当我点击音乐通知并运行活动时。当音乐改变时，textview的内容发生了变化，但是视图没有更新，但是当我独立运行一个活动时，一切正常并且查看更新。
在musicService类中：
PendingIntent contentPendingIntent = PendingIntent.getActivity
(this, 0, new Intent(this, MusicPlayer.class), 0);
builder.setContentTitle(mMedia.getTitleMedia())
.setContentText(mMedia.getSingerName())
.setContentIntent(contentPendingIntent)
.setSmallIcon(R.drawable.ic_notification)
.setVisibility(NotificationCompat.VISIBILITY_PUBLIC)
.addAction(restartAction)
.addAction(playPauseAction)
.addAction(nextMusic)
.setDeleteIntent(MediaButtonReceiver.buildMediaButtonPendingIntent(getApplicationContext(), PlaybackStateCompat.ACTION_STOP));
和我的活动课
