Navigation Drawer is not opening from left for method drawerLayout.openDrawer(GravityCompat.START)

Question

My HomeScreen.java

    public class HomeScreen extends AppCompatActivity implements NavigationView.OnNavigationItemSelectedListener{
            private Toolbar toolbar;
            private DrawerLayout drawerLayout;
            private NavigationView navigationView;
            private ActionBarDrawerToggle toggle;

            @Override
            protected void onCreate(Bundle savedInstanceState) {
                super.onCreate(savedInstanceState);
                setContentView(R.layout.home_screen);

                instantiateViews();
toggle = new ActionBarDrawerToggle(this,drawerLayout,toolbar,R.string.navigation_drawer_open,R.string.navigation_drawer_close);
                drawerLayout.addDrawerListener(toggle);
                toggle.syncState();
                setSupportActionBar(toolbar);
                navigationView.setNavigationItemSelectedListener(this);

        }

            public void instantiateViews(){

                    toolbar = findViewById(R.id.drawer_menu_toolbar);
                    drawerLayout = findViewById(R.id.home_screen_main_drawer_layout);
                    navigationView = findViewById(R.id.home_screen_navigation_view);

                }

        @Override
        public boolean onOptionsItemSelected(MenuItem item) {
            if (toggle.onOptionsItemSelected(item)) {
                Log.i("CLICKED","clicked");
                drawerLayout.openDrawer(GravityCompat.START);
                return true;
            }


     return super.onOptionsItemSelected(item);
            }

My Problem:

On the initial click of the ActionBarToggle the navigation drawer isn't opening. It opens only when i have swiped right initially and after that, the ActionBarToggle and the Right Swipe both open the drawer. Only when the application is restarted, the click on ActionBarToggle doesn't work. So i tried to register the click of the ActionBarToggle and in the logs, whenever i click it, it displays the following

Log.i

2019-06-21 10:00:11.860 7467-7467/com.example.gofresh I/CLICKED: clicked

2019-06-21 10:00:18.497 7467-7467/com.example.gofresh I/CLICKED: clicked

What code should i put in onOptionsItemSelected() so that the ActionBarToggle even responds to the first click?

It think you are missing visibility because you set Navigation-view. android:visibility="gone"

Handle visibility in code runtime before toggle issue
