取消当你有多个报警单个报警 [英] Cancelling a single alarm when you have multiple alarms

问题描述

我已经使用了相同的pendingIntent使用不同intentId每个设置多个报警。报警工作。现在我想取消特定的报警。如果我用cancel（）方法，我会最终取消所有报警。我想仅特定的一个被删除。另外，用户应该能够即使在第二或第三个发射取消此报警。由于当我推出来的第二次，我不会再有同样的pendingIntent对象。那么我有坚持的pendingIntent对象？如果是这样，怎么样？而如何从多个报警取消单个报警？

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?

推荐答案

您可以像这样，

在你的等待意向，你可以通过一个的唯一ID 在请求code

In your Pending Intent you can pass a unique ID in place of requestCode

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

和取消，您可以使用相同的唯一ID来取消它，使用相同的待定意向。

And to cancel you can use the same unique ID to cancel it, using the same Pending Intent.

am.cancel(pi);
