The following code implements login without any xml configuration. It seems that there is no clear example of using xml configuration.

Xml configuration layout has obvious flexibility. The Code mainly implements logic functions and has some MVC ideas.
XML is the view configuration, the logic code is written into the class, and the Android event listening is the controller.
