BottomNavigationView enable click disable check

I'm using a BottomNavigationView with 5 items, 4 Fragments and 1 Activity as in the image below

When any fragment is clicked I want it to act normally getting clicked and checked, but when the "+" item is clicked I'm opening an Activity but I don't want it to be checked, so I want it to be clickable so it can open the Activity, but I don't want to be checked, because when the user return back from the activity will see it selected even though it's the wrong selected item. How can I do this?

Here's my code:

bottomNavigationView = findViewById(R.id.bottom_nav_view);
bottomNavigationView.setOnNavigationItemSelectedListener(this);

.

@Override
public boolean onNavigationItemSelected(@NonNull MenuItem menuItem) {
    int id = menuItem.getItemId();
    Fragment fragment = null;
    switch (id) {
        case R.id.home_nav_menu:
            fragment = new HomeFragment();
            break;
        case R.id.inbox_nav_menu:
            fragment = new InboxFragment();
            break;
        case R.id.add_nav_menu:
            Intent intent = new Intent(this, AddActivity.class);
            startActivity(intent);
            return true;
        case R.id.history_nav_menu:
            fragment = new HistoryFragment();
            break;
        case R.id.profile_nav_menu:
            fragment = new ProfileFragment();
            break;
    }
    getSupportFragmentManager().beginTransaction().replace(R.id.fragment_place_holder, fragment).commit();
    return true;
}

Seeing at the source code of the listener for the bottom navigation, you just need to return false when you don't want to display item as selected. 

 /**
     * Listener for handling selection events on bottom navigation items.
     */
    public interface OnNavigationItemSelectedListener {

        /**
         * Called when an item in the bottom navigation menu is selected.
         *
         * @param item The selected item
         *
         * @return true to display the item as the selected item and false if the item should not
         *         be selected. Consider setting non-selectable items as disabled preemptively to
         *         make them appear non-interactive.
         */
        boolean onNavigationItemSelected(@NonNull MenuItem item);
    }

So you simply return false in your case R.id.add_nav_menu: and it will work.

User MenuItem#setCheckable(boolean) API in order to play with menu item's checkable state.


    MenuItem menuItem = navigation.getMenu().getItem(1);
    menuItem.setCheckable(false);

Try like this: 

@Override
public boolean onNavigationItemSelected(@NonNull MenuItem menuItem) {
int id = menuItem.getItemId();
Fragment fragment = null;
switch (id) {
    case R.id.home_nav_menu:
        fragment = new HomeFragment();
        break;
    case R.id.inbox_nav_menu:
        fragment = new InboxFragment();
        break;
    case R.id.add_nav_menu:
  menuItem.setCheckable(false);
        Intent intent = new Intent(this, AddActivity.class);
        startActivity(intent);
        return true;
    case R.id.history_nav_menu:
        fragment = new HistoryFragment();
        break;
    case R.id.profile_nav_menu:
        fragment = new ProfileFragment();
        break;
}
getSupportFragmentManager().beginTransaction().replace(R.id.fragment_place_holder, fragment).commit();
return true;
}
