简单的联网解析ListView展示的例子

这个实体类

package com.nico.entity;

public class UserInfo {

	public String name;
	public String id;
	public String gender;
}

 

 

解析相关类

package com.nico.util;

import java.io.IOException;
import java.io.InputStream;
import java.net.HttpURLConnection;
import java.net.URL;
import java.util.ArrayList;

import org.xmlpull.v1.XmlPullParser;
import org.xmlpull.v1.XmlPullParserException;

import android.app.Activity;
import android.util.Xml;

import com.nico.entity.UserInfo;

public class ParserXml {

	private UserInfo user;
	private ArrayList<UserInfo> list;
	InputStream is = null;
	String url;

	public ParserXml() {

//		this.url = url;
		// act = actt;

	}

	public ArrayList<UserInfo> getInfo(InputStream is) {

		XmlPullParser parser = Xml.newPullParser();
		try {
			parser.setInput(is, "utf-8");

			int event = parser.getEventType();
			while (event != XmlPullParser.END_DOCUMENT) {
				switch (event) {
				case XmlPullParser.START_DOCUMENT:
					list = new ArrayList<UserInfo>();
					break;
				case XmlPullParser.START_TAG:
					if ("userinfo".equals(parser.getName())) {
						user = new UserInfo();
						user.id =parser.getAttributeValue(null,"id");

Item  xml<都是最简单的了>

 

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="wrap_content"
  android:layout_height="wrap_content">
  <TextView android:layout_width="60dip"
  android:layout_height="wrap_content"
  android:id="@+id/id"/>
    <TextView android:layout_width="130dip"
  android:layout_height="wrap_content"
  android:id="@+id/name"/>
    <TextView android:layout_width="130dip"
  android:layout_height="wrap_content"
  android:id="@+id/gender"/>
</LinearLayout>

 

主Main

 

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
	android:orientation="vertical" android:layout_width="fill_parent"
	android:layout_height="fill_parent">
	<LinearLayout android:layout_width="fill_parent"
		android:layout_height="wrap_content">
		<TextView android:layout_width="60dip" android:layout_height="wrap_content"
			android:text="id" />
		<TextView android:layout_width="130dip"
			android:layout_height="wrap_content" android:text="name" />
		<TextView android:layout_width="130dip"
			android:layout_height="wrap_content" android:text="gender" />
	</LinearLayout>
	<ListView android:layout_width="fill_parent"
		android:layout_height="wrap_content" android:id="@+id/list" />
</LinearLayout>

 

 

都是最简单的了，用来解析xml信息就不贴了。

大概意思就是联网解析一个xml文件，并在view中展示。

没有用什么图片信息的。
