mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
mDrawerList.setOnItemClickListener(new DrawerItemClickListener());
mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout,toolbar,
R.string.title_activity_main, R.string.title_activity_main) {
@Override

super.onDrawerClosed(view);
invalidateOptionsMenu(); //creates call to onPrepareOptionsMenu()
