Drawer Layout Not Displaying as Fragment

Drawer Layout Not Displaying as Fragment

The fragment is not displaying or displaying a blank screen. I wanted to
display a drawer layout in my view pager.
switch(arg0){
/** Android tab is selected */
case 0:
DrawerLayoutFragment androidFragment = new
DrawerLayoutFragment();
data.putInt("current_page", arg0+1);
androidFragment.setArguments(data);
return androidFragment;
