Mainactivity

 Toolbar toolbar = findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);
    getSupportActionBar().setDisplayShowHomeEnabled(true);
    getSupportActionBar().setDisplayHomeAsUpEnabled(true);

    final DrawerLayout drawer = findViewById(R.id.drawer_layout);
    NavigationView navigationView = findViewById(R.id.nav_view);
    ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
            this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
    drawer.addDrawerListener(toggle);
    toggle.syncState();
    toggle.setDrawerIndicatorEnabled(false);
    Drawable drawable = ResourcesCompat.getDrawable(getResources(), R.drawable.ic_menu, this.getTheme());
    toggle.setHomeAsUpIndicator(drawable);
    toggle.setToolbarNavigationClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            if (drawer.isDrawerVisible(GravityCompat.START)) {
                drawer.closeDrawer(GravityCompat.START);
            } else {
                drawer.openDrawer(GravityCompat.START);
            }
        }
    });

    navigationView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() {
        @Override
        public boolean onNavigationItemSelected(@NonNull MenuItem menuItem) {

            int id = menuItem.getItemId();

            if (id == R.id.nav_whitelist) {
                Toast.makeText(mContext, "Hello world!", Toast.LENGTH_SHORT).show();
            }

            DrawerLayout drawer = findViewById(R.id.drawer_layout);
            drawer.closeDrawer(GravityCompat.START);
            return true;
        }
    });

@Override
    public void onBackPressed() {
        DrawerLayout drawer = findViewById(R.id.drawer_layout);
        if (drawer.isDrawerOpen(GravityCompat.START)) {
            drawer.closeDrawer(GravityCompat.START);
        } else {
            super.onBackPressed();
        }
    }
