صنع كائن البناء الخاص بالإشعار من الصنف Notification.Builder

Notification.Builder mBuilder = new Notification.Builder(this);

تخصيص الحد الأدنى من الخصائص للإشعار

• عنوان الإشعار.
• المحتوى الخاص بالإشعار.

mBuilder.setSmallIcon(R.drawable.msg_icon);

mBuilder.setContentTitle("New Message");

mBuilder.setContentText("Hi, This is the message text.");

بناء الإشعار بالخصائص السابقة

Notification notif = mBuilder.build();

إظهار الإشعار في درج الإشعارات

NotificationManager notifyMngr = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);

int notificationId = 103;

notifyMngr.notify(notificationId, notif);
