android本地定时通知

android本地通知略有不同，分为立即触发和延时触发

1.即时通知

android默认的Notification为立即触发

　　　　　　  Intent intent = new Intent(Intent.ACTION_VIEW);　　　　　　  intent.addCategory(Intent.CATEGORY_LAUNCHER);            intent.setClass(_gameActivity, _gameActivity.getClass());            intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK|Intent.FLAG_ACTIVITY_RESET_TASK_IF_NEEDED);            PendingIntent content = PendingIntent.getActivity(context, 0, intent, 0);            final NotificationManager notiMgr = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);            final Notification noti = new Notification(R.drawable.icon, notiResult.getPayload(), System.currentTimeMillis());            String app_name = _gameActivity.getResources().getString(R.string.app_name);            noti.setLatestEventInfo(context, app_name, notiResult.getPayload(), content);            notiMgr.notify(atomicInteger.incrementAndGet(), noti);

2.延时触发

想让一定时间后再触发通知，其实是用系统的AlarmManager来实现的。

具体的AlarmManager解释参考

添加一个ALARM_SERVICE

/*     * name:通知名字，作为通知id使用     * content：通知内容     * time：倒时时（秒）     * */    public static void addLocalNotication(String name, String content, int time)    {        Calendar cal = Calendar.getInstance();        cal.setTimeInMillis(System.currentTimeMillis());          cal.add(Calendar.SECOND, (int) time);          Activity activity = _gameActivity;        Intent intent = new Intent(activity, NotificationReceiver.class);        intent.setClass(activity, NotificationReceiver.class);          intent.setData(Uri.parse(name));

　　　　　　intent.putExtra("msg", "play_hskay");

intent.putExtra("content", content);

             PendingIntent pi = PendingIntent.getBroadcast(activity, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);                     AlarmManager am = (AlarmManager) activity.getSystemService(Context.ALARM_SERVICE);        am.set(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), pi);    }

添加一个系统通知类，用于在倒计时间到时，接收系统轮询通知
