Xaml Windows8AppBar覆盖页面内容；我想要挤牛奶

WinRT中的Page.appbar是否有一些技巧可以挤压/移动页面的内容，而不是越过内容的顶部？

您可以，但需要编写一些代码才能做到这一点

使用可视状态的我的版本：

<Page.BottomAppBar>
    <AppBar
        x:Name="bottomAppBar"
        Opened="OnBottomAppBarOpened"
        Closed="OnBottomAppBarClosed">
        <StackPanel
            Orientation="Horizontal">
            <Button
                Style="{StaticResource PlayAppBarButtonStyle}" />
        </StackPanel>
    </AppBar>
</Page.BottomAppBar>
<Grid
    Background="{StaticResource ApplicationPageBackgroundThemeBrush}">
    <VisualStateManager.VisualStateGroups>
        <VisualStateGroup
            x:Name="AppBarPushStates">
            <VisualState
                x:Name="AppBarClosed">
                <Storyboard>
                    <DoubleAnimation
                        Storyboard.TargetName="pushedContentTransform"
                        Storyboard.TargetProperty="Y"
                        To="0"
                        Duration="0:0:0.2">
                        <DoubleAnimation.EasingFunction>
                            <CubicEase
                                EasingMode="EaseOut" />
                        </DoubleAnimation.EasingFunction>
                    </DoubleAnimation>
                </Storyboard>
            </VisualState>
            <VisualState
