【Android】入门级连接网络示例： 网页浏览和播放网络MP3

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;
    @Override
    public 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()
        {
            @Override
         public 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();

    }
}
