问题描述

我为 UWP 平台编写了一个 YouTube 客户端，现在我卡在全屏模式下.我已经根据 MediaElement 和 .

I write an YouTube client for UWP platform and now I'm stuck on fullscreen mode. I've written own video player based on MediaElement with .

当我进入全屏时，我得到了这个

And when I go to fullscreen I get this

.

所以在这种情况下，我需要以全屏模式显示整个视频播放器控件.但我不知道我应该如何做到这一点.我已经试过了:

So in that case I need to show in fullscreen mode the whole video player control. But I don't know how exactly I supposed to do this. I've already tried this:

private async void fullscreen_Click(object sender, RoutedEventArgs e)
    {
        if (!fullScreen)
        {
            ApplicationView.GetForCurrentView().TryEnterFullScreenMode();
            mainPageBackup = (Window.Current.Content as Frame).Content as MainPage;
            (Window.Current.Content as Frame).Content = this;
        }
        else
        {
            ApplicationView.GetForCurrentView().ExitFullScreenMode();
            (Window.Current.Content as Frame).Content = mainPageBackup;
        }
    }

推荐答案

实际上有一个简单的解决方案.感谢 Alamakanambra 的评论(在问题下方).当我进入全屏模式时，我只是隐藏了我不需要的所有内容.我创建了一个事件并获得了 MainPage 和 VideoPage 订阅它.

Actually there's a one simple solution. Thanks to Alamakanambra's comment (below the question). I just hide everything that I don't need when I go to fullscreen. I've created an event and get MainPage and VideoPage subscribed to it.

public event EventHandler SetFullscreen;

private async void fullscreen_Click(object sender, RoutedEventArgs e)
{
    SetFullscreen.Invoke(this, null);
    if (!fullScreen)
    {
        ApplicationView.GetForCurrentView().TryEnterFullScreenMode();
        mainPageBackup = (Window.Current.Content as Frame).Content as MainPage;
        (Window.Current.Content as Frame).Content = this;
    }
    else
    {
        ApplicationView.GetForCurrentView().ExitFullScreenMode();
        (Window.Current.Content as Frame).Content = mainPageBackup;
    }
}
