android - 将通知设置为特定时间

Question

我希望我的通知在每天中午 12:00 运行。如何用时间替换 when 值？

NotificationManager nm = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
Notification notify = new Notification(R.drawable.icon,"Its Time to Eat",when);

Context context = GrubNOWActivity.this;
CharSequence title = "Its Time to Eat";
CharSequence details = "Click Here to Search for Restaurants";
Intent intent = new Intent(context,Search.class);
PendingIntent pending = PendingIntent.getActivity(context, 0, intent, 0);
notify.setLatestEventInfo(context, title, details, pending);
nm.notify(0,notify);

Answer 1

您可以使用警报管理器

Intent myIntent = new Intent(ThisApp.this , myService.class);     
AlarmManager alarmManager = (AlarmManager)getSystemService(ALARM_SERVICE);
pendingIntent = PendingIntent.getService(ThisApp.this, 0, myIntent, 0);

Calendar calendar = Calendar.getInstance();
calendar.set(Calendar.HOUR_OF_DAY, 12);
calendar.set(Calendar.MINUTE, 00);
calendar.set(Calendar.SECOND, 00);

alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), 24*60*60*1000 , pendingIntent);  //set repeating every 24 hours

并将通知放在 myService 类中！

该when参数用于对状态栏中的通知进行排序。您应该对您的应用程序进行编码，使其在所需时间触发通知。
