推荐答案

邮政ICS即安卓4+，在为homeButton的首要已被删除出于安全原因，以使在案件中的应用原来是一个用户出口恶意软件。

Post ICS i.e. Android 4+, the overriding of the HomeButton has been removed for security reasons, to enable the user exit in case the application turns out to be a malware.

另外，它并不是一个非常好的做法，不能让用户导航离开该应用程序。但是，因为你是一个锁屏应用程序，你可以做的就是申报活动为启动，这样，当为homeButton为pressed将只需重新启动您的应用程序，并保持有自己（用户会发现只是轻微的闪烁在屏幕）。

Plus, it is not a really good practice to not let the user navigate away from the application. But, since you are making a lock screen application, what you can do is declare the activity as a Launcher , so that when the HomeButton is pressed it will simply restart your application and remain there itself (the users would notice nothing but a slight flicker in the screen).
