Android 11.0 SystemUI 状态栏下拉快捷面板,添加“反色“快捷开关_androidsystemui下拉快捷键

一.功能需求:

Android 11.0 系统,在系统设置中,有个深色主题的模式,为了方便操作,需要把这个功能的快捷方式添加到下拉状态栏的快捷面板中.

二.涉及的核心代码路径

frameworks/base/packages/SystemUI/res/values/config.xml
frameworks/base/packages/SystemUI/src/com/android/systemui/qs/tileimpl/QSFactoryImpl.java
frameworks/base/packages/SystemUI/src/com/android/systemui/qs/tiles/ColorInversionTile.java

三.步骤分析

(1)在配制文件config.xml中,添加"反色"项的配置.

 <!-- The default tiles to display in QuickSettings -->
    <string name="quick_settings_tiles_default" translatable="false">
        wifi,bt,dnd,flashlight,rotation,battery,cell,airplane,cast,screenrecord
    </string>

在quick_settings_tiles_default 中配置的快捷方式图标,是一次按顺序显示的,需要添加的"反色"快捷开关为inversion.如果有排列需要,则可以按要求放在需求的位置,现在我是直接添加到末尾.

 <!-- The default tiles to display in QuickSettings -->
    <string name="quick_settings_tiles_default" translatable="false">
     +   wifi,bt,dnd,flashlight,rotation,battery,cell,airplane,cast,screenrecord,inversion
    </string>

(2)"反色"功能的核心代码在ColorInversionTile中实现,现在需要将"反色"添加到QSFactoryImpl.java中,这样,点击快捷面板中"反色"快捷开关时,能实现开启和关闭反正功能.
