On Clicking Hamburger Icon Navigation Drawer Not Opening

The navigationDrawer is not opening on clicking hamburger icon,I have used onOptionsItemSelected but it's of no use: public class CardDashBoard extends Fragment implements View.OnC

Solution 1:

Try this code its working for me

ActionBarDrawerToggle  actionBarDrawerToggle = newActionBarDrawerToggle(this, drawerLayout, toolbar, R.string.app_name, R.string.app_name) {
        @OverridepublicvoidonDrawerOpened(View drawerView) {
            super.onDrawerOpened(drawerView);

        }

        @OverridepublicvoidonDrawerClosed(View drawerView) {
            super.onDrawerClosed(drawerView);
        }
    };

    drawerLayout.addDrawerListener(actionBarDrawerToggle);

Solution 2:

Try this

ActionBarDrawerToggle drawerToggle = newActionBarDrawerToggle(this, drawerLayout, toolbar, R.string.open
                , R.string.close) {
            @OverridepublicvoidonDrawerOpened(View drawerView) {
                super.onDrawerOpened(drawerView);
            }

            @OverridepublicvoidonDrawerClosed(View drawerView) {
                super.onDrawerClosed(drawerView);
            }
        };
