Question

I have used the same pendingIntent to set multiple alarms using different intentId for each. the alarm is working. Now i want to cancel a particular alarm. If i use the cancel() method i would end up cancelling all the alarms. I want only a specific one to be deleted. Also the user should be able to cancel this alarm even during a second or a third launch. As in when i launch it the second time, i won t be having the same pendingIntent object. Would i have to persist the pendingIntent object? If so, how? and how do i cancel a single alarm from multiple alarms?

Answer 1

你可以这样做。

在您尚未获得许可的情况下,您可通过<代码>unique ID,取代requestCode。

PendingIntent pi = PendingIntent.getBroadcast(context, unique_id, i, 0);

取消后,你可以使用相同的独一无二的身份证,以取消该身份证,同时使用同样的待决身份。

am.cancel(pi);

这里需要作解释。

首先,你们应当为即将到来的意图创造独特的意图。为此,你可以建立一个习惯数据领域,说明你打算申请。我这样做的方式如下:

Intent intent = new Intent();
intent.setAction(ExampleAppWidgetProvider.MY_INTENT_ACTION);
Uri data = Uri.withAppendedPath(
                Uri.parse("myapp://myapp/Id/#"),
                String.valueOf(intentId));
intent.setData(data);

页: 1 Id将是您独特的意向识别符号。

接着,你发出警报管理人员通知照例。取消警报,请采取以下步骤。首先,你们应当像以往的法典样本那样,产生意图。然后,你根据这一意图制造了未决意图(你也制造了同样的预想,以引起警惕)。然后,你取消这一警告:

Intent intent = new Intent();
intent.setAction(ExampleAppWidgetProvider.MY_INTENT_ACTION);
Uri data = Uri.withAppendedPath(
                Uri.parse("myapp://myapp/Id/#"),
            String.valueOf(intentId));
intent.setData(data);


PendingIntent pendingIntent = PendingIntent.getBroadcast(
                context, 0, intent,
                PendingIntent.FLAG_UPDATE_CURRENT);
AlarmManager alarmManager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
alarmManager.cancel(pendingIntent);
