Recognize a menu of options from a snippet? Android

I currently have an app with 4 pages, these pages are added by fragments using the pageViewer so I can swipe in between.

I want to be able to access the Options menu (which has a default “Settings” option) from each page, so I can execute commands specifically for one page, such as the 'refresh' element that refreshes data on the current page.

Can anyone point me in the right direction? Thank!

Everyone Fragment

can declare their own menu, which will automatically merge with the current action menu.

class YourPage extends Fragment
{

    @Override
    public void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);

        // Signal that this fragment has proper actions
        setHasOptionsMenu(true);
    }

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

        // The menu will be added to the action bar
        inflater.inflate(R.menu.fragment_page_menu, menu);      
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item)
    {
        switch (item.getItemId())
        {
            case R.id.action_refresh:
            {
                // Handle the action...

                return true;
            }


            default:
                return super.onOptionsItemSelected(item);
        }       
    }   
}


Here is a complete example I did, along with a related tutorial .
