How to get the id of Sub Menu in Navigation view

I have implemented new Navigation view in navigation drawer. Now I want to hide and show the logout menu item on several login and logout condition.

here is my menu item of navigation view 

<group android:checkableBehavior="single">

    <item
        android:id="@+id/home"
        android:checked="false"
        android:icon="@drawable/drawer_ic_home"
        android:title="@string/home_string" />

    <item
        android:id="@+id/offer_coffee"
        android:checked="false"
        android:icon="@drawable/drawer_ic_offer_coffee"
        android:title="@string/offer_coffee_string" />


    <item
        android:id="@+id/share_coffee"
        android:checked="false"
        android:icon="@drawable/drawer_ic_share_coffee"
        android:title="@string/share_coffee_string" />
    <item
        android:id="@+id/take_coffee"
        android:checked="false"
        android:icon="@drawable/drawer_ic_take_coffee"
        android:title="@string/take_coffee_string" />


    <item
        android:id="@+id/offer_status"
        android:checked="false"
        android:icon="@drawable/drawer_ic_coffee"
        android:title="@string/offer_status"
        />


    <item
        android:id="@+id/about_us"
        android:checked="false"
        android:icon="@drawable/drawer_ic_about_us"
        android:title="@string/about_us_string" />

    <item
        android:id="@+id/logout"
        android:checked="false"
        android:icon="@drawable/logout"
        android:title="@string/logout" />

</group>

I want to hide the Logout item if I am not login and if I am login then I want to show this sub menu.

I have seen several links but they all are working on group of items but in my case I have to access single sub menu item named Logout in the group .

Thanks all for helping me , I was doing exactly both same things answered above. but some how I managed to do it in different way and that is to get the tile of the menu item clicked and then comparing it , if the item title is logout , and if I am logged in (As per my case ) do what ever I want.

The whole menu is indexed from 0 to n from top to bottom. So you have two groups with 5 item each then it is from 0 to 9.

private boolean ifNotLoggedIn;
private NavigationView navigationView;

...
protected void onCreate(Bundle savedInstanceState) {

        ...

        if(ifNotLoggedIn){
            navigationView.getMenu().getItem(7).setVisible(false);
        }
    }

Edit

As @Moinkhan pointed out, we can use the findById() method as well to do the similar.

navigationView.getMenu().getItem(R.id.logout).setVisible(false);

It's simple just add the following code.

I am assuming that you are taking isUserLoggedIn boolean variable to store user login state.

navigationView = (NavigationView) findViewById(R.id.nav); Menu menu = navigationView.getMenu(); if (! isUserLoggedIn) { menu.findItem(R.id.logout).setVisible(false); }
