onSwipe Event is not Triggered inside a ViewPager

onSwipe Event is not Triggered inside a ViewPager

I have a ViewPager, the first page(fragment) of it has a DrawerLayout that
implements a SimpleOnGestureListener that listens to onSwipe event. The
purpose of the onSwipe event inside the DrawerLayout(fragment) is to
listen if the user swipes to left and right which triggers the opening and
closing of the drawer.
The problem is by the time, I swipe to left or right the ViewPager's page
changes instead of triggering the opening and closing of the Drawer.
Is there a way to disable temporarily the swiping of the ViewPager, while
its current view is on DrawerLayout so that it can listen to the left and
right event?
If the Drawer is opened and If I swipe the screen to the right then that's
the time the page changes. I've been struggling with this for a couple of
days now.
