How can I hide tabs while scrolling down a ListView then show them again if the user scrolls up?

Question

I want to make the tabs of a tabhost fade up if the user is scrolling down a listview

I have the following code but it does not work

ListView ls = (ListView) findViewById(R.id.list);
        ls.setOnScrollListener(new OnScrollListener() {
            public void onScrollStateChanged(AbsListView view, int scrollState) {

            }
            int previousVisible = 3;
            public void onScroll(AbsListView view, int firstVisibleItem,
                    int visibleItemCount, int totalItemCount) {
                if (previousVisible < firstVisibleItem) {
                    getParent().findViewById(android.R.id.tabhost)
                            .setVisibility(View.INVISIBLE);
                } else {
                    getParent().findViewById(android.R.id.tabhost)
                            .setVisibility(View.VISIBLE);
                }
                previousVisible = firstVisibleItem;
            }
        });

May be fake tab is suitable. Add fake tabhost in headerview of listview. — Trung Nguyen, Nov 01 '12 at 15:48
@Yul That would mean the user would have to scroll all the way to the top to see the tabs again — 124697, Nov 01 '12 at 17:35
So you can elaborate what you want in the question. When you want show and hide tabhost. — Trung Nguyen, Nov 02 '12 at 00:52

Lars Werkman has implemented an Android Library to implement this UI principle from Roman Nurik and Nick Butcher.

Great but this lib seems not maintained – eVoxmusic Jan 19 '15 at 04:11
I am hoping Google wil add someting to the support libraries. They use a variant of this pattern in the Google Play Market app and the G+ app. It seems to be an "emerging" UI pattern. – Glenn Bech Jan 20 '15 at 11:51
