Description
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:
```java
@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.

Research direction
Start by reproducing the shown BottomNavigationView setup, selecting several items, and then long-pressing the profile item. Inspect the BottomNavigationView item handling to determine why the long-click listener stops responding; done means long-click handling still works after navigation between items.
