        setContentView(R.layout.activity_main);
            drawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
                TitleNavigationAdapter adapter = new TitleNavigationAdapter(this, items);
                drawerList = (ListView) findViewById(R.id.list_slidermenu);
                drawerList.setAdapter(adapter);

                drawerList.setOnItemClickListener(this);
                drawerLayout.setDrawerShadow(R.drawable.drawer_shadow,
                        GravityCompat.START);
                // getActionBar().setHomeButtonEnabled(true);
                getActionBar().setDisplayHomeAsUpEnabled(true);

                drawerToggle = new ActionBarDrawerToggle(this, drawerLayout,
                        R.drawable.ic_drawer, R.string.desc, R.string.refresh) {
                    @Override
                    public void onDrawerClosed(View drawerView) {
                        super.onDrawerClosed(drawerView);
                        drawerToggle.syncState();
                    }

                    @Override
                    public void onDrawerOpened(View drawerView) {
                        super.onDrawerOpened(drawerView);
                        getActionBar().setTitle("Opened");
                    }

                };
                drawerLayout.setDrawerListener(drawerToggle);
            }

            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position,
                    long id) {
