard>
</BeginStoryboard>
  </EventTrigger>
</Grid.Triggers>
