SAX（simple API for XML）是一种XML解析的替代方法。相比于DOM，SAX是一种速度更快，更有效的方法。

在res资源目录下创建一个叫做raw的文件夹，在文件夹中创建如下的xml文件

创建该xml对应的实体类，

package com.example.entity;public class Persons{    private Integer id;    private String name;    private String age;    private String sex;    public Persons()    {            }    public Persons(Integer id, String name, String age, String sex)    {        super();        this.id = id;        this.name = name;        this.age = age;        this.sex = sex;    }    public Integer getId()    {        return id;    }    public void setId(Integer id)    {        this.id = id;    }    public String getName()    {        return name;    }    public void setName(String name)    {        this.name = name;    }    public String getAge()    {        return age;    }    public void setAge(String age)    {        this.age = age;    }    public String getSex()    {        return sex;    }    public void setSex(String sex)    {        this.sex = sex;    }}

package com.example.entity;public class Persons{    private Integer id;    private String name;    private String age;    private String sex;    public Persons()    {            }    public Persons(Integer id, String name, String age, String sex)    {        super();        this.id = id;        this.name = name;        this.age = age;        this.sex = sex;    }    public Integer getId()    {        return id;    }    public void setId(Integer id)    {        this.id = id;    }    public String getName()    {        return name;    }    public void setName(String name)    {        this.name = name;    }    public String getAge()    {        return age;    }    public void setAge(String age)    {        this.age = age;    }    public String getSex()    {        return sex;    }    public void setSex(String sex)    {        this.sex = sex;    }}

MVC思想中创建c这一层，也就是控制层，

package com.example.oper;import java.io.InputStream;import java.util.ArrayList;import java.util.List;import javax.xml.parsers.SAXParser;import javax.xml.parsers.SAXParserFactory;import org.xml.sax.Attributes;import org.xml.sax.SAXException;import org.xml.sax.helpers.DefaultHandler;import com.example.entity.Persons;public class SaxPar{    private List
     
       list;    private String flag;    public List
      
        parer(InputStream is) throws Exception    {        //生成该类的对象        MyDefaultHandler myDefaultHandler = new MyDefaultHandler();        //这个方法跟dom有点类似，都是要创建一个工厂，然后实例化        SAXParserFactory saxParserFactory = SAXParserFactory.newInstance();        SAXParser saxParser = saxParserFactory.newSAXParser();        //将is流读进来进行操作        saxParser.parse(is, myDefaultHandler);                return myDefaultHandler.getList();    }        private class MyDefaultHandler extends DefaultHandler    {        private List
       
         list;        private Persons p;        public List
        
          getList()        {            return list;        }        @Override        public void characters(char[] ch, int start, int length)                throws SAXException        {            if(flag != null)            {                if(flag.equals("name"))                {                    p.setName(new String(ch,start,length));                }                if(flag.equals("sex"))                {                    p.setSex(new String(ch,start,length));                }                                if(flag.equals("age"))                {                    p.setAge(new String(ch,start,length));                }                            }        }        @Override        public void endElement(String uri, String localName, String qName)                throws SAXException        {            if(localName.equals("person"))            {                list.add(p);            }            flag = null;        }        @Override        public void startDocument() throws SAXException        {                        list = new ArrayList
         
          ();        }        @Override        public void startElement(String uri, String localName, String qName,                Attributes attributes) throws SAXException        {                        if(localName.equals("person"))            {                p = new Persons();                p.setId(Integer.parseInt(attributes.getValue(0)));            }            flag = localName;        }            }}
         
        
       
      
     

在activity中应用

package com.example.sax;import java.io.InputStream;import java.util.ArrayList;import java.util.List;import android.app.Activity;import android.os.Bundle;import android.widget.ArrayAdapter;import android.widget.ListView;import com.example.entity.Persons;import com.example.oper.SaxPar;public class MainActivity extends Activity{    private List
     
       list;    private ListView mListView;    @Override    protected void onCreate(Bundle savedInstanceState)    {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);                mListView = (ListView)findViewById(R.id.listView1);        List
      
        mData = new ArrayList
       
        ();                InputStream is =getResources().openRawResource(R.raw.persons);        try        {            List
        
          list = new SaxPar().parer(is);            for (Persons person : list)            {                mData.add(person.getId()+"-"+person.getName()+"-"+person.getSex()+"-"+person.getAge());            }                    } catch (Exception e)        {            // TODO Auto-generated catch block            e.printStackTrace();        }                        mListView.setAdapter(new ArrayAdapter
         
          (MainActivity.this, android.R.layout.simple_list_item_1,mData));            }}
