You can use a class to add the menu items (pass the activity as a parameter to the class). The menu click event will still fire on the activity module. You can use a single event for all the menu items and then delegate it to the class. This will allow you to share the code between all the modules:
B4X:
Sub Menu_Click
MenuHandlerClassInstance.MenuClick(Sender) 'sender will be the menu text
End Sub
It is this or I need to add the menu, items and click code in all the activities?
Thats what you normally do?
May exists a compiler INCLUDE(file) to include the same code in many modules?
