在动态注册广播接收器的onReceive方法时，它总是被调用吗？

[英]Is a BroadcastReceiver's onReceive method always called the moment it gets registered dynamically?

I noticed that my wifi state BroadcastReceiver gets triggered everytime I register it in onResume with registerBroadcastReceiver . 我注意到，我的无线状态广播接收器被触发，每次我用它注册在的onResume registerBroadcastReceiver 。 Is that the default behavior? 这是默认行为吗？

Some broadcasts are sticky. 有些广播是粘性的。 This means that they'll 'stick' around after being broadcast so that new receivers immediately receive them when they register. 这意味着它们在广播后会“停留”在周围，以便新接收者在注册后立即接收它们。

An intent that is used with sticky broadcast, is called as sticky intent. 与粘性广播一起使用的意图称为粘性意图。 This intent will stick with android system for future broadcast receiver requests. 此意图将与android系统保持一致，以用于将来的广播接收器请求。

BroadcastReceiver onReceive（）在动态注册时不调用 - BroadcastReceiver onReceive() not Called when registered dynamically

不会调用BroadcastReceiver的onReceive方法 - BroadcastReceiver's onReceive method is not called

BroadcastReceiver的onReceive（）方法永远不会被调用 - method onReceive() of BroadcastReceiver never gets called

动态注册的广播接收器的 onReceive() 钩子方法没有被调用 - Dynamically registered broadcast receiver's onReceive() hook method is not called

从不调用BroadcastReceiver的“onReceive”方法 - BroadcastReceiver's “onReceive” method is never Called

没有调用BroadcastReceiver的onReceive方法 - BroadcastReceiver's onReceive method is not getting called

没有调用BroadcastReceiver的onReceive方法 - BroadcastReceiver's onReceive method is not being called

从不调用BroadcastReceiver中的onReceive方法 - The method onReceive in BroadcastReceiver is never called

注册BroadcastReceiver后，OnReceive不会被调用 - OnReceive is not called even after BroadcastReceiver is registered

没有调用BroadcastReceiver的onReceive方法 - onReceive method of BroadcastReceiver is not getting called
