如何在Android应用程序中使用XML播放歌曲？

Question

<?xml version="1.0" encoding="utf-8"?> 
<!-- generator="FeedCreator 1.7.2"--> 
<rss version="2.0"> 
    <strings> 
    <level>one</level> 
    </strings> 
    <item> 
    <contentitem> 
     <title>Song 1</title> 
     <view>Song 1</view> 
     <english>Song1.mp3</english> 
    </contentitem> 
    </item> 
    <item> 
    <contentitem> 
     <title>Song 2</title> 
     <view>Song 2</view> 
     <english>song2.mp3</english> 
    </contentitem> 
    </item> 
    <item> 
    <contentitem> 
     <title>Song 3</title> 
     <view>Song 3</view> 
     <english>song3.png</english> 
     <spanish>song3.png</spanish> 
    </contentitem> 
    </item> 
    <item> 
    <contentitem> 
     <title>Song 4</title> 
     <view>Song 4</view> 
     <english>song4.mp3</english> 
     <spanish>song4.mp3</spanish> 
    </contentitem> 
    </item> 
</rss> 

以上是我的XML文件我只想用这个XML文件播放音乐假设我正在访问第0个街区应用播放song1.mp3如果我正在访问第1街区应用播放song2.mp3等等......我麦汁中的功能，这样的....

android.view.View.OnClickListener spanish = new android.view.View.OnClickListener() { 
    public void onClick(View v) { 
    MediaPlayer m = MediaPlayer.create(Formulae.this, R.drawable.song1.mp3); 
    m.start(); 
  } 
}; 

上面的代码是静态的我怎样才能让它在动态（R.drawable.song1.mp3）根据所选块......，事情来形成XML。请帮助我，谢谢。

只是给你的想法

android.view.View.OnClickListener spanish = new android.view.View.OnClickListener() { 
    MediaPlayer mediaPlayer; 

    public void onClick(View v) { 
     // we want to create the mediaPlayer Instance 
     // just once 
     if(mediaPlayer==null) 
      mediaPlayer = new MediaPlayer(); 

     // try getting the new Title that should be played 
     String pathToNewTitle = getPathFromClickedViewItem(v); 
     // stop current Song 
     mediaPlayer.stop(); 
     try { 
      mediaPlayer.setDataSource(); 
     } catch (IllegalArgumentException e1) { 
      // implement this yourself 
     } catch (IOException e2) { 
      // implement this yourself 
     } 
     mediaPlayer.start(); 
    } 

    private String getPathFromClickedViewItem(View v) { 
     String path; 

     // you have to implement this yourself 
     // the idea is to determine the path 
     // for the mp3 that should be played 
     // when a specific view item is clicked 

     return path; 
    } 
}; 

在Android上播放音频视频 - >http://developer.android.com/guide/topics/media/index.html

阅读Android的XML文件 - >http://developer.android.com/reference/org/xml/sax/package-summary.html

，因为你知道你的我建议使用xpath - >http://developer.android.com/reference/javax/xml/xpath/package-summary.html

如果你不知道如何把这个问题，你应该先学习oo编程d java！
