Answer 1

Try this:

 private int selectedItem = 0; 

  private void setSelectedItem(MenuItem menuItem, int position) {

          mNavigationView.getMenu().getItem(selectedItem).setChecked(false);
          mNavigationView.getMenu().getItem(position).setChecked(true);

          if (menuItem.getGroupId() == R.id.group_2) {
                    mNavigationView.getMenu().setGroupCheckable(R.id.group_1, false, true);
                    mNavigationView.getMenu().setGroupCheckable(R.id.group_2, true, true);
                } else {
                    mNavigationView.getMenu().setGroupCheckable(R.id.group_1, true, true);
                    mNavigationView.getMenu().setGroupCheckable(R.id.group_2, false, true);
                }
                //Update highlighted item in the navigation menu
                menuItem.setChecked(true);
                selectedItem = position;
    }
