ANDROID Navigation view drawer menu 1 item selected

Question

I have 3 menus in my navigation view where each menu have few more items. Im having problems when i press each item in menu, i want checked item to be selected but other items non selected. Bellow is picture so that you can see what is the problem:

For selection im using item.setChecked(true); in onNavigationItemSelected(MenuItem menu). What i want is only 1 item to be selected, so when i checked one item, i want that other items are not selected.

I search on google but usually they say that i need to separate each menu into group android:checkableBehavior="single" what i done but, it still do not work:

EDIT START:

I just find solution, instead of item.setChecked(true) i write navigationView.setCheckedItem(R.id.itemId); and everything works now.

I find solution on this link:

EDIT END

Here is the code for drawer_menu.xml:

Here is the code for navigation drawer menu item click events in main activity:

     navigationView = (NavigationView) findViewById(R.id.navigation_view);

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

                switch (item.getItemId()) {
                    case R.id.dog:
                        homeFragment.sortiranje("Domestic", tagonja);
                        item.setChecked(true);
                        drawerLayout.closeDrawers();
