Suppose I have 10 lists and add a list event receiver itemadded event to these 10 lists, provided that this event provides the same functionality for all 10 lists. It is a headache to add the same event receiver to each list. If there are more than 10 event receivers in the list, copy the same event receiver n times.Code.
The following provides a method. For Mu
First, IntroductionBroadcast receiver is a broadcast receiver that receives custom and system anchors. It can also be called a listener.Broadcast intent, like intent, is the medium of communication, and unlike intent, broadcast intent is received by multiple components at the same time.Broadcast intent broadcast mechanism, broadcast sources emit messages, and through AMS (Activity Manager service), multiple

Golang value type and pointer type receiver has been confusing me, doing a few test memos here
Look at the receiver of the pointer type first:

As the name suggests, braodcast receiver is a broadcast receiver. It is similar to the time processing mechanism, but the event processing mechanism is program component-level (for example, the Click Event of a button ), the broadcast event processing mechanism is system-level. We can use intent to start a component, or use the sendbroadcast () method to initiate a system-level event broadcast to transmit m
Dynamic register broadcast receiver and dynamic broadcast ReceiverDynamically register broadcast recipients
This code serves the same purpose as the code below the static register broadcast receiver:
It is used to listen to call applications.

Golang the difference between a pointer receiver and a non-pointer receiver?
The biggest difference is that the pointer passes the reference to the image so that the property value of the image can be dynamically modified when the method is manipulated.
A non-pointer passes a copy of the image.
This should be similar to the
