我在寫一些提醒用戶的東西。用戶將為其事件設(shè)置提醒，當(dāng)時(shí)間到了時(shí)，將設(shè)置重復(fù)警報(bào)以觸發(fā)狀態(tài)欄通知。但是，在選擇通知或清除通知后，警報(bào)似乎不會停止。我不確定在何處取消此重復(fù)警報(bào)。以下是一些代碼：在我的主要活動(dòng)中設(shè)置重復(fù)警報(bào)alarmTime = Calendar.getInstance();Intent intent = new Intent(this, AlarmReceive.class);PendingIntent sender = PendingIntent.getBroadcast(this, 0, intent, 0);AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);alarmTime.add(Calendar.MINUTE,offset_time);//Schedule the alarmalarmManager.setRepeating(AlarmManager.RTC_WAKEUP, alarmTime.getTimeInMillis(), 30 * 1000, sender);在我的OnReceive方法中，我只在狀態(tài)欄中顯示通知并將標(biāo)記設(shè)置為 FLAG_AUTO_CANCELmanager = (NotificationManager) context.getSystemService(context.NOTIFICATION_SERVICE);// Set the icon, scrolling text and timestampNotification notification = new Notification(R.drawable.medical, text, System.currentTimeMillis());PendingIntent contentIntent = PendingIntent.getActivity(context, 0, i, 0);notification.flags = Notification.FLAG_AUTO_CANCEL;manager.notify(R.string.service_text, notification);當(dāng)用戶選擇通知或清除通知時(shí)，如何停止警報(bào)？

cancel()以AlarmManager與PendingIntent您使用的等效的方式調(diào)用setRepeating()：
Intent intent = new Intent(this, AlarmReceive.class);
PendingIntent sender = PendingIntent.getBroadcast(this, 0, intent, 0);
AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
alarmManager.cancel(sender);

我嘗試了各種方法，但無法使它起作用，所以我決定做一個(gè)骯臟的把戲。當(dāng)我想取消重復(fù)的鬧鐘時(shí)，我使用創(chuàng)建鬧鐘的相同方法（因此替換了舊的鬧鐘），然后立即將其取消。使用此方法，如果boolean變量設(shè)置為true，它將創(chuàng)建警報(bào)，它會替換并取消具有相同ID的替換：
static void CancelRepeatingAlarm(Context context, boolean creating){
//if it already exists, then replace it with this one
Intent alertIntent = new Intent(context, AlertReceiver.class);
PendingIntent timerAlarmIntent = PendingIntent
.getBroadcast(context, 100, alertIntent,PendingIntent.FLAG_CANCEL_CURRENT);
AlarmManager alarmManager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
if (creating){
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), INTERVAL, timerAlarmIntent);
}else{
alarmManager.cancel(timerAlarmIntent);
}

在中MainActivity，設(shè)置鬧鐘時(shí)間。如果要使用多個(gè)警報(bào)，請使用SharedPreferences來存儲它們各自的ID。這是代碼：
PendingIntent pendingIntent = PendingIntent.getBroadcast(MainActivity.this, _id,intent, PendingIntent.FLAG_UPDATE_CURRENT);
alarmManager = (AlarmManager) getSystemService(Activity.ALARM_SERVICE);
alarmManager.set(AlarmManager.RTC_WAKEUP, targetCal.getTimeInMillis(),
pendingIntent);
public static Context getContext() {
return mContext;
}
mContext=mainactivity.this;
您第二次Activity使用來自的相同ID SharedPreferences。在我的代碼中，我從ArrayList獲得ID Alarm_id。最后，您可以在此處使用MainActivity上下文MainActivity.getContext()。這是代碼：
AlarmManager alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
Intent intentAlarm = new Intent(AlarmListviewActivity.this,
MainActivity.class);
PendingIntent morningIntent = PendingIntent.getBroadcast(MainActivity.getContext(), Alarm_id.get(positon),
intentAlarm, PendingIntent.FLAG_CANCEL_CURRENT);
alarmManager.cancel(morningIntent);
morningIntent.cancel();
