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
