My code:

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {
    View view = inflater.inflate(R.layout.fragment_cat, null);
    return view;
}

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

    TextView header = new TextView(getActivity());
    header.setText("Header");
    getListView().addHeaderView(header);

    // ... adding objects to the adapter ...

    ArticleAdapter adapter = new ArticleAdapter(getActivity(), android.R.layout.simple_list_item_1, android.R.id.text1, objects);
    setListAdapter(adapter);
}

I'm using pinned-section-listview library.

Thank you in advance!

Pinned-section-listview does not support list headers for now. — sergej shafarenka

you try to add header getListView().addHeaderView(header);

this causes listview to wrap adapter in one more adapter, HeaderViewListAdapter, whereas library expects it's own adapter

// get expected adapter or fail
PinnedSectionListAdapter adapter = (PinnedSectionListAdapter) view.getAdapter();

You either fix used library, or post bug to it's author, or try not to use addHeader

Thank you. How should I fix this library? Do you have any idea?

I've made some modifications to original project, now we may add header to listview, but it lost all of its magnificient properties. Sections do not stick to listview's top anymore. If I get any luck with it, I'll let you know. meantime, one more question- do you really need a header? It'll scroll with content. Consider addding simple textview on top of the listview.

First of all - Thank you very much. I need to put something in the top of the screen, and when you scroll down - it will stay at top (I mean, you won't see it after you scroll down).

You don't need a header then, you need textview above your list view
