Answer 1

您可以使用简单的 if-check 来处理暂停。试试这个:

MediaPlayer mp = MediaPlayer.create(this, Uri.parse(Environment.getExternalStorageDirectory().getPath()+ "/Music/jaihind.mp3"));
if(mp.isPlaying()) {
    mp.pause();
} else {
    mp.start();
}

注意:

mp = MediaPlayer.create(...);

已经在准备返回的 MediaPlayer，因此您不能再次调用 prepare(或其变体)(也不需要 onPreparedListener)。
