No, you can't.
On the Android platform, you define an Activity's UI using a hierarchy
of View and ViewGroup nodes.
Home & your activity are different activity, they have their own view
hierarchy.
Key events are always delivered to the View currently in focus. They
are dispatched starting from the top of the View hierarchy, and then
down, until they reach the appropriate destination.
But not the view of other activity.
