打开我的应用程序并选择要播放的第一首歌后，我的MediaPlayer动作OnCompleteListener并跳到下一首歌。这个小故障在打开应用程序后只出现一次并且非常烦人。任何想法如何我能解决这个问题吗？
我想我正在使用prepareListener。
mediaPlayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
@Override
public void onPrepared(MediaPlayer mp) {
mp.start();
}
});
mediaPlayer.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
@Override
public void onCompletion(MediaPlayer mp) {
if (currentPosition < musicUrl.size() - 1) {
currentPosition = currentPosition + 1;
URL = musicUrl.get(currentPosition);
Uri uri = Uri.parse(URL);
try {
mediaPlayer.stop();
mediaPlayer.reset();
mediaPlayer.setDataSource(URL);
mediaPlayer.prepareAsync();
musicController.setCurrentSong(myDataList.get(currentPosition));
} catch (IOException e) {
e.printStackTrace();
}
}
}
});

答案 0 :(得分：0)
我的问题的解决方案是调用mediaPlayer onErrorListener，当发生错误时，我正在使用相同的URL重试媒体播放器。
