@Override
public void onPrepareOptionsMenu(Menu menu) {
    super.onPrepareOptionsMenu(menu);

    MenuItem item3  = menu.findItem(R.id.ID OF MENU);
    item3.setVisible(false);
}

Two questions: 1.) Are you referring to the method in the activity or the fragment? 2.) This works well with a few items but if I have many items i will have to set them false and then make them visible again when i need them.. – AndroidEnthusiast Dec 02 '13 at 15:57
@AndroidEnthusiast i'm referring it in fragment then make group of menu items and toggle visibility of group. – Nitin Misra Dec 02 '13 at 16:36

If you wish to hide ALL menu items, just do:

@Override
public void onAttach(final Activity activity) {

    super.onAttach(activity);

    setHasOptionsMenu(true);
}

@Override
public void onPrepareOptionsMenu(final Menu menu) {

    super.onPrepareOptionsMenu(menu);

    menu.clear();//This removes all menu items (no need to know the id of each of them)
}

+1 for that! Actually, just putting `return false;` as the only statement within `onPrepareOptionsMenu()` also removes the whole menu. – 1111161171159459134 Sep 02 '15 at 20:10
@1111161171159459134 how do you return false in a 'void' function? – zdd Apr 07 '17 at 16:39
@zdd I don't know how; the fact is that `return false;` does remove the whole menu! Did you try it? – 1111161171159459134 Apr 08 '17 at 17:41
@1111161171159459134, we have some gap, this function return boolean in Activity but return void in Fragment, that's the difference. – zdd Apr 12 '17 at 15:49

What i understand with your post is::

You have 3 fragments
You have 3 different set of actionbar buttons for 3 fragments

My preferred approach::You can also find the menu items which you dont want to display in your current fragment and set their visibility

MenuItem item = menu.findItem(<id>);
item.setVisible(<true/false>);

ex::

MenuItem item1 = menu.findItem(R.id.searchID);
item1.setVisible(false);
