什么是利用广播接收器的推荐方式

问题描述:

我有下面的广播接收器,并显示它包含大量的注册操作。我的问题是如何处理包含大量操作的广播接收器的推荐方式?我应该把它们分开放在一个单独的文件中吗?或将它们放入服务中?什么是利用广播接收器的推荐方式

请指教。

更新

在情况下,我具有到接收器在另一文件分开,如何接收来自它的更新的通知,以及如何可以基于更新后的通知执行一个动作,ölike禁用一个例子中的“主要活动”按钮?

更好的,你把单独的一个文件。为每一个创建独特的方法。

但是如果在特定操作中有很长的任务,那么它应该在服务或线程上。

谢谢你的回答。但我可以让广播接收机作为服务吗?我的意思是,我可以克里特服务,并在其中我使用广播接收机,因为我希望一直收到通知?请咨询 – user2121

不,您不能将广播接收机作为服务。您必须为广播Receiver创建两个1类,并为Service创建1个。您可以使用广播接收通知服务基础。 –
