title: sliding drawer appear in all activities
body: <p>I am developing an application that contains many activities 
  and i created my own menu (i don't want to use the built in menu button) with the Sliding Drawer 
  as the sliding drawer is at the bottom of the screen and contains my menu buttons </p>
  
  <p>what i need is to make that sliding drawer to appear in all my activities </p>
  
  <p>i tried to create an activity and set it's content view to the xml file that includes the drawer and then extends that activity in all other activities but this solution doesn't work </p>
  
  <p>so any suggestions ?</p>
