前提：使用可以联网的模拟器或者手机调试

一，更改xml文件

<?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">
<TextView  android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="Hello World, MainActivity"/><WebView android:id="@+id/myWebView1" android:layout_height="330px" android:layout_width="300px" android:layout_x="7px"android:layout_y="90px"android:focusable="false"/></LinearLayout>

二，更改AndroidManifest.xml文件

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"package="tianshuai.webView"android:versionCode="1"android:versionName="1.0"><application android:label="@string/app_name" ><activity android:name="MainActivity"android:label="@string/app_name"><intent-filter><action android:name="android.intent.action.MAIN" /><category android:name="android.intent.category.LAUNCHER" /></intent-filter></activity></application>
<uses-permission android:name="android.permission.INTERNET"/>  --允许程序联网
</manifest> 

三，更改java文件

import android.app.Activity;
import android.media.MediaPlayer;
import android.os.Bundle;
import android.webkit.WebSettings;
import android.webkit.WebView;
import java.io.IOException;
import java.util.logging.Level;
import java.util.logging.Logger;public class MainActivity extends Activity
{private WebView mWebView;  private MediaPlayer mp;@Overridepublic void onCreate(Bundle savedInstanceState){super.onCreate(savedInstanceState);setContentView(R.layout.main);mWebView = (WebView) findViewById(R.id.myWebView1);       WebSettings webSettings = mWebView.getSettings();       webSettings.setJavaScriptEnabled(true);        mWebView.loadUrl("http://www.baidu.com");  new Thread(){@Overridepublic void run(){mp = new MediaPlayer();try {mp.setDataSource("http://fm111.img.xiaonei.com/tribe/20070613/10/52/A314269027058MUS.mp3 ");mp.prepare();} catch (IOException ex) {Logger.getLogger(MainActivity.class.getName()).log(Level.SEVERE, null, ex);} catch (IllegalArgumentException ex) {Logger.getLogger(MainActivity.class.getName()).log(Level.SEVERE, null, ex);} catch (IllegalStateException ex) {Logger.getLogger(MainActivity.class.getName()).log(Level.SEVERE, null, ex);}mp.start();}}.start();}
}
