inflate myAdapter to myViewPager after clicking a list from the NavigationDrawer

inflate myAdapter to myViewPager after clicking a list from the
NavigationDrawer

I am trying to inflate my Views from myAdapter after clicking an item list
from my NavigationDrawer but after clicking the item from the Navigation
drawer, only my ViewPager is being displayed. It does not inflate the
Views I initialized from myAdapater even though I called setAdapater. Did
I miss something here? I followed the NavigationDrawer tutorial from
developer.android site
