更新后Android通知setContentText消失

我有一个通知，显示有关在我的应用程序中播放的歌曲的信息。一切似乎都奏效，但是当我更新通知时，setContentText消失了。更新后Android通知setContentText消失

这里是我的代码：

public void buildnotification() { 

Intent notificationIntent = new Intent(getApplicationContext(), Playback.class); 
notificationIntent.setAction(Constants.ACTION.MAIN_ACTION); 
notificationIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK 
     | Intent.FLAG_ACTIVITY_CLEAR_TASK); 
PendingIntent pendingIntent = PendingIntent.getActivity(getApplicationContext(), 0, 
     notificationIntent, 0); 

Intent previousIntent = new Intent(getApplicationContext(), MediaPlayerService.class); 
previousIntent.setAction(Constants.ACTION.PREV_ACTION); 
PendingIntent ppreviousIntent = PendingIntent.getService(getApplicationContext(), 0, 
     previousIntent, 0); 

Intent playIntent = new Intent(getApplicationContext(), MediaPlayerService.class); 
playIntent.setAction(Constants.ACTION.PLAY_ACTION); 
PendingIntent pplayIntent = PendingIntent.getService(getApplicationContext(), 0, 
     playIntent, 0); 

Intent nextIntent = new Intent(getApplicationContext(), MediaPlayerService.class); 
nextIntent.setAction(Constants.ACTION.NEXT_ACTION); 
PendingIntent pnextIntent = PendingIntent.getService(getApplicationContext(), 0, 
     nextIntent, 0); 

Bitmap icon = BitmapFactory.decodeResource(getResources(), 
     R.mipmap.coloredlogo); 
NotificationManager mNotificationManager = 
     (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE); 

int notifyID = 1; 
NotificationCompat.Builder mNotifyBuilder = new NotificationCompat.Builder(this); 
mNotifyBuilder.setContentTitle("Scripture Singer") 
     .setTicker("Scripture Singer") 
     .setContentText(dName) 
     .setStyle(new NotificationCompat.MediaStyle()) 
     .setSmallIcon(R.mipmap.logonowords) 
     .setLargeIcon(Bitmap.createScaledBitmap(icon, 128, 128, false)) 
     .setContentIntent(pendingIntent) 
     .setOngoing(true); 

mNotifyBuilder.addAction(R.mipmap.ic_skip_previous_black_48dp, "Previous", ppreviousIntent); 

//changes play and pause 
if (mp.isPlaying()) { 
    mNotifyBuilder.addAction(R.mipmap.ic_pause_black_48dp, "Pause", 
      pplayIntent); 
} else { 
    mNotifyBuilder.addAction(R.mipmap.ic_play_arrow_black_48dp, "Play", 
      pplayIntent); 
} 

mNotifyBuilder.addAction(R.mipmap.ic_skip_next_black_48dp, "Next", pnextIntent); 

mNotificationManager.notify(notifyID, mNotifyBuilder.build()); 
}

难道你们有什么想法，为什么这可能是这样吗？

如何更新通知？你能粘贴代码吗？ –

我只是调用buildnotification（）。 – MJDude

您是否在每次调用buildnotification（）时检查了“dName”是否正在更改？ –

对不起。我从一个不再有变量的意图中回想一个intent.getStringExtra（）。尽管感谢您的帮助。
