正在嘗試安排一個通知,其中包含所需的時間,如果在10秒後,我想要的時間是下面的代碼,但我不知道爲什麼它立即顯示通知,我是否做錯了什麼?或缺少什麼,請糾正我,如果我錯了任何地方,和現在用藍疊模擬器測試(內置版本4.4.2跟蹤API 19)通知立即顯示
notification = new NotificationCompat.Builder(this);
notification.setAutoCancel(true);
AlarmManager alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
Intent notificationIntent = new Intent("android.media.action.DISPLAY_NOTIFICATION");
notificationIntent.addCategory("android.intent.category.DEFAULT");
PendingIntent broadcast = PendingIntent.getBroadcast(this, 100, notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);
Calendar cal = Calendar.getInstance();
cal.add(Calendar.SECOND, 10);
alarmManager.setExact(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), broadcast);
// why its showing up instantly insted of after 10 seconds
//alarmManager.setExact(AlarmManager.RTC_WAKEUP,20,broadcast);
Intent intent = new Intent(this , MainActivity.class);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0 , intent , PendingIntent.FLAG_UPDATE_CURRENT);
Intent switchIntent = new Intent(this, switchButtonListener.class);
PendingIntent pendingSwitchIntent = PendingIntent.getBroadcast(this, 0, switchIntent, 0);
notification.setSmallIcon(R.drawable.ok);
notification.setWhen(20);
notification.setTicker("you've got a meesage");
notification.setContentTitle("new message");
notification.setContentText("wanna take a ride?");
// notification.setContentIntent(pendingIntent);
NotificationManager notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
notificationManager.notify(uniqueID, notification.build());
