在android中使用jsoup解析页面链接
使用了html解析器jsoup来获取页面所有链接，顺便试下把jsoup放进android中使用下，发现jsoup在android中能直接使用，测试例子代码(本文只作了简单测试)：
tt.jsp页面
<%@?page?language="java"?contentType="text/html;?charset=UTF-8"
????pageEncoding="UTF-8"%>
<!DOCTYPE?html?PUBLIC?"-//W3C//DTD?HTML?4.01?Transitional//EN"?"http://www.w3.org/TR/html4/loose.dtd"><html><head><meta?http-equiv="Content-Type"?content="text/html;?charset=UTF-8"><title>Insert?title?here</title></head><body>测试连接<a?href="http://www.blogjava.net/pengo/">penngo的博客</a><a?href="http://www.blogjava.net/">blogjava博客</a></body></html>
Activity01.java
import?org.jsoup.Jsoup;import?org.jsoup.nodes.Document;import?org.jsoup.nodes.Element;import?org.jsoup.select.Elements;import?android.app.Activity;import?android.os.Bundle;import?android.widget.TextView;public?class?Activity01?extends?Activity{
????@Override????public?void?onCreate(Bundle?savedInstanceState)
????{????????super.onCreate(savedInstanceState);????????????????setContentView(R.layout.main);????????TextView?tv?=?new?TextView(this);????????????????String?myString?=?null;????????StringBuffer?sff?=?new?StringBuffer();????????try????????{????????????Document?doc?=?Jsoup.connect("http://192.168.64.9:8099/AgentJava/tt.jsp").get();????????????Elements?links?=?doc.select("a[href]");????????????for(Element?link?:?links){????????????????sff.append(link.attr("abs:href")).append("??").append(link.text()).append("\n");
????????????}????????????myString?=?sff.toString();????????}????????catch?(Exception?e)????????{????????????myString?=?e.getMessage();????????????e.printStackTrace();????????}????????/*?将信息设置到TextView?*/????????tv.setText(myString);????????????????/*?将TextView显示到屏幕上?*/????????this.setContentView(tv);????}}
运行效果：
本文是在android2.2中开发测试，jsoup在android上使用和在jdk上使用是一样，不用改变代码。
