您可以使用以下代码在收到推送后显示警报:
String message = extras.getString("message");
String title = extras.getString("title");
Notification notif = new Notification(android.R.drawable.btn_star_big_on, message, System.currentTimeMillis() );
notif.flags = Notification.FLAG_AUTO_CANCEL;
notif.defaults |= Notification.DEFAULT_SOUND;
notif.defaults |= Notification.DEFAULT_VIBRATE;
Intent notificationIntent = new Intent(context, TestSampleApp.class);
notificationIntent.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);
PendingIntent contentIntent = PendingIntent.getActivity(context, 0, notificationIntent, 0);
notif.setLatestEventInfo(context, title, message, contentIntent);
String ns = Context.NOTIFICATION_SERVICE;
NotificationManager mNotificationManager = (NotificationManager) context.getSystemService(ns);
mNotificationManager.notify(1, notif);
把它放在接收推送的地方。
