CarSystemBar不像Android手机那样固定的顶部“状态栏”和底部“导航栏”,而是将StatusBar和NavigationBar都统称为SystemBar,可以通过如下配置为每侧最多配置一个“系统栏”。
- packages/apps/Car/SystemUI/res/values/config.xml
<!-- Configure which system bars should be displayed. --><bool name="config_enableTopSystemBar">true</bool><bool name="config_enableLeftSystemBar">false</bool><bool name="config_enableRightSystemBar">false</bool><bool name="config_enableBottomSystemBar">true</bool><!-- Configure the type of each system bar. Each system bar must have a unique type. --><!-- STATUS_BAR = 0--><!-- NAVIGATION_BAR = 1--><!-- STATUS_BAR_EXTRA = 2--><!-- NAVIGATION_BAR_EXTRA = 3--><integer name="config_topSystemBarType">0</integer><integer name="config_leftSystemBarType">2</integer><integer name="config_rightSystemBarType">3</integer><integer name="config_bottomSystemBarType">1</integer>
- 默认显示Top&Bottom
- 显示左边栏
