本文介绍了这是我们的服务和活动之间沟通的最佳方式是什么?的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧! 问题描述 现在的活动可以连接到使用三种方式的服务:Now Activity can connect to services using one of three ways: BroadcastReceivers 使者 AIDLBroadcastReceiversMessengersAIDL我觉得BroadcastReceivers是沟通的最简单的方法,但我不知道为什么,何时使用其他方法吗?或者换句话说,在这种情况下的使者或AIDL会比broadcastreceivers使用的最佳做法是什么?I think that BroadcastReceivers is the easiest way to communicate but I'm wondering why and when to use other ways? or in other words in which cases messengers or AIDL will be the best practice to use than broadcastreceivers?推荐答案您可以使用的BroadcastReceiver 当你想要服务之间的通信和活动在应用程序。You can use BroadcastReceiver when you want the communication between Service and Activity in your application. 使者和 AIDL 的主要用于当你的应用程序需要传达给其他进程( IPC )。在这种情况下,你的界面应该有一个服务定义了处理程序,响应不同类型的消息的对象。Messenger's and AIDL's are mainly used when your application needs to communicate to other processes(IPC). In this case your interface should have a Service which defines a Handler that responds to different types of Message objects.现在使者和 AIDL 之间的区别是pretty的简单。当您使用使者后,它会将所有的请求到一个单独的线程。所以,你的服务不必是线程安全的。如果,你希望你的服务来,那么你可以使用 AIDL 直接同时处理多个请求。在这种情况下,你的服务必须能够多线程和建立线程安全的。事实上使者是在顶部 AIDL 实施。Now the difference between Messenger and AIDL is pretty simple. When you use Messenger, it queues all requests into a single thread. So your Service doesn't have to be thread safe. If, you want your Service to handle multiple requests simultaneously, then you can use AIDL directly. In this case, your Service must be capable of multi-threading and be built thread-safe. In fact Messenger is implemented on the top of AIDL.为了更好地理解一下绑定服务您也应该检查从答案BroadcastReceiver或者通过处理器通 这篇关于这是我们的服务和活动之间沟通的最佳方式是什么?的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持! 09-15 05:38
