根据Google上说。你可以在你的应用程序中调用Webkit工具，可以浏览一个www的页面，这一点都不假，下面来看看，原理我就不说了。大家可以看看API.
我给个简单的上网例子给大家体验下吧。我试验过，可以成功的。
package com.gggeye.android;
import android.app.Activity;
import android.os.Bundle;
import android.os.Handler;
import android.os.Message;
import android.webkit.DownloadListener;
import android.webkit.WebView;
public class WebViewDemo extends Activity {
/** Called when the activity is first created. */ @Override
public void onCreate(Bundle icicle) {
super.onCreate(icicle);
setContentView(R.layout.main);
webView1 = new WebView(this); webView1 .loadData( "<html><body>Can I focus?<br /><a href=\"#\">No I cannot!</a>.</body></html>", "text/html", "utf-8"); this.setContentView(webView1); Logger.info("Download Faild _=> " + webView1.canGoBack()); webView = new WebView(this); webView.loadUrl("http://www.3geye.net"); //webView.setDownloadListener(new WebDownloadListener()); new Thread(new WebDownloadListener(this)).start(); } WebView webView1; class WebDownloadListener implements Runnable, DownloadListener { WebViewDemo wd; WebDownloadListener(WebViewDemo wd){ this.wd = wd; } public void run() { int j=0; StringBuffer sb = new StringBuffer(); sb.append("正在连接网络"); while (true) { try { Thread.sleep(4 * 1000); j++; sb.append("."); webView1 = new WebView(wd); webView1.loadData("<html><body><font color=\"red\">" + sb.toString() + " </font></html>", "text/html", "utf-8"); Message msg = mHandler.obtainMessage(); mHandler.sendMessage(msg); } catch (Throwable e) { Logger.info(e.toString()); e.printStackTrace(); } if (j== 3) { webView1 = null; Message msg = mHandler.obtainMessage(); mHandler.sendMessage(msg); break; } } } public void onDownloadFailed(String arg0, int arg1) { Logger.info("Download Faild _=> " + arg0); } public void onDownloadFinished(String arg0) { Logger.info("Download Finished => " + arg0); setContentView(webView); } public void onDownloadStart(String arg0, String arg1, long arg2, Message arg3, Message arg4) { Logger.info("Download Faild _=> " + arg0); } public void onDownloadSuspended(String arg0, Message arg1) { Logger.info("Download Faild _=> " + arg0); } } Handler mHandler = new Handler(){ @Override public void handleMessage(Message msg) { super.handleMessage(msg); //invalidate(); if(webView1 == null) setContentView(webView); else setContentView(webView1); } }; WebView webView = null; } 小结：简单实现Android WebKit实例的内容介绍完了，希望通过Android WebKit实例内容的学习能对你有所帮助！
