在按钮上的片段中隐藏菜单项，然后单击Android

Question

I have a fragment where I am displaying a Menu with 2 menu items. Currently the menu items are shown as the fragment is displayed. Now, I want to hide them once a certain action takes place eg. User deletes some text. I have tried the following code but the menu items still display :

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

    @Override
    public void onPrepareOptionsMenu(Menu menu)
    {
            if (isDeleted)
            {
                status = false;
                menu.findItem(R.id.action_edit).setVisible(false);
            }
        }
    }

How can I hide and unhide the menu items inside a fragment?

Answer 1

What you've got now seems good, you're just missing invalidateOptionsMenu call:

isDeleted = true;
getActivity().invalidateOptionsMenu();
