    public void setContentView(int layoutResID)
    {
        DrawerLayout fullView = (DrawerLayout) getLayoutInflater().inflate(R.layout.activity_base, null);
        FrameLayout activityContainer = (FrameLayout) fullView.findViewById(R.id.activity_content);
        getLayoutInflater().inflate(layoutResID, activityContainer, true);
        super.setContentView(fullView);
        Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);

                public void onDrawerClosed(View view)

                    //drawerOpened = true;
                }
            };
            mDrawerToggle.setDrawerIndicatorEnabled(true);
            drawerLayout.setDrawerListener(mDrawerToggle);
            mDrawerToggle.syncState();
