客户反馈下拉状态栏后没有网速显示了

分析

状态栏是在SystemUI里面的主要去看这里面的代码就行了

代码位置

代码分析

下拉状态栏跟桌面状态栏并不是一个界面。下拉状态栏在quick_qs_status_icons.xml布局

桌面的是S:\lyz\7701_6113\mt6877_S0_V12\alps\vendor\mediatek\proprietary\packages\apps\SystemUI\res\layout\system_icons.xml

查询记录看桌面如何加的，模仿一下。下拉状态栏的布局控制是在QuickStatusBarHeader.java里，在这里初始化一下就可以啦
