Answer 1

By default the DrawerLayout is initially hidden from the view unless you put a code to open the Drawer, by the time there is a sliding event triggered.

From the Navigation Drawer example, the contain content_frame is used to dynamically display views inside the Drawer using fragments.

From the Fragment's onCreateView() you can include a button somewhere that has OnClickListener where in you put this code,

   //For me a better way in avoiding a `null pointer` in getting the DrawerLayout
   final DrawerLayout drawer = (DrawerLayout) getActivity().findViewById(R.id.drawer_layout);
   btn.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                            //Opens the Drawer
                drawer.openDrawer(Your View, Usually a ListView);
            }

                return false;
        });

You Can also use* to close the drawer.

drawer.closeDrawer(Your View, Usually a ListView);
