在玩游戏时停止通知栏弹出 [英] Stopping notification bar to popup during game play

问题描述

上下文: 我正在使用XNA 4.0框架开发Windows Phone游戏.在游戏过程中，如果用户不小心拖动了屏幕顶部，则通知中心将被向下拖动.

Context: I am working on a windows phone game using XNA 4.0 framework. During the gameplay, if the user accidentally drags the top of screen, notification center gets dragged down.

我看到很少有应用程序可以覆盖此行为，而不是弹出通知中心，而是在顶部显示了一个小提示，如下面的屏幕快照所示.

I have seen few apps where this behaviour is overridden and instead of notification center popping up, a small cue is shown at the top as shown in the screenshot below.

问题: 当用户在游戏过程中不小心拖动屏幕顶部时，阻止通知中心出现的API是什么?

Question: What is the API that stops notification center to come up when user accidentally drags the top of screen during gameplay?

我想要实现的屏幕截图:

推荐答案

要隐藏通知栏，您需要做两件事:

To hide the notification bar, you need to do two things:

1. 将您的应用设置为全屏显示
2. 将系统托盘隐藏在页面中

您可以通过更改RootFrame的FullScreen属性将应用程序设置为全屏显示.例如，可以在App构造函数的App.xaml.cs文件中完成此操作:

You can set your application as full screen by changing the FullScreen property of your RootFrame. This can be done for instance in the App constructor, in the App.xaml.cs file:

public App()
{
    // Global handler for uncaught exceptions.
    UnhandledException += Application_UnhandledException;

    // Standard XAML initialization
    InitializeComponent();

    // Phone-specific initialization
    InitializePhoneApplication();

    // Hide the notification bar
    // Note: this must be done *after* InitializePhoneApplication
    RootFrame.FullScreen = true;

    // Language display initialization
    InitializeLanguage();
}

然后，还必须通过设置SystemTray.IsVisible属性来隐藏页面上的系统托盘.这可以在C#代码或XAML中完成:

Then, you also have to hide the system tray on your pages, by setting the SystemTray.IsVisible property. This can be done either in the C# code or in the XAML:

<phone:PhoneApplicationPage
    x:Class="SL8._1.MainPage"
    xmlns:shell="clr-namespace:Microsoft.Phone.Shell;assembly=Microsoft.Phone"
    shell:SystemTray.IsVisible="False">
