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,是否有代码来获取文件的名称并显示它?我该怎么做呢?
谢谢

请参阅下面的代码:
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/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();
}
}

您可以在媒体播放器中注册OnCompletionListener。收到回叫通知后,您需要在媒体播放器上调用reset()
,setDataSource
和prepare()
以获取下一个网址。
我不相信api中有任何内容可以告诉您媒体播放器使用的数据源。你需要自己跟踪它。
