Android Pull 解析 XML

下面是效果图，代码中有详细解释，

res/raw/person.xml

<?xml version="1.0" encoding="UTF-8"?>  <persons>      <person id="001">          <name>张三</name>          <age>22</age>      </person>            <person id="002">          <name>李四</name>          <age>23</age>      </person>            <person id="003">          <name>王五</name>          <age>24</age>      </person>  </persons>

public class PullParse {   public static List<Person> parse(InputStream inputStream) throws Exception{    List<Person> persons=null;    Person person=null;    XmlPullParser parser=Xml.newPullParser();    parser.setInput(inputStream, "UTF-8");    int event=parser.getEventType();    while(event!=XmlPullParser.END_DOCUMENT){     switch(event){     //判断当前事件是否是文档开始事件     case XmlPullParser.START_DOCUMENT:      persons=new ArrayList<Person>();      break;     //判断当前事件是否是标签元素开始事件     case XmlPullParser.START_TAG:      //判断开始标签元素是否是book      if("person".equals(parser.getName())){       person=new Person();       person.setId(new Integer(parser.getAttributeValue(0)));      }      if(person!=null){                      if("name".equals(parser.getName())){                         person.setName(parser.nextText());                        }else if("age".equals(parser.getName())){                         person.setAge(new Integer(parser.nextText()));                        }                    }                    break;               //判断当前事件是否是标签元素结束事件              case XmlPullParser.END_TAG:               //判断结束标签元素是否是person                  if("person".equals(parser.getName())){                     persons.add(person);//将person添加到persons集合                     person = null;                    }                    break;     }     //进入下一个元素并触发相应事件     event = parser.next();    }        return persons;   }  }

public void onCreate(Bundle savedInstanceState) {          super.onCreate(savedInstanceState);          setContentView(R.layout.main);          btn=(Button) findViewById(R.id.button);          listView=(ListView) findViewById(R.id.listView);          btn.setOnClickListener(new OnClickListener(){     public void onClick(View arg0) {      try {       InputStream i =getResources().openRawResource(R.raw.person);       List<Person>persons = PullParse.parse(i);       for (Iterator iterator = persons.iterator(); iterator.hasNext();) {        Person person = (Person) iterator.next();        list.add(String.valueOf("ID："+person.getId()) + " 姓名： "          + person.getName() + " 年龄： " + person.getAge());       }      } catch (Exception e) {}      ArrayAdapter<String> adapter = new ArrayAdapter<String>(        getApplicationContext(),        android.R.layout.simple_list_item_1,        list);      listView.setAdapter(adapter);     }          });      }
