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
