java - 实例化重复警报后如何从 BroadcastReceiver 与 Activity 通信

Question

我正在创建一个循环警报，我希望它能够与调用它的 Activity 进行通信。我可以将 Intent 数据发送到 BroadcastReceiver 但在 BroadcastReceiver 运行时从 Activity 获取信息目前还不清楚。我需要 BroadcastReceiver 从调用它的 Activity 中轮询信息。

Answer 1

I am creating a recurring alarm, which I want to be able to communicate with the Activity that called it.

很可能“调用它的 Activity”不再存在，因为它已被销毁。

I need the BroadcastReceiver to poll information from the Activity that called it.

不，你不知道。您需要您的 Activity 和您的 BroadcastReceiver 来使用共享的持久数据模型，例如数据库或文件，可能通过静态数据成员进行缓存。
