Know which menu resource is inflated

Question

Im my application I inflate different menu resources, like this:

public boolean onCreateOptionsMenu(Menu menu) {
    _menu = menu;
    if (/* CONDITION */) {
        getMenuInflater().inflate(R.menu.menu_activity_detail, _menu);
    } else {
        getMenuInflater().inflate(R.menu.menu_empty, _menu);
    }
    return true;
}

before this I save the Menu object for further reuse, like inflating a new menu under specific circumstances.

Now the question: is there any way to know which resource I've inflated at the creation of my activity, without manually saving the id of R.menu.menu_res?

In some other method I need to change the menu, but I don't want to clear and inflate the same menu everytime. NowI do `_menu.clear(); getMenuInflater().inflate(R.menu.menu_activity_detail, _menu);`, but most of the times the menu inflated is always the same. I would like to avoid this. — Luca, Jul 14 '15 at 10:02
You should not keep a reference to the menu. Why don't you use the invalidateOptionsMenu() method of your Activity? There's the supportInvalidateOptionsMenu() to handle AppCompatActivity — Mimmo Grottoli, Jul 14 '15 at 10:17
