我已阅读有关如何检查未决意图的警报是否存在的有关 stackoverflow 的问题。
我检查我的警报是否以这种方式存在：
boolean alarmUp = (PendingIntent.getBroadcast(context, 0,
new Intent("com.my.package.MY_UNIQUE_ACTION"),
PendingIntent.FLAG_NO_CREATE) != null);
我设置了一个警报并检查它是否存在，然后取消警报。警报实际上已取消，但如果再次运行上述语句，它仍然返回 true。
我已经在清单中静态注册了广播接收器。
我设置和取消闹钟的方法是这样的：
public static void cancelRecurringAlarm(Context context, String intentAction) {
Logger.mlog(DEBUG_TAG, "cancelRecurringAlarm called with intent " + intentAction);
Intent reminder = new Intent();
reminder.setClass(context, <receiverClassName>);
reminder.setAction(intentAction);
PendingIntent recurringReminder = PendingIntent.getBroadcast(context, 0, reminder, PendingIntent.FLAG_CANCEL_CURRENT);
AlarmManager alarms = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
alarms.cancel(recurringReminder);
}
public static void setRecurringAlarm(String intentAction, Context context, long timeInMs) {
Logger.mlog(DEBUG_TAG, "setRecurringAlarm called with intent " + intentAction);
Intent reminder = new Intent();
reminder.setClass(context, <receiverClassName>);
reminder.setAction(intentAction);
PendingIntent recurringReminder = PendingIntent.getBroadcast(context, 0, reminder, PendingIntent.FLAG_CANCEL_CURRENT);
AlarmManager alarms = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
alarms.setRepeating(AlarmManager.RTC, timeInMs, AlarmManager.INTERVAL_DAY, recurringReminder);
}
