Windows应用商店应用程序-黑屏过渡了一段时间 [英] Windows Store App - Black Screen Transition for a while

问题描述

在我的应用页面之间导航时出现问题. 从页面"a"到页面"b"，我看到黑屏仅一秒钟，然后再看到页面"b".它也发生在相反的导航中. 我知道这个问题很普遍，也此处 ，但我不知道该如何解决...而且查看起来非常难看...

i have a problem while navigating between pages of my app. Going from page "a" to page "b", i see a black screen just a second before seeing the page "b". It also happens in the opposite navigation. I know this issue is quite common, also here, but i don't understand how to solve it...and it's very ugly to view...

只是一个重要信息:我已经将自定义图像设置为两个页面(a，b)的背景...正如您在代码"Assets/Page.jpg"中所看到的

just an important information: i've set a custom image as background of both the pages(a,b)...as you can see in the code "Assets/Page.jpg"

这是我的基本页面"a" XAML:

Here is my basic page "a" XAML:

推荐答案

您可以使用app.xaml中的RequestedTheme属性来更改默认主题.选项是黑暗与光明"主题.在另一选项上进行选择会同时更改文本颜色和默认过渡.

You could use RequestedTheme property in app.xaml to change the default theme. Options are Dark and Light theme. Choosing one over the other will change text color and default transitions too.
