Question

我需要多次创建多个通知。应该出现通知的时间被提取到event_id等等。通知的时间在另一个类中设置。以下代码会发生什么情况，例如，对于在10:00设置的通知，10:00之后设置的所有通知也会同时出现。请帮忙。只需要显示正确的通知。不是未来的。

        for(int j=0;j<event_id.size();j++)
                        {
                                   if(Integer.parseInt(event_id.get(j).toString())>newEventID&&Long.parseLong(event_time.get(j).toString())>System.currentTimeMillis())
                            {
                                AlarmManager alarmManager = (AlarmManager)getSystemService(ALARM_SERVICE);//alarm manager
                                NotificationManager notificationManager=(NotificationManager)getSystemService(NOTIFICATION_SERVICE);
                                Notification note=new Notification(R.drawable.friendi_main_logo, event_desc.get(j).toString(), System.currentTimeMillis());
                                Intent mainScreenIntent=new Intent(getApplicationContext(),MainScreenActivity.class);
                                mainScreenIntent.putExtra("UserID", user_id);
                                int uniqueCode=0;
                                uniqueCode= Integer.parseInt(event_id.get(j).toString());//unique code for each pending intent
                                //separate pending intent for each alarm.. one alarm manager can invoke only one PI
                                PendingIntent ListOfNotification=PendingIntent.getActivity(getApplicationContext(), uniqueCode,mainScreenIntent,0); 
                                note.flags=Notification.FLAG_AUTO_CANCEL;
                                alarmManager.set(AlarmManager.RTC_WAKEUP, Long.valueOf(event_time.get(j).toString()), ListOfNotification);//invokes pending intent @ the event_time
                                note.setLatestEventInfo(getApplicationContext(), "Event: "+event_title.get(j).toString(), event_group.get(j).toString()+": "+event_desc.get(j).toString(),ListOfNotification );
//                              Uri path=Uri.parse("android.resource://" + getPackageName() + "/alarm_sms.mp3");
//                              note.sound=path;
                                note.defaults=Notification.DEFAULT_ALL;
                                notificationManager.notify(EVENT_NOTIFY_ID, note);
                                EVENT_NOTIFY_ID++;
                                flag=true;
                            }
                        }

Answer 1

所以..你做的是......

if(Integer.parseInt(event_id.get(j).toString())>newEventID&&Long.parseLong(event_time.get(j).toString())>System.currentTimeMillis())
  {

在这一行之后..

看到没有再次输入if循环... 比如像..

把

   j=event_id.size();

这只会出现一个通知..

Answer 2

尝试使用布尔值仅检查第一个触发器。每当你准备开火第二个时，都要真实。你处于for循环中，并且每次都在调用notificationManager.notify(EVENT_NOTIFY_ID, note);，因此所有通知都会被触发。

boolean fire_only_one=true;
    for(int j=0;j<event_id.size();j++)
                            {
                                       if(Integer.parseInt(event_id.get(j).toString())>newEventID&&Long.parseLong(event_time.get(j).toString())>System.currentTimeMillis())
                                {
                                    AlarmManager alarmManager = (AlarmManager)getSystemService(ALARM_SERVICE);//alarm manager
                                    NotificationManager notificationManager=(NotificationManager)getSystemService(NOTIFICATION_SERVICE);
                                    Notification note=new Notification(R.drawable.friendi_main_logo, event_desc.get(j).toString(), System.currentTimeMillis());
                                    Intent mainScreenIntent=new Intent(getApplicationContext(),MainScreenActivity.class);
                                    mainScreenIntent.putExtra("UserID", user_id);
                                    int uniqueCode=0;
                                    uniqueCode= Integer.parseInt(event_id.get(j).toString());//unique code for each pending intent
                                    //separate pending intent for each alarm.. one alarm manager can invoke only one PI
                                    PendingIntent ListOfNotification=PendingIntent.getActivity(getApplicationContext(), uniqueCode,mainScreenIntent,0); 
                                    note.flags=Notification.FLAG_AUTO_CANCEL;
                                    alarmManager.set(AlarmManager.RTC_WAKEUP, Long.valueOf(event_time.get(j).toString()), ListOfNotification);//invokes pending intent @ the event_time
                                    note.setLatestEventInfo(getApplicationContext(), "Event: "+event_title.get(j).toString(), event_group.get(j).toString()+": "+event_desc.get(j).toString(),ListOfNotification );
    //                              Uri path=Uri.parse("android.resource://" + getPackageName() + "/alarm_sms.mp3");
    //                              note.sound=path;
                                    note.defaults=Notification.DEFAULT_ALL;
    if(fire_only_one){                                
    notificationManager.notify(EVENT_NOTIFY_ID, note);
    fire_only_one=false;
    }                  
                  EVENT_NOTIFY_ID++;
                                    flag=true;
                                }
                            }


    fire_only_one=true;

此外，您可以通过在此处仅设置最相关的通知来更改逻辑，当用户通过单击第一个通知打开活动时，使用ALARM管理器设置第二个通知。
