推荐答案

您不能拦截键和做到这一点，除非你有机会到Android源$ C ​​$ c和可以改变它。从应用程序的角度来看，你可以，除非你有源要么不能做到这一点。请记住，这是在Android中皱起了眉头。

You cannot intercept the key and do this unless you have access to the android source code and can change it. From an app's perspective, you can't do this unless you have the source either. Keep in mind that this is Frowned upon in android.

所以，你必须提供的唯一事情是onUserLeaveHint（），这是从活动的方法。但你还是不能从回家阻止用户。

So the only thing you have available is onUserLeaveHint() which is a method from an Activity. But you still CANNOT stop a user from going home.

下面是证明你不能直接做

Here is proof that you cannot do it directly

    public static final int KEYCODE_HOME

    Since: API Level 1
    Key code constant: Home key. This key is handled by the 
framework and is never delivered to applications.
    Constant Value: 3 (0x00000003)
