Hide MenuItem in some Fragments

Question

I using menu drawer which has more Fragments. In some Fragments I have menu item REFRESH but in some fragments I want hide this menu item (I don't want show menu but I don't want hide ActionBar).

I try add override onCreateOptionsMenu() to Fragment where I don't want show this menu item but I can not get it to work. I try many way see commented line in code. Does any idea where is problem? And last this menu item go to hide when I activate menu drawer when is called onPrepareOptionsMenu() in MainActivity but I need do this when I'm in Fragment.

Fragment where I want hide menu item REFRESH:

 public class FindPeopleFragment extends Fragment {
    public FindPeopleFragment(){}

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        View rootView = inflater.inflate(R.layout.fragment_find_people, container, false);
        //setHasOptionsMenu(false);
        return rootView;
    }

    private Menu menu=null;
    @Override
    public void onCreateOptionsMenu(Menu menu, MenuInflater inflater)
    {
        inflater.inflate(R.menu.main, menu);
        this.menu=menu;
        menu.findItem(R.id.refresh).setVisible(false);
        getActivity().invalidateOptionsMenu();
        //setHasOptionsMenu(false);
        super.onCreateOptionsMenu(menu,inflater);
    }
}

MainActivity where is defined MENU DRAWER:

 //Slide menu item click listener
private class SlideMenuClickListener implements
        ListView.OnItemClickListener {
    @Override
    public void onItemClick(AdapterView<?> parent, View view, int position,
                            long id) {
        // display view for selected nav drawer item
        displayView(position);
    }
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.main, menu);
    return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    // toggle nav drawer on selecting action bar app icon/title
    if (mDrawerToggle.onOptionsItemSelected(item)) {
        return true;
    }
    switch (item.getItemId()) {
        case R.id.refresh:
            Toast.makeText(this, "Refreshing data...", Toast.LENGTH_SHORT).show();
            return true;
    }
    return super.onOptionsItemSelected(item);
}

 // Called when invalidateOptionsMenu() is triggered
@Override
public boolean onPrepareOptionsMenu(Menu menu) {
    // if nav drawer is opened, hide the action items
    boolean drawerOpen = mDrawerLayout.isDrawerOpen(mDrawerList);
    menu.findItem(R.id.refresh).setVisible(!drawerOpen);
    return super.onPrepareOptionsMenu(menu);
}

Answer 1

In the fragment where you want to hide the Item

@Override
public void onPrepareOptionsMenu(Menu menu) {
    MenuItem item=menu.findItem(R.id.action_search);
    if(item!=null)
       item.setVisible(false);
}

and in onCreate() of your fragment

 setHasOptionsMenu(true);

Answer 2

In the Fragment where you don't want to show any menu options, you need setHasOptionsMenu(false); in the onCreate(), like this:

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

However, the menu that is being shown that you would like to hide (REFRESH), belongs to MainActivity. That is why it is always shown. Since you want to control the menu at the Fragment level (and not show an Activity options menu), my suggestion is to delete the menu code from the Activity and implement it in your Fragment.

Activitys and Fragments can each have their own separate menus. See this link.

Answer 3

please try this

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

and put this on your fragmen's onCreate()

setHasOptionsMenu(true);
