Android--用Pull解析器将对象解析成xml文件及单元测试
新建工程，新建一个工具类PersonService，新建一个实体类Person，新建一个测试类Test
PerServiceTest类：
package com.mrzhu.pullparse;import java.io.OutputStream;import java.util.List;import org.xmlpull.v1.XmlSerializer;import android.util.Xml;public class PersonServiceTest {public void save(List<Person> persons, OutputStream out) throws Exception{XmlSerializer serializer = Xml.newSerializer();serializer.setOutput(out, "utf-8");serializer.startDocument("utf-8", true);serializer.startTag(null, "persons");for (Person person : persons) {serializer.startTag(null, "person");serializer.attribute(null, "personid", person.getPersonid());serializer.startTag(null, "name");serializer.text(person.getName());serializer.endTag(null, "name");serializer.startTag(null, "tel");serializer.text(person.getTel());serializer.endTag(null, "tel");serializer.startTag(null, "fax");serializer.text(person.getFax());serializer.endTag(null, "fax");serializer.startTag(null, "email");serializer.text(person.getEmail());serializer.endTag(null, "email");serializer.endTag(null, "person");}serializer.endTag(null, "persons");serializer.endDocument();out.flush();out.close();}}
Person类：
package com.mrzhu.pullparse;public class Person {private String personid;private String name;private String address;private String tel;private String fax;private String email;public String getPersonid() {return personid;}public void setPersonid(String personid) {this.personid = personid;}public String getName() {return name;}public void setName(String name) {this.name = name;}public String getAddress() {return address;}public void setAddress(String address) {this.address = address;}public String getTel() {return tel;}public void setTel(String tel) {this.tel = tel;}public String getFax() {return fax;}public void setFax(String fax) {this.fax = fax;}public String getEmail() {return email;}public void setEmail(String email) {this.email = email;}@Overridepublic String toString() {return "Person [personid=" + personid + ", name=" + name + ", address="+ address + ", tel=" + tel + ", fax=" + fax + ", email="+ email + "]";}public Person(String personid, String name, String address, String tel,String fax, String email) {super();this.personid = personid;this.name = name;this.address = address;this.tel = tel;this.fax = fax;this.email = email;}}
Test类（继承AndroidTestCase）：
1.在AndroidManifest.xml中的<application></application>标签中添加
<uses-library android:name="android.test.runner" />
2.<application></application>标签外添加
<instrumentation
android:name="android.test.InstrumentationTestRunner"
android:targetPackage="com.mrzhu.pullparse" >
</instrumentation>
android:targetPackage为测试类所在的包名
