按下“开始"按钮时如何处理事件 (Windows Phone)

问题描述

如何在按下开始"按钮(Windows Phone)时创建事件?

How can I make an event when pressed on Start button (windows Phone) ?

更新如果不可能，那么我怎么知道用户按下了开始"按钮?

UPDATEDIf it is not possible, so how can I understand that user have pressed START button ?

推荐答案

开始"和搜索"按钮本身是保留的，不会向第三方应用程序生成事件.

The Start and Search buttons themselves are reserved and do not generate events to third party applications.

话虽如此，当用户按下开始按钮时会产生两个事件:

Having said that, two events will be generated when the user pushes the start button:

1. 带有 NavigationMode 是 Forward 和 IsNavigationInitiator 是 false
2. A PhoneApplicationService.Deactivated 事件

1. A navigation event with NavigationMode being Forward and IsNavigationInitiator being false
2. A PhoneApplicationService.Deactivated event

但是，您不能使用这些事件中的任何一个取消导航，它们可能由于其他原因(例如按下搜索按钮)而发生.

However you cannot cancel the navigation using either of these events and they can occur for other reasons (like pressing the search button).
