我在播放音頻時媒體播放器有問題，即使我退出應用程序它也不會停止我如何發布此代碼？

Question

enter code here

mediaPlayer.setOnCompletionListener(new MediaPlayer.OnCompletionListener() { @Override

        public void onCompletion(MediaPlayer mp) {

            btPause.setVisibility(View.GONE);
            btPlay.setVisibility(View.VISIBLE);
            mediaPlayer.seekTo(0);

        }
    });

}
@SuppressLint("DefaultLocale")
private String convertFormat(int duration) {
    return String.format("%02d:%02d"
            , TimeUnit.MILLISECONDS.toMinutes(duration)
            ,TimeUnit.MILLISECONDS.toSeconds(duration) -
                    TimeUnit.MINUTES.toSeconds(TimeUnit.MILLISECONDS.toMinutes(duration)));
}

}

我認為您每次都在創建一個 Mediaplayer 實例。 確保不是實例化是

MediaPlayer mp;// above the onCreate section
mp=MediaPlayer.create(this, R.raw.animal_kit);

代替

MediaPlayer mp=MediaPlayer.create(this, R.raw.animal_kit);
