3. Core function analysis and implementation of SystemUI drop-down status bar time format modification (1)

In the system systemui, its layout structure is actually relatively complex. It manages various services, navigation bar, status bar, recent list, drop-down menu, shutdown interface, etc. Among them, the navigation bar and status bar, and the recent list are used more. This is also what this blog post will focus on. Structurally speaking, both the drop-down menu and the status bar belong to the statusbar. The top-level super_status_bar.xml in the structure tree also belongs to the top-level
super_status_bar. After that, there will be two branches: status_bar_container and status_bar_expanded.
    The status_bar_container branch mainly presents the status bar interface. The status bar is subdivided into the left and right sides. The left is the notification bar, and the right is the status icon display of system functions.
    The status_bar_expanded branch mainly presents the drop-down menu interface.
