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
