Hi team,
There are two interfaces, namely interfaceA and interfaceB, and interfaceB is a sub-interface of interfaceA.
In the sub interfaceB, two localVariables are defined, namely b1 and b2.
In the parent interfaceA, there is a button. I want to implement a function. When the button in interfaceA is clicked, b1 and b2 in interfaceB can be operated.
How to achieve it?
Is there a recommended solution?
Thanks a lot!
