How to hide buttons on actionbar of certain fragments,where fragments are part of navigation drawer

Question

I have a MainActivity on that I have a navigation drawer,Lists of navigation drawers are fragments. I want to have refresh button on one of my fragment,to add refresh button on action bar i added following code in my MainActivity

  @Override
public boolean onCreateOptionsMenu(Menu menu) {
    MenuInflater inflater = getMenuInflater();
    inflater.inflate(R.menu.activity_main_actions, menu);

    return super.onCreateOptionsMenu(menu);
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    // toggle nav drawer on selecting action bar app icon/title
    if (mDrawerToggle.onOptionsItemSelected(item)) {
        return true;
    }
    if (item.getItemId() == R.id.action_settings) {
        return true;
    } else if(item.getItemId() == R.id.action_refresh) {

        if(haveNetworkConnection(getApplicationContext()))
        {
            LoadAllProducts task = new LoadAllProducts(ListDepartmentSemesterActivity.this);
            task.execute();
        }else{
            Toast.makeText(getApplicationContext(), "No Internet Connection", Toast.LENGTH_LONG).show();
        }

        return true;
    }else {
        return super.onOptionsItemSelected(item);
    }
}

But the thing is on every fragment refresh button is visible and from any fragments i can refresh products,how to hide it on other fragments??? Navigation drawer MainActivity and Fragments share same action bar???

Define onOptionsItemSelected(MenuItem item) in fragment and add your refresh button to it. And insert this in your fragment:

@Override
public void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);

    setHasOptionsMenu(true);
    setRetainInstance(true);


}

if you want handle menu button in each fragment try this code

@Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {

        View rootView = inflater.inflate(R.layout.simple_calendar_view,
                container, false);
        // you code here 

        setHasOptionsMenu(true);
        return rootView;
    }

inside same fragment you want handle its menu item clicks

@Override
    public boolean onOptionsItemSelected(MenuItem item) {
        switch (item.getItemId()) {
        case R.id.action_refresh:
             // you Custom code here 
             // Example i make method called Refresh_event
            Refresh_event();
            break;

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

if you need hide some menu item when you open slide menu navigation

in you activity that host fragments

           public void onDrawerClosed(View view) {  


                // calling onPrepareOptionsMenu() to show action bar icons
                supportInvalidateOptionsMenu();
            }

            public void onDrawerOpened(View drawerView) {


                // calling onPrepareOptionsMenu() to hide action bar icons
                supportInvalidateOptionsMenu();
            }

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