java - Android 通知不发出声音或振动

Question

int icon = R.drawable.icon;  
Context context = getApplicationContext();    
CharSequence contentTitle = "My notification";  
CharSequence contentText = "Countdown Complete!";     
NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
Intent intent = new Intent();
Notification notification = new Notification(icon, "is completed!", System.currentTimeMillis());  
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
notification.setLatestEventInfo(context, contentTitle, contentText, pendingIntent);
long[] vibrate = {0,100,200,300};
notification.vibrate = vibrate;
notification.defaults |= Notification.DEFAULT_LIGHTS;
notification.defaults |= Notification.DEFAULT_SOUND; 
notificationManager.notify(myCountDown.getId(), notification);

此代码在我的 android 应用程序中，我收到通知但没有声音或振动。

我已经在多部手机上进行了测试，所有手机都在设置中打开并开启了声音和振动。我还确保我要求在 android list 中使用振动权限，但我仍然只收到通知...

我也试过:

notification.defaults = Notification.DEFAULT_ALL;

和

notification.defaults |= Notification.DEFAULT_VIBRATE;
notification.defaults |= Notification.DEFAULT_LIGHTS;
notification.defaults |= Notification.DEFAULT_SOUND;

我如何在通知中获得声音和振动？

不要忘记为铃声和通知启用振动设置。转到设置 ->声音。勾选“声音振动”。
