Question

我正在尝试用mediaPlayer.setOnCompletionListener()播放下一首歌，但它只播放下一首歌，之后歌曲结束了媒体播放器停止。如何让媒体播放器一直播放？

    Intent i = getIntent();
    Bundle b = i.getExtras();
    mySongs = (ArrayList)b.getParcelableArrayList("songList");
    position = b.getInt("pos",0);
    u = Uri.parse(mySongs.get(position).toString());
    mediaPlayer = MediaPlayer.create(getApplicationContext(), u);
    mediaPlayer.start();

 mediaPlayer.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
            @Override
            public void onCompletion(MediaPlayer mp) {
                    mediaPlayer.stop();
                try {
                    mediaPlayer.prepare();
                } catch (IOException e) {
                    e.printStackTrace();
                }
                u = Uri.parse(mySongs.get(position + 1).toString());
                    mediaPlayer = MediaPlayer.create(getApplicationContext(), u);
                    mediaPlayer.start();
            }
        });

您无需等到onCompletion。只需一次创建两个玩家，然后使用setNextMediaPlayer排队第二个玩家

u1 = Uri.parse(mySongs.get(position).toString());
u2 = Uri.parse(mySongs.get(position + 1).toString());
mediaPlayer = MediaPlayer.create(getApplicationContext(), u1);
mediaPlayerNext = MediaPlayer.create(getApplicationContext(), u2);
mediaPlayer.setNextMediaPlayer(mediaPlayerNext);

并且您在第二首歌之后没有收到onCompletion，因为您将mediaPlayer值替换为对没有收听者设置的新播放器的引用。将mediaPlayer.setOnCompletionListener()添加到onCompletion handler。你也不需要准备旧玩家

Android meediaplayer会自动播放下一首歌吗？
