Android9.0 SystemUI 网络信号栏定制修改
来源：cnblogs　　作者：cczheng　　时间：2019/11/15 8:41:54　　对本文有异议

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

vendor\mediatek\proprietary\packages\apps\SystemUI\src\com\android\systemui\statusbar\policy\MobileSignalController.java

  1. @Override
