本文採用一个Demo来展示Android中ExpandableListView控件的使用，如怎样在组/子ListView中绑定数据源。直接上代码例如以下：

程序结构图：

layout文件夹下的 main.xml 文件源代码例如以下：

包 com.andyidea.demo中ContactsActivity.java源代码例如以下：

package com.andyidea.demo;import java.util.ArrayList;import java.util.List;import android.app.ExpandableListActivity;import android.os.Bundle;import android.view.Gravity;import android.view.View;import android.view.ViewGroup;import android.view.Window;import android.widget.AbsListView;import android.widget.BaseExpandableListAdapter;import android.widget.TextView;public class ContactsActivity extends ExpandableListActivity {		List
     
       group;           //组列表	List
      
       
        > child;     //子列表	ContactsInfoAdapter adapter;  //数据适配器	    /** Called when the activity is first created. */    @Override    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        requestWindowFeature(Window.FEATURE_NO_TITLE);  //设置为无标题        setContentView(R.layout.main);        getExpandableListView().setBackgroundResource(R.drawable.default_bg);                initializeData();        getExpandableListView().setAdapter(new ContactsInfoAdapter());        getExpandableListView().setCacheColorHint(0);  //设置拖动列表的时候防止出现黑色背景    }        /**     * 初始化组、子列表数据     */    private void initializeData(){    	group = new ArrayList
        
         ();    	child = new ArrayList
         
          
           >(); addInfo("Andy",new String[]{"male","138123***","GuangZhou"}); addInfo("Fairy",new String[]{"female","138123***","GuangZhou"}); addInfo("Jerry",new String[]{"male","138123***","ShenZhen"}); addInfo("Tom",new String[]{"female","138123***","ShangHai"}); addInfo("Bill",new String[]{"male","138231***","ZhanJiang"}); } /** * 模拟给组、子列表加入数据 * @param g-group * @param c-child */ private void addInfo(String g,String[] c){ group.add(g); List
           
             childitem = new ArrayList
            
             (); for(int i=0;i
            
           
          
         
        
       
      
     

最后，程序执行后截图例如以下：
