我有一个创建和取消警报的测试实现示例。
public void setTHEalarm(Calendar aCalendarToAlarm) {
int id;
Intent intent;
PendingIntent pendingIntent;
AlarmManager alarmManager;
//I create an unique ID for my Pending Intent based on fire time of my alarm:
id = Integer.parseInt(String.format("%s%s%s%s",
aCalendarToAlarm.get(Calendar.HOUR_OF_DAY),
aCalendarToAlarm.get(Calendar.MINUTE),
aCalendarToAlarm.get(Calendar.SECOND),
aCalendarToAlarm.get(Calendar.MILLISECOND))); //HASH for ID
intent = new Intent(this,AlarmReceiver.class);
intent.putExtra("id",id); //Use the id on my intent, It would be usefull later.
//Put the id on my Pending Intent:
pendingIntent = PendingIntent.getBroadcast(this,id,intent,0);
alarmManager = (AlarmManager)
this.getSystemService(Context.ALARM_SERVICE);
alarmManager.setInexactRepeating(AlarmManager.RTC_WAKEUP,aCalendarToAlarm.getTimeInMillis(),CustomDate.INTERVAL_MINUTE,pendingIntent);
Log.w(TAG+" Torrancio","Created alarm id: "
+id+" -> "
+CustomDate.dateToHumanString(aCalendarToAlarm.getTime()));
//Keep a reference in a previously declared field of My Activity (...)
this.idSaved = id;
}
//Now for canceling
public void setCancel() {
int id;
Intent intent;
PendingIntent pendingIntent;
AlarmManager alarmManager;
id = this.idSaved;
intent = new Intent(this,AlarmReceiver.class);
intent.putExtra("id",id);
pendingIntent = PendingIntent.getBroadcast(this,id,intent,PendingIntent.FLAG_CANCEL_CURRENT);
//Note I used FLAG_CANCEL_CURRENT
alarmManager = (AlarmManager) this.getSystemService(Context.ALARM_SERVICE);
alarmManager.cancel(pendingIntent);
Log.w(TAG+" Torrancio","Canceled->"+id);
}
需要3样东西,
- 相同类型的意图(在这种情况下,我们谈论的是AlarmManager)。
- 相同的 PendingIntent ID(保留 id 的引用,以某种方式保存)。
- 一个正确的标志(FLAG_CANCEL_CURRENT用于取消,不需要也不能完全是您在创建挂起意图时使用的标志 [因为我们使用取消标志进行 calcel,但不创建。 ])
