android xml解析添加到listview中的问题

一个问题不知什么原因，代码：

public class OtherActivity extends ListActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        //setContentView(R.layout.activity_other);
        
        //TextView tv1 = (TextView) findViewById(R.id.editText1);
        //获取存入的xml字符串
        String PaiMaiXML=load();
        List<String> data = new ArrayList<String>();
        data.add("车牌列表");
        
        List<Map<String, Object>> PaiMaiList = new ArrayList<Map<String, Object>>(); 
        Map<String, Object> PaiMaiMap = new HashMap<String, Object>();
        
        ByteArrayInputStream tInputStringStream = null;
        try
          {
          if (PaiMaiXML != null && !PaiMaiXML.trim().equals("")) {
           tInputStringStream = new ByteArrayInputStream(PaiMaiXML.getBytes());
          }
          }
          catch (Exception e) {
           // TODO: handle exception
           //tv1.setText(e.getMessage());
           return;
          }
        XmlPullParser parser = Xml.newPullParser();
          try {
           parser.setInput(tInputStringStream, "UTF-8");
           int eventType = parser.getEventType();
           
           //List<PaiMaiInfo> PaiMaiList=new ArrayList<PaiMaiInfo>;
           
           while (eventType != XmlPullParser.END_DOCUMENT) {
            switch (eventType) {
            case XmlPullParser.START_DOCUMENT:// 文档开始事件,可以进行数据初始化处理
            // persons = new ArrayList<Person>();
             break;
            case XmlPullParser.START_TAG:// 开始元素事件
             String name = parser.getName();
             
             if (name.equalsIgnoreCase("Base_tabletNumber")) {
              // currentPerson = new Person();
              // currentPerson.setId(new
              // Integer(parser.getAttributeValue(null, "id")));
                 
              //tv1.setText(parser.nextText());
                 PaiMaiMap.put("title", parser.nextText()); 
                 data.add(parser.nextText());

             } 
             if(name.equalsIgnoreCase("Base_Family"))
             {
                 PaiMaiMap.put("info", parser.nextText());
                 PaiMaiMap.put("img", R.drawable.ic_launcher); 
                 PaiMaiList.add(PaiMaiMap);
                 PaiMaiMap = new HashMap<String, Object>(); 
             }
//              else if (currentPerson != null) {
//              if (name.equalsIgnoreCase("loginlink")) {
//               currentPerson.setName(parser.nextText());// 如果后面是Text节点,即返回它的值
//              } else if (name.equalsIgnoreCase("errmsg")) {
//               currentPerson.setAge(new Short(parser.nextText()));
//              }
//             }
             break;
            case XmlPullParser.END_TAG:// 结束元素事件
//             if (parser.getName().equalsIgnoreCase("person")
//               && currentPerson != null) {
//              persons.add(currentPerson);
//              currentPerson = null;
//             }
             break;
            }
            eventType = parser.next();
            
           }
           tInputStringStream.close();
           // return persons;
          } catch (XmlPullParserException e) {
           // TODO Auto-generated catch block
           e.printStackTrace();
          } catch (IOException e) {
           // TODO Auto-generated catch block
           e.printStackTrace();
          }
          //ListView listView = (ListView) findViewById(R.id.listView1); 
          //listView.setAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1,data)); 
          //setContentView(listView); 
          SimpleAdapter adapter = new SimpleAdapter(this,PaiMaiList,R.layout.listcell, 
                    new String[]{"title","info","img"}, 
                    new int[]{R.id.title,R.id.info,R.id.img}); 
          setListAdapter(adapter); 

    }

当我把51行的注释掉就可以了，求真相

改成String wee=parser.nextText(); 也是有问题，难道nextText()的原因。。。

nextText()不能重复执行，具体原因 再研究
