描述

I want to handle long click on BottomNavigationView items for making own context menu like its in Instagram when user can hold "accout" icon and choose another profile. I use this code:

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        BottomNavigationView bottomNavigationView = findViewById(R.id.bottom_navigation);
        bottomNavigationView.setOnNavigationItemSelectedListener(listener);
        bottomNavigationView.setSelectedItemId(R.id.nav_messages);

        bottomNavigationView.findViewById(R.id.nav_profile).setOnLongClickListener(new View.OnLongClickListener() {
            @Override
            public boolean onLongClick(View v) {
                Toast.makeText(getApplicationContext(), R.string.dark_mode, Toast.LENGTH_SHORT).show();
                return true;
            }
        });

        showFragment(new MessagesFragment());
    }

But it works only when I start the app and holding item. If I start clicking on items and after that try to hold item again it does not work. It seems like listener stops working after user starts communicating with BottomNavigationView. Thank you.
