Android: How to invoke programmatically onScroll event in ListView

Question

I am trying to invoke programmatically onScroll event in ListView.

Can anybody help me?

Here my code:

@RunWith(RobolectricTestRunner.class)
public class ActivityListViewTest {

    private ActivityListView activity;

    @Before
    public void setUp() throws Exception {
        activity = new ActivityListView();
    }

    @Test
    public void shouldUpdateListViewChildCountOnCreate() throws Exception{
        activity.onCreate(null);
        ListView calendarListView = (ListView)activity.findViewById(R.id.listview);

        assertTrue("CHILD COUNT IS: " + calendarListView.getChildCount(), calendarListView.getChildCount() > 0);

        // Here i want to invoke onScroll event. Then ListView must update and listView items count become to be more that 20

        assertTrue("CHILD COUNT IS: " + calendarListView.getChildCount(), calendarListView.getChildCount() > 20);
    }
}

Add the code you are using... – Nallath May 27 '11 at 12:39 — Nallath, May 27 '11 at 12:39

From the official documentation:

public void smoothScrollByOffset (int offset)

or

public void smoothScrollToPosition (int position)
