import greendroid.app.GDExpandableListActivity; 
import greendroid.widget.ActionBarItem.Type; 

import java.util.ArrayList; 
import java.util.HashMap; 
import java.util.List; 
import java.util.Map; 

import android.os.Bundle; 
import android.widget.ExpandableListAdapter; 
import android.widget.SimpleExpandableListAdapter; 

public class ExpListViewActivity extends GDExpandableListActivity { 
    private static final String NAME = "NAME"; 
    private static final String IS_EVEN = "IS_EVEN"; 

    DataBaseHelper dbHelper; 


    private ExpandableListAdapter mAdapter; 

    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     addActionBarItem(Type.Add); 
    List<Map<String, String>> groupData = new ArrayList<Map<String, String>>(); 
    List<List<Map<String, String>>> childData = new ArrayList<List<Map<String, String>>>(); 


    for (int i = 0; i < 20; i++) { 
     Map<String, String> curGroupMap = new HashMap<String, String>(); 
     groupData.add(curGroupMap); 
     curGroupMap.put(NAME, "Item " + i); 
     curGroupMap.put(IS_EVEN, (i % 2 == 0) ? "This group is even" : "This group is odd"); 

     List<Map<String, String>> children = new ArrayList<Map<String, String>>(); 
     for (int j = 0; j < 5; j++) { 
      Map<String, String> curChildMap = new HashMap<String, String>(); 
      children.add(curChildMap); 
      // curChildMap.put(NAME, "Child " + j); 
      curChildMap.put(IS_EVEN, (j % 2 == 0) ? "Hello " + j: "Good Morning "+ j); 
     } 
     childData.add(children); 
    } 

    // Set up our adapter 
    mAdapter = new SimpleExpandableListAdapter(
      this, 
      groupData, 
      android.R.layout.simple_expandable_list_item_1, 
      new String[] { NAME, IS_EVEN }, 
      new int[] { android.R.id.text1, android.R.id.text2 }, 
      childData, 
      android.R.layout.simple_expandable_list_item_2, 
      new String[] { NAME, IS_EVEN }, 
      new int[] { android.R.id.text1, android.R.id.text2 } 
      ); 
    setListAdapter(mAdapter); 

    }
