It is hard to work through all that code you posted (most of which has not to do with your question), but as far as I can tell you have not even set up a ViewPager from your code or it is hidden in some XML file that you didn't post.

What you need to do is create a ViewPager instance. For example in your fragment's XML layout file, like:

<android.support.v4.view.ViewPager
    android:id="@+id/pager" 
    android:layout_width="fill_parent"
    android:layout_height="0dp" 
    android:layout_weight="1" />

Now, in your Fragment you create an adapter that specifies the pages that you want (similarly to how a ListAdapter specifies items to a ListView). For that, create a class (you can do that inline in the Fragment code) that inherits from PagerAdapter. For example, something like:

private class MyPagerAdapter extends PagerAdapter implements TitleProvider {

    private ListView pagerListView1;
    private ListView pagerListView2;

    public MyPagerAdapter() {
        LayoutInflater inflater = getActivity().getLayoutInflater();
        pagerListView1 = (ListView) inflater.inflate(R.layout.fragment_pagerlist, null);
        pagerListView2 = (ListView) inflater.inflate(R.layout.fragment_pagerlist, null);
    }

    @Override
    public int getCount() {
        return 2;
    }

    @Override
    public Object instantiateItem(View container, int position) {
        switch (position) {
        case 0:
            ((ViewPager) container).addView(pagerListView1, 0);
            return pagerListView1;
        case 1:
            ((ViewPager) container).addView(pagerListView2, 0);
            return pagerListView2;
        }
        return null;
    }

    @Override
    public void destroyItem(View container, int position, Object object) {
        ((ViewPager) container).removeView((View) object);
    }

    @Override
    public boolean isViewFromObject(View view, Object object) {
        return view == (View) object;
    }

    @Override
    public void finishUpdate(View container) {
    }

    @Override
    public Parcelable saveState() {
        return null;
    }

    @Override
    public void startUpdate(View container) {
    }

    @Override
    public void restoreState(Parcelable state, ClassLoader loader) {
    }

}

Note that I hard-coded 2 pages/lists in this pager. You can fill those as you would with any other ListView. The layout of the pages is just a simple ListView that is inflated from the fragment_pagerlist XML file, which looks something like:

<?xml version="1.0" encoding="utf-8"?>
<ListView xmlns:android="http://schemas.android.com/apk/res/android" 
    android:id="@+id/list"
    android:layout_height="match_parent"
    android:layout_width="match_parent"
    android:cacheColorHint="@color/BackgroundLight" />

Finally, you bind the ViewPager's adapter somewhere in your onActivityCreated method:

@Override
public void onActivityCreated(Bundle savedInstanceState) {
    super.onActivityCreated(savedInstanceState);

    ViewPager pager = (ViewPager) getView().findViewById(R.id.pager);
    pager.setAdapter(new MyPagerAdapter());
}

Note that this does not yet give you a ViewPagerIndicator. Check Jake Wharton's excellent library for that.

If you want the code to a fully implemented and working version, with multiple lists (and other views) in a ViewPager and a ViewPagerIndicator, take a look at the open source RateBeer for Android project; specifically http://code.google.com/p/ratebeerforandroid/source/browse/RateBeerForAndroid/src/com/ratebeer/android/gui/fragments/SearchFragment.java#486 for a real-world PagerAdapter.
