Answer 1

In the menu.xml you should add all the menu items. Then you can hide items that you don't want to see in the initial loading.

Add setHasOptionsMenu(true) in the onCreate() method to invoke the menu items in your Fragment class.

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

You don't need to override onCreateOptionsMenu in your Fragment class again. Menu items can be changed (Add/remoev) by overriding onPrepareOptionsMenumethod available in Fragment.

@Override
public void onPrepareOptionsMenu(Menu menu) {
    menu.findItem(R.id.action_newItem).setVisible(true);
    super.onPrepareOptionsMenu(menu);

}
