Answer 1

Take a look at this project https://github.com/Shereef/ViewPagerPlusExpandableList (import it in eclipse indigo, or take a look at the code online), this was my answer to my question: How to implement an ExpandableList in a ViewPager in Android?

Should be very helpful to your question if it doesn't fully solve it.

Answer 2

Here is one implementation of a ViewPager with different ListView's as pages.

MainActivity.java

public class MainActivity extends Activity {

    /** Called when the activity is first created. */

 private Context mContext;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        mContext = this;
        setContentView(R.layout.main);
        ListView listview1 = new ListView(mContext);
        ListView listview2 = new ListView(mContext);
        ListView listview3 = new ListView(mContext);

        Vector<View> pages = new Vector<View>();

        pages.add(listview1);
        pages.add(listview2);
        pages.add(listview3);

        ViewPager vp = (ViewPager) findViewById(R.id.viewpager);
        CustomPagerAdapter adapter = new CustomPagerAdapter(mContext,pages);
        vp.setAdapter(adapter);

        listview1.setAdapter(new ArrayAdapter<String>(mContext, android.R.layout.simple_list_item_1,new String[]{"A1","B1","C1","D1"}));
        listview2.setAdapter(new ArrayAdapter<String>(mContext, android.R.layout.simple_list_item_1,new String[]{"A2","B2","C2","D2"}));
        listview3.setAdapter(new ArrayAdapter<String>(mContext, android.R.layout.simple_list_item_1,new String[]{"A3","B3","C3","D3"}));

    }
}

CustomPagerAdapter.java

public class CustomPagerAdapter extends PagerAdapter {

 private Context mContext;
 private Vector<View> pages;

 public CustomPagerAdapter(Context context, Vector&lt;View&gt; pages) {
  this.mContext=context;
  this.pages=pages;
 }

 @Override
 public Object instantiateItem(ViewGroup container, int position) {
  View page = pages.get(position);
  container.addView(page);
  return page;
 }

 @Override
 public int getCount() {
  return pages.size();
 }

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

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

}
