一个令人无比蛋疼的线程里更新ListView的问题

弄了好几天了，想实现一个功能:显示一个ListView，在Activity的Create方法中开启一个新的线程，在线程里通过循环为一个自定义的ArrayAdapter类的add(使用父类的方法)方法增加数据，ListView已经使用setAdapter方法与自定义的ArrayAdapter绑定，希望在线程里为ArrayAdapter增加数据的同时，显示的ListView能同步显示出增加的数据，可是这么做后，会报Only the original thread that created a view hierarchy can touch its views的错误，并出现Force Close

最终希望达到的效果就是，ListView随着线程里ArrayAdapter数据项的逐步增加(故意增加延迟放慢循环)，ListView一条一条的显示数据，并不影响主界面的其他操作。

我想可能是我的思路有问题，希望能熟悉Android开发的朋友们能帮帮我，谢谢了。

另外这个代码的ListView只能显示出ArrayAdapter的前10条数据的重复组合，虽然数据的总数貌似是对的，但是ListView的显示的是ArrayAdapter的前10条数据的重复随机组合，为什么会出现这种情况呢？

再次感谢各位了！谢谢！

贴出全部代码:

主Activity代码:

ListTest.java:

public class ListTest extends Activity {

	

    private ListView lv;

	

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

    @Override

    public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.main);

        lv = (ListView)findViewById(R.id.list);

      

        

        //创建新线程用来显示列表

		HandlerThread handlerThread = new HandlerThread("hthread_readcontact");

		handlerThread.start(); //异步启动线程

		//创建Handler

		MyHandler myHandler = new MyHandler(handlerThread.getLooper());

		//创建消息对象

		Message msg = myHandler.obtainMessage();

		

		//取出消息并执行

		msg.sendToTarget();

		

    }

	

	//循环增加100个列表项

	protected void AddListItem(){

		List<PeopleInfo> myList = new ArrayList<PeopleInfo>();

		MyAdapter ca = new MyAdapter(ListTest.this,myList);

		//ca.setNotifyOnChange(true);

		lv.setAdapter(ca);

		

		for(int i=1;i<=100;i++){

			

			//增加记录

			PeopleInfo pe = new PeopleInfo();

			pe.setPeoleName("Fucker"+Integer.toString(i));

			pe.setPeopleNum(Integer.toString(i));

			System.out.println("i:"+Integer.toString(i));

			System.out.println("PeopleInfo-->Name:"+pe.peopleName);

			System.out.println("PeopleInfo-->Num :"+pe.peopleNum);

			ca.add(pe);

			

			SystemClock.sleep(50L); //为了看到效果，故意增加一个延迟

		}

		ca.notifyDataSetChanged();

	}

	

	class MyHandler extends Handler{

			

			public MyHandler(){

				

			}

			

			public MyHandler(Looper looper){

				super(looper);

			}

	

			@Override

			public void handleMessage(Message msg) {



				AddListItem();

				System.out.println("Thread is runed!");

			}

	}

	

 

}

其他类代码:

MyAdapter.java:

public class MyAdapter extends ArrayAdapter<PeopleInfo> {



	private LayoutInflater inflater;

	List<PeopleInfo> itemList;

	private static final int mResource = R.layout.contact_list; //xml布局文件



	public MyAdapter(Context context,List<PeopleInfo> objects) {

		super(context, mResource, objects);

		// TODO Auto-generated constructor stub

		inflater = LayoutInflater.from(context);

		itemList = objects;

	}

	

	@Override

	public void add(PeopleInfo object) {

		// TODO Auto-generated method stub

		super.add(object);

		//itemList.add(object);

	}



	@Override

	public void setNotifyOnChange(boolean notifyOnChange) {

		// TODO Auto-generated method stub

		super.setNotifyOnChange(notifyOnChange);

	}



	@Override

	public Filter getFilter() {

		// TODO Auto-generated method stub

		return super.getFilter();

	}



	@Override

	public View getView(int position, View convertView, ViewGroup parent) {

		// TODO Auto-generated method stub

		ViewHolder holder;

		holder = new ViewHolder();

		

		if(convertView == null){

		

			convertView = inflater.inflate(R.layout.contact_list, null);

			//convertView = inflater.inflate(R.layout.listitem, null);

			

			holder.PhoneName = (TextView)convertView.findViewById(R.id.mname);

			holder.PhoneNum = (TextView)convertView.findViewById(R.id.msisdn);

			

			convertView.setTag(holder);

			holder.PhoneName.setText(itemList.get(position).getPeopleName());

			holder.PhoneNum.setText(itemList.get(position).getPeopleNum());

			

		}

		

		return convertView;

	}

	

	class ViewHolder{

		TextView PhoneName;

		TextView PhoneNum;

	}

}

PeopleInfo.java:

public class PeopleInfo implements Serializable {

	public String peopleName;

	public String peopleNum;

	

	public String getPeopleName(){

		return peopleName;

	}

	

	public void setPeoleName(String peopleName){

		this.peopleName=peopleName;

	}

	

	public String getPeopleNum(){

		return peopleNum;

	}

	

	public void setPeopleNum(String peopleNum){

		this.peopleNum = peopleNum;

	}
