Use Cicerone library for handling navigation easily.

@Override
public boolean onNavigationItemSelected(@NonNull MenuItem menuItem) {
    switch (menuItem.getItemId()) {
        case R.id.save: {
            router.replaceScreen("your fragment1");
            menuItem.setChecked(true);
            break;
        }
        case R.id.search_lessons: {
            router.replaceScreen("your fragment2");
            menuItem.setChecked(true);
            break;
        }
        case R.id.profile_student: {
            router.replaceScreen("your fragment3");
            menuItem.setChecked(true);
            break;
        }

    }
    return false;
}
