避免重复报警在android

Question

嗨，那里我是新来的android开发即时通讯开发一个应用程序，它与报警notification，而我在特定的时间设置报警完全正常工作和报警正确通知，但报警notification重复在某些时候即时消息不重复它，我怎么能避免这个问题。

这是我的代码：

Intent intent = new Intent(this, AlarmReceiver.class); 
intent.putExtra("ti", name); 
intent.putExtra("id", id); 
PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT); 
AlarmManager alarmManager = (AlarmManager)getSystemService(Context.ALARM_SERVICE);  
final Calendar cal = Calendar.getInstance();   
switch(Cun.valueOf(repeat)) { 
case No:   
alarmManager.set(AlarmManager.RTC_WAKEUP, targetCal.getTimeInMillis(), pendingIntent); 
break; 
} 

Answer 1

后报警首次通知，通过取消：

Intent intent = new Intent(this, AlarmReceiver.class); 
intent.putExtra("ti", name); 
intent.putExtra("id", id); 
PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT); 
AlarmManager alarmManager = (AlarmManager)getSystemService(Context.ALARM_SERVICE); 
alarmManager.cancel (pendingIntent);
