Android使用Pull解析器解析xml文件的实现代码

2019年07月24日  | 移动技术网移动技术  | 我要评论

2个类：1个实体类person.java,1个继承activity的类

 

1.person.java

复制代码 代码如下:

package com.mrzhu.work_1_sax;

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;
 }

 @override
 public string tostring() {
  return "person [personid=" + personid + ", name=" + name + ", address="
    + address + ", tel=" + tel + ", fax=" + fax + ", email="
    + email + "]";
 }
}

2.继承activity的类：

复制代码 代码如下:

package com.mrzhu.work_1_sax;

import java.io.ioexception;
import java.io.inputstream;
import java.util.arraylist;
import java.util.list;

import javax.xml.parsers.parserconfigurationexception;
import javax.xml.parsers.saxparser;
import javax.xml.parsers.saxparserfactory;

import org.xml.sax.saxexception;
import org.xmlpull.v1.xmlpullparser;
import org.xmlpull.v1.xmlpullparserexception;

import android.app.activity;
import android.os.bundle;
import android.util.xml;
import android.view.view;
import android.widget.toast;

public class pullactivity extends activity {
    /** called when the activity is first created. */
    @override
    public void oncreate(bundle savedinstancestate) {
        super.oncreate(savedinstancestate);
        setcontentview(r.layout.main);
    }

    public void pull(view v){
     pullparse(); 
    }

    public void pullparse(){
     list<person> persons = null;
     person person = null;
     inputstream in = null;
     try {
      xmlpullparser pullparser = xml.newpullparser();
      in = getassets().open("person.xml");
   pullparser.setinput(in, "utf-8");
   int eventtype = pullparser.geteventtype();
   while(eventtype != xmlpullparser.end_document){
    string qname = pullparser.getname();
    switch(eventtype){
    case xmlpullparser.start_document:
     persons = new arraylist<person>();
     break;
    case xmlpullparser.start_tag:
     if("person".equalsignorecase(qname)){
      person = new person();
      person.setpersonid(pullparser.getattributevalue(null, "personid"));
     }else if("name".equalsignorecase(qname)){
      person.setname(pullparser.nexttext());
     }else if("address".equalsignorecase(qname)){
      person.setaddress(pullparser.nexttext());
     }else if("tel".equalsignorecase(qname)){
      person.settel(pullparser.nexttext());
     }else if("fax".equalsignorecase(qname)){
      person.setfax(pullparser.nexttext());
     }else if("email".equalsignorecase(qname)){
      person.setemail(pullparser.nexttext());
     }
     break;
    case xmlpullparser.end_tag:
     if("person".equalsignorecase(qname)){
      persons.add(person);
     }
     break;
    }
    eventtype = pullparser.next();
   }
   in.close();
  } catch (xmlpullparserexception e) {
   e.printstacktrace();
  } catch (ioexception e) {
   e.printstacktrace();
  }

     for (person person2 : persons) {
   toast.maketext(this, person2.tostring(), toast.length_short).show();
  }
    }
}

main.xml

复制代码 代码如下:

<?xml version="1.0" encoding="utf-8"?>
<linearlayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >

    <button
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:onclick="pull"
        android:text="pull" />

</linearlayout>

放在assets文件夹下的person.xml文件

复制代码 代码如下:

<?xml version="1.0" encoding="utf-8"?>
<people>
 <person personid="e01">
  <name>tony blair</name>
  <address>10 downing street, london, uk</address>
  <tel>(061) 98765</tel>
  <fax>(061) 98765</fax>
  <email>blair@everywhere.com</email>
 </person>
 <person personid="e02">
  <name>bill clinton</name>
  <address>white house, usa</address>
  <tel>(001) 6400 98765</tel>
  <fax>(001) 6400 98765</fax>
  <email>bill@everywhere.com</email>
 </person>
 <person personid="e03">
  <name>tom cruise</name>
  <address>57 jumbo street, new york, usa</address>
  <tel>(001) 4500 67859</tel>
  <fax>(001) 4500 67859</fax>
  <email>cruise@everywhere.com</email>
 </person>
 <person personid="e04">
  <name>linda goodman</name>
  <address>78 crax lane, london, uk</address>
  <tel>(061) 54 56789</tel>
