android——使用pull解析xml檔案

1、persons.xml

   將persons.xml檔案放到src目錄下。其代碼如下：

<?xml version='1.0' encoding='UTF-8' standalone='yes' ?><persons><person id="1"><name>範冰冰</name><age>31</age></person><person id="2"><name>林志玲</name><age>38</age></person><person id="3"><name>章澤天</name><age>20</age></person></persons>

2、Person

建立一個名叫Person的javabean，代碼如下：

package com.njupt.xml1;public class Person {private Integer id;private String name;private Integer age;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 Integer getAge() {return age;}public void setAge(Integer age) {this.age = age;}@Overridepublic String toString() {return "Person [id=" + id + ", name=" + name + ", age=" + age + "]";}public Person() {super();}public Person(Integer id, String name, Integer age) {super();this.id = id;this.name = name;this.age = age;}}

3、PersonService

    在這裡使用android中已經整合的pull來解析xml檔案,代碼如下：

package com.njupt.xml1;import java.io.InputStream;import java.util.ArrayList;import java.util.List;import org.xmlpull.v1.XmlPullParser;import org.xmlpull.v1.XmlPullParserException;import android.util.Xml;public class PersonService {public List<Person> loadPersons(InputStream in) throws Exception{XmlPullParser parser = Xml.newPullParser();parser.setInput(in,"UTF-8");List<Person> persons = new ArrayList<Person>();Person p = null;for(int type = parser.getEventType() ; type != XmlPullParser.END_DOCUMENT; type = parser.next()){if( type == XmlPullParser.START_TAG){if( parser.getName().equals("person")){p = new Person();String id = parser.getAttributeValue(0);p.setId(Integer.parseInt(id));persons.add(p);}else if(parser.getName().equals("name")){String name = parser.nextText();p.setName(name);}else if(parser.getName().equals("age")){String age = parser.nextText();p.setAge(Integer.parseInt(age));}               }}return persons;}}

==================================================================

另附上android中測試時，xml中需要配置的兩段代碼：

 <instrumentation        android:name="android.test.InstrumentationTestRunner"        android:targetPackage="com.njupt.xml1" />    <uses-library android:name="android.test.runner" />

最後啟動並執行結果是：
