OnCreateOptionsMenu is not called during fragment transaction

Question

I have a fragment that contains a search menu in the toolbar. when user first time click on navigation item, Fragment is added in activity which uses add method of FragmentManager and then it will be show, hide or remove from fragment container according to the logic.

My problem is when the first time I click on navigation item search menu is displayed in the toolbar but afterwards when I come back to this fragment, sometimes there will be blank toolbar without search menu. How can I solve this?

Here is the main part code of fragment:

 @Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    // Inflate the layout for this fragment
    View view = inflater.inflate(R.layout.fragment_search, container, false);

    searchFragmentInstance = this;
    filterManager = new FilterManager();

    //set toolbar
    Toolbar toolbar = view.findViewById(R.id.toolbar_search);
    ((AppCompatActivity)getActivity()).setSupportActionBar(toolbar);

    //other code...

    return view;
    }

Display search menu in toolbar using this:

@Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {

    super.onPrepareOptionsMenu(menu);
    inflater.inflate(R.menu.search, menu);
    MenuItem item = menu.findItem(R.id.action_search);

    SearchManager searchManager = (SearchManager) getContext().getSystemService(Context.SEARCH_SERVICE);

    SearchView searchView = (SearchView) item.getActionView();
    searchView.setSearchableInfo(searchManager.getSearchableInfo(getActivity().getComponentName()));
    searchView.setBackgroundColor(getResources().getColor(R.color.colorPrimaryDark));

  //other code...
}

your method onCreate (in fragment) include this " setHasOptionsMenu(true) "? — droidbaza, Apr 05 '20 at 11:30

I solved this problem by using adding this code:

//this method is called when the hidden state of the fragment is changed
//so when fragment is beign displayed using show method of fragment transaction
//this will be called

@Override
public void onHiddenChanged(boolean hidden) {
    super.onHiddenChanged(hidden);

    if(!hidden){
        //when fragment is not hidden anymore
        //convert the toolbar into actionbar
        Toolbar toolbar=(Toolbar)(((AppCompatActivity)getActivity()).findViewById(R.id.toolbar_search));
        ((AppCompatActivity)getActivity()).setSupportActionBar(toolbar);

    }
}
