我目前有一个播放mp3文件的媒体播放器.当该文件完成后,代码是什么,以便它转到下一个url / mp3？

还有,是否有代码获取文件的名称并显示它？我该怎么做呢？

谢谢

看下面的代码：

package com.example.m3uplayer;
import android.app.Activity;
import android.media.AudioManager;
import android.media.MediaPlayer;
import android.net.Uri;
import android.os.Bundle;
import android.media.MediaPlayer.OnCompletionListener;
public class m3uPlayer extends Activity implements MediaPlayer.OnCompletionListener {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        //
        //http://dl.dropBox.com/u/24535120/AfroJack-UMF11-clip2.mp3
        //http://dl.dropBox.com/u/24535120/Avicii%20clip%201.mp3
        Uri myUri = Uri.parse("http://dl.dropBox.com/u/24535120/AfroJack-UMF11-clip2.mp3");
        MediaPlayer sdrPlayer = new MediaPlayer();
        try {
            sdrPlayer.setDataSource(this,myUri);//"http://mp1.somafm.com:8032");
            sdrPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
            sdrPlayer.prepare(); //don't use prepareAsync for mp3 playback
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        sdrPlayer.start();
    }
    @Override
    public void onCompletion(MediaPlayer sdrPlayer) {
        Uri myUri5 = Uri.parse("http://dl.dropBox.com/u/24535120/Avicii%20clip%201.mp3");
        try {
            sdrPlayer.setDataSource(this,myUri5);
            sdrPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
            sdrPlayer.prepare(); //don't use prepareAsync for mp3 playback
        } catch (IllegalArgumentException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (SecurityException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (IllegalStateException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        sdrPlayer.start();
    }
}
