Answer 1

I have viewpager with fragments and I need set custom action bar for every fragment in pager In desired page I have navigation list, fragment fires onNavigationItemSelected automatically when I swipe pages, want to avoid this behavior and run tasks only if I selected nav item manually.

public class MyFragment extends Fragment implements ActionBar.OnNavigationListener {

    private boolead fireReady = false;

     @Override
    public void setUserVisibleHint(boolean isVisibleToUser) {
        super.setUserVisibleHint(isVisibleToUser);

        // every time make it false, this method invoked on swipe action
        fireReady = false; 

        if (isVisibleToUser) {
            // setup actionbar, you also can setup action bar in activity
            String[] array = getActivity().getResources().getStringArray(R.array.users_order);
            ArrayAdapter adapter = new ArrayAdapter(getActivity(), android.R.layout.simple_spinner_item, array);
            adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);

            getActivity().getActionBar().setNavigationMode(ActionBar.NAVIGATION_MODE_LIST);
            getActivity().getActionBar().setListNavigationCallbacks(adapter, this);
        }

    }

     @Override
    public boolean onNavigationItemSelected(int itemPosition, long itemId) {

        if (fireReady) {
            // task fire only when you directly press navigation item
            UsersTask task = new UsersTask(getActivity());
            task.setTaskListener(this);
            task.execute(usersUrls[itemPosition]);
        } else {
            // make it true first time when page displayed
            fireReady = true;
        }
        return false;
    }

}

}
