It will be in list header not as an item so it shouldn't be a problem.</p> <pre><code>public class CustomActivity extends ListActivity { private static int NUM_AWESOME_VIEWS = 20; private Context cxt; private CustomPageAdapter pageAdapter; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); String[] items = { "this", "is", "my", "list", "view", "data" }; this.cxt = this; ViewPager viewPager = new ViewPager(this); pageAdapter = new CustomPageAdapter(); viewPager.setAdapter(pageAdapter); viewPager.requestLayout(); getListView().addHeaderView(viewPager); setListAdapter(new ArrayAdapter&lt;String&gt;(this, android.R.layout.simple_list_item_1, items)); } private class CustomPageAdapter extends PagerAdapter{ @Override public int getCount() { return NUM_AWESOME_VIEWS; } /** * Create the page for the given position. The adapter is responsible * for adding the view to the container given here, although it only * must ensure this is done by the time it returns from * {@link #finishUpdate()}. * * @param container The containing View in which the page will be shown. * @param position The page position to be instantiated. * @return Returns an Object representing the new page. This does not * need to be a View, but can be some other container of the page. */ @Override public Object instantiateItem(View collection, int position) { TextView tv = new TextView(cxt); tv.setText("Bonjour PAUG " + position); tv.setTextColor(Color.WHITE); tv.setTextSize(20); ((ViewPager) collection).addView(tv,0); return tv; } /** * Remove a page for the given position.
