添加在侧边栏的Windows Phone 8.1应用程序 [英] Add a sidebar in Windows Phone 8.1 application

问题描述

我建立的Windows Phone 8.1应用程序，我希望像Android应用侧边栏。我该怎么办呢？

I'm building Windows Phone 8.1 application and I want a sidebar like in android apps. How can I do it?

我试过的此内容例子，但不编译和操纵事件的不火。

I tried this example, but doesn't compile and manipulation event's do not fire.

推荐答案

下面是速度的处理很简单的例子。

Here is very simple example with velocity handling.

请一定要设置网格的操作属性到所有。

Make sure to set grid's Manipulation property to All.

从深橙红更改网格的背景透明。

XAML

<Canvas Name="RootCanvas">
    <Canvas.Resources>
        <Storyboard x:Name="MoveAnimation">
            <DoubleAnimation Duration="0:0:0.2" To="0" Storyboard.TargetProperty="(Canvas.Left)" Storyboard.TargetName="Sidebar" d:IsOptimized="True" />
        </Storyboard>
    </Canvas.Resources>

    <Grid Name="Sidebar" Background="DarkSalmon" Width="360" Height="640" Canvas.Left="-340" ManipulationDelta="Sidebar_ManipulationDelta" ManipulationMode="All" ManipulationCompleted="Sidebar_ManipulationCompleted">
        <Grid Background="DarkSlateBlue" Margin="0,0,20,0">
            <StackPanel Orientation="Vertical">
                <Button Content="Mailbox" />
                <Button Content="Calendar" />
                <Button Content="Tasks" />
                <Button Content="Documents" />
            </StackPanel>
        </Grid>
    </Grid>
</Canvas>

private bool _triggerCompleted;

    private const double SideMenuCollapsedLeft = -340;
    private const double SideMenuExpandedLeft = 0;

    private void Sidebar_ManipulationDelta(object sender, ManipulationDeltaRoutedEventArgs e)
    {
        _triggerCompleted = true;

        double finalLeft = Canvas.GetLeft(Sidebar) + e.Delta.Translation.X;
        if (finalLeft < -340 || finalLeft > 0)
            return;

        Canvas.SetLeft(Sidebar, finalLeft);

        if (e.IsInertial && e.Velocities.Linear.X > 1)
        {
            _triggerCompleted = false;
            e.Complete();
            MoveLeft(SideMenuExpandedLeft);
        }

        if (e.IsInertial && e.Velocities.Linear.X < -1)
        {
            _triggerCompleted = false;
            e.Complete();
            MoveLeft(SideMenuCollapsedLeft);
        }

        if (e.IsInertial && Math.Abs(e.Velocities.Linear.X) <= 1)
            e.Complete();
    }

    private void Sidebar_ManipulationCompleted(object sender, ManipulationCompletedRoutedEventArgs e)
    {
        if (_triggerCompleted == false)
            return;

        double finalLeft = Canvas.GetLeft(Sidebar);

        if (finalLeft > -170)
            MoveLeft(SideMenuExpandedLeft);
        else
            MoveLeft(SideMenuCollapsedLeft);
    }

    private void MoveLeft(double left)
    {
        double finalLeft = Canvas.GetLeft(Sidebar);

        Storyboard moveAnivation = ((Storyboard)RootCanvas.Resources["MoveAnimation"]);
        DoubleAnimation direction = ((DoubleAnimation)((Storyboard)RootCanvas.Resources["MoveAnimation"]).Children[0]);

        direction.From = finalLeft;

        moveAnivation.SkipToFill();

        direction.To = left;

        moveAnivation.Begin();
    }
