简单的动画定义及调用

定义名字

<phone:PhoneApplicationPage 
    x:Name="mainPage"

在 xaml 定义动画资源

    <phone:PhoneApplicationPage.Resources>
        <Storyboard x:Name="GoLeft">
            <DoubleAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.Projection).(PlaneProjection.GlobalOffsetX)" Storyboard.TargetName="mainPage">
                <EasingDoubleKeyFrame KeyTime="0" Value="0"/>
                <EasingDoubleKeyFrame KeyTime="0:0:0.2" Value="-500"/>
            </DoubleAnimationUsingKeyFrames>
        </Storyboard>
        <Storyboard x:Name="GoRight">
            <DoubleAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.Projection).(PlaneProjection.GlobalOffsetX)" Storyboard.TargetName="mainPage">
                <EasingDoubleKeyFrame KeyTime="0" Value="0"/>
                <EasingDoubleKeyFrame KeyTime="0:0:0.2" Value="500"/>
            </DoubleAnimationUsingKeyFrames>
        </Storyboard>
        <Storyboard x:Name="ComeLeft">
            <DoubleAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.Projection).(PlaneProjection.GlobalOffsetX)" Storyboard.TargetName="mainPage">
                <EasingDoubleKeyFrame KeyTime="0" Value="-500"/>
                <EasingDoubleKeyFrame KeyTime="0:0:0.2" Value="0"/>
            </DoubleAnimationUsingKeyFrames>
        </Storyboard>
        <Storyboard x:Name="ComeRight">
            <DoubleAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.Projection).(PlaneProjection.GlobalOffsetX)" Storyboard.TargetName="mainPage">
                <EasingDoubleKeyFrame KeyTime="0" Value="500"/>
                <EasingDoubleKeyFrame KeyTime="0:0:0.2" Value="0"/>
            </DoubleAnimationUsingKeyFrames>
        </Storyboard>
    </phone:PhoneApplicationPage.Resources>
    <phone:PhoneApplicationPage.Projection>
        <PlaneProjection/>
    </phone:PhoneApplicationPage.Projection>

调用动画

                    GoLeft.Completed += new EventHandler((sender, eventargs) =>
                        {
                            ComeRight.Begin(); //从右回
                        });
                    GoRight.Completed += new EventHandler((sender, eventargs) =>
                        {
                            ComeLeft.Begin(); //从左回
                        });
                    if (tmpstartid > startid)
                        GoLeft.Begin(); //向左走
                        else if (tmpstartid < startid) GoRight.Begin(); //向右走
