我正在开发一个应用程序，它会在特定时间和日期提醒用户特定事件。我已正确设置通知，但它们有时可以正常工作，有时则无效。
我正在使用put extra并获得额外的功能，将点击位置发送到我的接收器类（从BuddhaEvent类发送到Myreceiver类的位置）。因此，如果用户点击位置1，则应从消息类触发通知1。我把每个职位的日志声明都打电话请检查。
log语句的输出如下：
POSITION0 : 0
POSITION0 : 0
POSITION1: 1
POSITION0 : 0
POSITION2 : 2
这是显示4个通知的日志声明
POSITION0 : 0
POSITION0 : 0
POSITION1: 1
POSITION0 : 0
POSITION2 : 2
POSITION0 : 0
POSITION3 : 3
这里有一个模式，在通知之前总是调用0！
我不知道发生了什么事。第一个通知正常，但之后通知只是随机的。大多数时候通知2和3同时出现，有时2等待3来。 我注意到的另一个问题是，当我向下滑动通知时，所有通知都具有相同的传递时间。我为每个通知设置了不同的ID。
我在想的是，额外收费和额外收费都是错误的。如果有人能帮助我找出问题，我真的很感激。
更新：当我点击列表中的第一个项目时，通知1显示出来。如果我点击第2项，那么通知1和2在同一时间显示。当我点击第3项通知3和1时显示。 提前致谢
更新2：该程序每次都会调用，我决定改变现有的位置0以及现在只有一次通知显示（此时仅在通过时已经工作）但是当我尝试计划通知时事件同样出现问题（同时显示两个通知）。

答案 0 :(得分：0)
您应该使用setExact方法来存档警报触发的确切时间。
但主要的问题是，当捆绑中没有bundle.getInt("position0")==0时，true始终为position0，因为：
返回与给定键关联的值，如果没有映射，则返回0 给定密钥存在所需的类型。
所以，为了解决这个问题，请传递位置：
intent.putExtra("position", position);
然后像广播接收器那样检查它：
int position = bundle.getInt("position");
switch (position):
case 0:
utils.generateNotification(context);
break;
case 1:
utils.generateNotification1(context);
break;
