前情提要
Android 8.1平台SystemUI 导航栏加载流程解析
9.0 改动点简要说明
1、新增 StatusBarMobileView 替代 SignalClusterView，用以控制信号栏显示
同时增加的还有 StatusBarIconView、StatusBarWifiView
2、整体流程和 8.1 类似
效果图
整体流程图
上代码
先来看初始赋值的地方 MobileSignalController.java，在 notifyListeners() 方法中进行我们对应的定制，
最后通过 callback.setMobileDataIndicators() 将状态值传递到 StatusBarSignalPolicy.java 解析显示

根据通用标准自定义显示规则
