How does MVP design a login interface?
First implement a get username, get user password, clear username, clear user password, show progressbar loading status, hide progressbar loading status, and jump to the main Activity and error callback
Login example:
Take a certain project of yours as an example. First, you must have a userbean class that manages basic user information, write basic attributes and corresponding get/set methods in the class, and extract the login into an interface (must be attribute name+password+server login information status callback), and implement it in Modle and interact with the server,
