Windows Phone 导航过渡效果

Introduction
这篇文章我将介绍如何在WP7中创建一个页面过渡动画。我已经在WP7项目中使用XAML代码创建一个过渡动画,最后我们会看到如何用后台代码进行页面过渡动画。

首先需要添加Microsoft.Phone.Controls.Toolkit.dll 引用。

因安装的位置可能有所不同,在我的PC里面的位置是：

C:\Program Files (x86)\Microsoft SDKs\Windows Phone\v7.1\Toolkit

Background
在一个页面导航到另一个页面时首要你要指定页面是如何出现或者消失,页面的过渡动画其实使用StoryBoard来替代

下面将介绍5种过渡效果

•RollTransition

•RotateTransition

•SlideTransition

•SwivelTransition

•TurnstileTransition
除了其他所有的过渡效果都有一个你要选择指定的过渡类型的属性在页面导航时你可以指定向后和向前过渡以下呈现的是四种页面导航过渡类型

Using the code
首先创建一个WP7项目。

然后增加Page1和Page2两个页面

然后在MainPage为Button添加导航到Page1页面代码:

private void button1_Click(object sender, RoutedEventArgs e)
{
NavigationService.Navigate(new Uri("/Page1.xaml",UriKind.Relative));
}
然后在Page1页面中添加导航到Page2页面代码:
private void button1_Click(object sender, RoutedEventArgs e)
{
NavigationService.Navigate(new Uri("/Page2.xaml",UriKind.Relative));
}
在Page1页面中我提供了 In and Out 过渡, 在页面的XAML代码中添加toolkit空间
xmlns:toolkit="clr-namespace:Microsoft.Phone.Controls;assembly=Microsoft.Phone.Controls.Toolkit"
下面是Page1页面进入和离开时过渡动画的XAML代码：
<toolkit:TransitionService.NavigationInTransition>
    <toolkit:NavigationInTransition>
        <toolkit:NavigationInTransition.Backward>
            <toolkit:TurnstileTransition Mode="BackwardIn"/>
        </toolkit:NavigationInTransition.Backward>
        <toolkit:NavigationInTransition.Forward>
            <toolkit:TurnstileTransition Mode="ForwardIn"/>
        </toolkit:NavigationInTransition.Forward>
    </toolkit:NavigationInTransition>
</toolkit:TransitionService.NavigationInTransition>
<toolkit:TransitionService.NavigationOutTransition>
    <toolkit:NavigationOutTransition>
        <toolkit:NavigationOutTransition.Backward>
            <toolkit:TurnstileTransition Mode="BackwardOut"/>
        </toolkit:NavigationOutTransition.Backward>
        <toolkit:NavigationOutTransition.Forward>
            <toolkit:TurnstileTransition Mode="ForwardOut"/>
        </toolkit:NavigationOutTransition.Forward>
    </toolkit:NavigationOutTransition>
</toolkit:TransitionService.NavigationOutTransition>

在Page1页面上面提供的是TurnstileTransition 过渡,Mode 属性指定的是应用的过渡类型
Page1页面完整的XAML代码如下：
<phone:PhoneApplicationPage
    x:Class="WindowsPhoneNavigationTransitions.Page1"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:phone="clr-namespace:Microsoft.Phone.Controls;assembly=Microsoft.Phone"
    xmlns:shell="clr-namespace:Microsoft.Phone.Shell;assembly=Microsoft.Phone"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    xmlns:toolkit="clr-namespace:Microsoft.Phone.Controls;assembly=Microsoft.Phone.Controls.Toolkit"
    FontFamily="{StaticResource PhoneFontFamilyNormal}"
    FontSize="{StaticResource PhoneFontSizeNormal}"
    Foreground="{StaticResource PhoneForegroundBrush}"
    SupportedOrientations="Portrait" Orientation="Portrait"
    mc:Ignorable="d" d:DesignHeight="768" d:DesignWidth="480"
    shell:SystemTray.IsVisible="True">

    <toolkit:TransitionService.NavigationInTransition>
        <toolkit:NavigationInTransition>
            <toolkit:NavigationInTransition.Backward>
                <toolkit:TurnstileTransition Mode="BackwardIn"/>
            </toolkit:NavigationInTransition.Backward>
            <toolkit:NavigationInTransition.Forward>
                <toolkit:TurnstileTransition Mode="ForwardIn"/>
            </toolkit:NavigationInTransition.Forward>
        </toolkit:NavigationInTransition>
    </toolkit:TransitionService.NavigationInTransition>
    <toolkit:TransitionService.NavigationOutTransition>
        <toolkit:NavigationOutTransition>
            <toolkit:NavigationOutTransition.Backward>
                <toolkit:TurnstileTransition Mode="BackwardOut"/>
            </toolkit:NavigationOutTransition.Backward>
            <toolkit:NavigationOutTransition.Forward>
