淡入/淡出Windows Store应用程序中的TextBlock [XAML / C＃] [英] Fade in/out a TextBlock in a Windows Store Application [XAML/C#]

问题描述

有人可以解释一下我在Windows Store应用程序中加载表单时如何在文本块中添加淡入和淡出动画吗？
我尝试了WPF方法，但是没有用...
谢谢：）

can someone explain me how can I add a fade in and a fade out animation to a textblock when I load a form in a Windows Store application? I tried the WPF method but it didn't work... Thank you :)

推荐答案

不确定这是否是您要查找的内容（或什么 WPF方法不起作用），但是具有以下资源：

Not sure if this is what you're looking for (or what "WPF method" didn't work), but with this resource:

<Page.Resources>
    <Storyboard x:Name="Storyboard1">
        <DoubleAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.Opacity)" Storyboard.TargetName="textBlock">
            <EasingDoubleKeyFrame KeyTime="0" Value="0"/>
            <EasingDoubleKeyFrame KeyTime="0:0:4" Value="1"/>
        </DoubleAnimationUsingKeyFrames>
    </Storyboard>
</Page.Resources>

淡入效果（在这里称为textBlock的特定实例。）显然，您可以根据自己的喜好调整持续时间和缓动功能-并可以泛化以便在各种控件中使用。

invoked from OnNavigatedTo you'll get a fade-in effect (here on a specific instance called textBlock.) Obviously, you can adjust the duration and easing function to your liking - and perhaps generalize for use across various controls.

var f = this.Resources["Storyboard1"] as Storyboard;
if (f != null) f.Begin();
