SearchView duplicates the icon

I have a problem, I do not even know where to look, the fact is that every time I open this TabLayout or this fragment, I do not know where the error is, I add a magnifying glass to the toobar, how can I Fix?

public class Tab_Ïnicio extends Fragment {
    private AppBarLayout appBar;
    private TabLayout pestanas;
    private ViewPager viewPager;

    public Tab_Ïnicio() {
    }

    @override

                             Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.fragmento_paginado, container, false);

        if (savedInstanceState == null) {
            insertarTabs(container);

            // Setear adaptador al viewpager.
viewPager = (ViewPager) view.findViewById(R.id.pager);
            poblarViewPager(viewPager);
            pestanas.setupWithViewPager(viewPager);


            pestanas.setTabGravity(TabLayout.GRAVITY_CENTER);
            pestanas.setTabMode(TabLayout.MODE_FIXED);
            //pestanas.setTabMode(TabLayout.MODE_SCROLLABLE);
}

        return view;
    }

    public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
        inflater.inflate(R.menu.menu_main, menu);
        super.onDestroyView();
    }


    private void insertarTabs(ViewGroup container) {
        View padre = (View) container.getParent();
        appBar = (AppBarLayout) padre.findViewById(R.id.appbar);
        pestanas = new TabLayout(getActivity());
        pestanas.setTabTextColors(Color.parseColor("#FFFFFF"), Color.parseColor("#FFFFFF"));
        appBar.addView(pestanas);
    }

    private void poblarViewPager(ViewPager viewPager) {
        AdaptadorSecciones adapter = new AdaptadorSecciones(getFragmentManager());

        adapter.addFragment(new FragGridCampos(), ("Todos"));
        adapter.addFragment(new FragGridComentarios(), ("Comentarios"));
        viewPager.setAdapter(adapter);
    }
