Android View Pager set Page within Fragment

I want to build a ViewPager with 2 Pages. On the first page you can choose a category. When a List item is selected the screen swipes to the second page and you can choose some subcategories.

I implemented the clicklistener and so on. But I have no idea how to set the current page from within a fragment. Is it even possible? Or do you have another solution for me? Hope you understand what I want to achieve.

use ((ActivityName)getActivity()).getViewPager().setCurrentItem(position);

note: getViewPager() should return the viewpager instance

Ok, found a solution for my own. Thanks to Sayem for the hint.

I passed the ID of the ViewPager via bundle to my first fragment. in my fragment i could use then this simple code:

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

    viewPagerId = getArguments().getInt("viewPagerId");
    View rootView = (View) inflater.inflate(R.layout.fragment_cat, container, false);
    populateListView(rootView);

    viewPager = (ViewPager) getActivity().findViewById(viewPagerId);

    return rootView;
}

and to switch pages then simply this:

viewPager.setCurrentItem(position);

Thanks for the help
