Android:使用 AlarmManager 设置所有 PendingIntent [英] Android: Get all PendingIntents set with AlarmManager

问题描述

我正在设置这样的闹钟:

I'm setting an alarm like this:

alarmManager.set(AlarmManager.RTC_WAKEUP, alarmTime, pendingEvent);

我有兴趣删除之前设置的所有警报，清除它们.

I'm interested in removing all the alarms that where previously set, clearing them.

有没有办法让我这样做或获取当前设置的所有警报，以便我可以手动删除它们?

Is there a way for me to do that or to get all the alarms that are currently set so that I can delete them manually ?

推荐答案

您需要创建待处理的意图，然后取消它

You need to create your pending intent and then cancel it

 AlarmManager alarmManager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);

    Intent updateServiceIntent = new Intent(context, MyPendingIntentService.class);
    PendingIntent pendingUpdateIntent = PendingIntent.getService(context, 0, updateServiceIntent, 0);

    // Cancel alarms
    try {
        alarmManager.cancel(pendingUpdateIntent);
    } catch (Exception e) {
        Log.e(TAG, "AlarmManager update was not canceled. " + e.toString());
    }
