Android Media player OncompletionListener播放下一首歌而不是第二首歌

Question

我有一个带有音乐播放器的应用程序，我正在使用@override方法OnCompletionListener来听音乐完成并传递给下一首歌曲，波纹管代码可以正常工作，但是在第二首歌曲中完成OncompletionListener时没有调用再次和音乐在完成时停止，如何不断传递给下一首歌？

OnCompletionListener

mediaPlayer.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
                          @Override
                          public void onCompletion(MediaPlayer mp) {
                              NextSong();
                          }
                      });

NextSong 方法

public void NextSong (){

    num = posicion++;

    if (MainActivity.num <= MainActivity.listaArray.size() - 2) {

        mediaPlayer.reset();
        uri = Uri.parse(String.valueOf(archivosMp3[num + 1]));
        mmr.setDataSource(String.valueOf(archivosMp3[num + 1]));  

        mediaPlayer = mediaPlayer.create(Servicio_Reproductor.this, MainActivity.uri);
        mediaPlayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
            @Override
            public void onPrepared(MediaPlayer mp) {

                mediaPlayer.start();
            }
        });

试试这个，

    public class MediaplayerActivity extends Activity implements OnCompletionListener 
    {

        @Override
        protected void onCreate(Bundle savedInstanceState) {

        mMediaPlayer.setOnCompletionListener(this);
        }

        @Override
        public void onCompletion(MediaPlayer mp) {

        .
        .
        .
         mediaPlayer = mediaPlayer.create(Servicio_Reproductor.this, MainActivity.uri);
            mediaPlayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
                @Override
                public void onPrepared(MediaPlayer mp) {
                    mMediaPlayer.setOnCompletionListener(this);
                    mediaPlayer.start();
                }
            });

        }
    }
