[UWP] - 显示转换，例如当View变为可见时，EntranceThemeTransition [英] [UWP] - Show transition e.g. EntranceThemeTransition when View becomes Visible

问题描述

您好，

我在页面中有一个以Visibility = Collapsed开头的视图。我想使用其中一个内置转换，例如EntranceThemeTransition在该视图变为可见时为其设置动画。这可能吗？

谢谢

解决方案

Hello bjames_dev，

No EntranceThemeTransition不符合您的要求。请在此处查看官方文档：

https： //docs.microsoft.com/en-us/windows/uwp/graphics/animations-overview

您将阅读以下内容：

" EntranceThemeTransition 表示可以应用于内容的动议首先加载页面或大部分UI。因此，内容的第一次出现可以
提供与内容更改不同的反馈。
EntranceThemeTransition 相当于
NavigationThemeTransition 使用默认参数，但可以在
之外使用 框架 。"

它仅在首次加载UI时有效。因此，如果你想使用EntranceThemeTransition，你必须删除/添加UI，这样它才会显示效果。

祝你好运，

Hello,

I have a View within a Page that begins with Visibility=Collapsed. I would like to use one of the in-built transitions e.g. EntranceThemeTransition to animate this view when it becomes visible. Is this possible?

Thanks

解决方案

Hello bjames_dev,

No EntranceThemeTransition does not meet your requirement. Please check the official doc here:

https://docs.microsoft.com/en-us/windows/uwp/graphics/animations-overview

You will read the following:

"EntranceThemeTransition represents a motion that can apply to content when a page or large section of UI is first loaded. Thus the first appearance of content can offer different feedback than a change to content does. EntranceThemeTransition is equivalent to a NavigationThemeTransition with the default parameters, but may be used outside of a Frame."

It only works when your UI is first loaded. So if you want to work with EntranceThemeTransition, you have to delete/add the UI so it will show you the effect.

Best regards,

Barry
