how to Detect Touch event EVERYWHERE !?

Hello,

i created a View component that i use in every page of my application mobile.
in this view component i want to detect every touch on the root page ( i know how to detect touch on my component by adding GestureRecognizers )

i think it's possible to handle this information because in debug mode every time i touch the screen a line on the console appear :
07-26 10:24:17.541 I/ViewRootImpl(29702): ViewRoot's Touch Event : ACTION_UP
07-26 10:24:18.149 I/ViewRootImpl(29702): ViewRoot's Touch Event : ACTION_DOWN

so if i could handle this event in my application ... but i don't know how !

Thx to help me ^^
