前情提要
Android 8.1平臺SystemUI 導航欄載入流程解析
9.0 改動點簡要說明
1、新增 StatusBarMobileView 替代 SignalClusterView，用以控制信號欄顯示
同時增加的還有 StatusBarIconView、StatusBarWifiView
2、整體流程和 8.1 類似

先來看初始賦值的地方 MobileSignalController.java，在 notifyListeners() 方法中進行我們對應的定製，
最後通過 callback.setMobileDataIndicators() 將狀態值傳遞到 StatusBarSignalPolicy.java 解析顯示
