【转】Android WebKit 简单例子
FROM大牛BLOG：http://blog.csdn.net/woshishushangdezhu/archive/2009/07/29/4391961.aspx
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APIs。
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;
}
