Windows Phone 7.x Silverlight应用程序可以在HD 720p设备上伸展(删除黑条)吗? [英] Windows Phone 7.x Silverlight App stretch on HD 720p device (remove black bar)?

问题描述

我写了一个可以兼容WP 7.x和WP 8的应用程序.通过"C#Reflector"，我可以检索有关WP版本和屏幕类型(WVGA，WXGA，HD720p)的信息.但是我无法在HD 720p设备中扩展我的应用程序.我试过设置TranslateTransform 到RootFrame.RenderTransform和RootFrame的大小.但是，当应用程序的页面为横向时，布局不正确.我该怎么办???

解决方案

您不能.  您需要将您的应用升级到Windows Phone 8应用，才能在720p显示屏上使用全屏.  这是因为WP7应用程序仅适用于一个长宽比.   720p具有不同的宽高比.

I write an application can compatible both WP 7.x and WP 8. By "C# Reflector", i can retrieve information about WP version and Screen type (WVGA, WXGA, HD720p). But i can't stretch my application in HD 720p Device. I tried set TranslateTransform to RootFrame.RenderTransform and size of RootFrame. But it incorrect layout when Application's Page is Landscape. How can i do this??? 

解决方案

You can't.  You need to upgrade your app to a Windows Phone 8 app in order to use the full screen on 720p displays.  This is because WP7 apps were made for only one aspect ratio.  720p has a different aspect ratio.
