    I saw @arsent solution and gave it a try, and it will indeed do what you want, which is to unselect all the items... but, I was having an issue in the following scenario:

    1. Select menu item 1 (using NavigationView#setCheckedItem)
    2. Unselect all the items as per @arsent's solution
    3. Select menu item 1 again (using NavigationView#setCheckedItem)

    In this scenario, item 1 will not be marked as checked. That's because internally the navigation view keeps track of the previously selected item set in step 1, which doesn't change in step 2, and it just skips step 3 because the previously selected item is the same as the one we're selecting now.

    My suggestion (and an alternative solution) to avoid this is just having a dummy invisible item and use NavigationView#setCheckedItem to select that item whenever you want to unselect all, like so

    
    

    To unselect all just do

    mNavigationView.setCheckedItem(R.id.menu_none);
