RK3576 Android14 状态栏和导航栏增加显示控制功能

问题背景：

因为RK3576 Android14用户需要手动控制状态栏和导航栏显示隐藏控制，包括对锁屏后下拉状态栏的屏蔽，在设置功能里增加此功能的控制，故参考一些博客完成此功能，以下是具体代码路径的修改内容。

解决方案：

1、修改系统默认配置

代码位置：device/rockchip/rk3576/device.mk

PRODUCT_PROPERTY_OVERRIDES += \
+    persist.sys.statusbar.enable=true \
+    persist.sys.navigationbar.enable=true

2、修改SystemUI

android/frameworks/base/packages/SystemUI/AndroidManifest.xml

    <protected-broadcast android:name="com.android.systemui.action.ACTION_LAUNCH_MEDIA_OUTPUT_BROADCAST_DIALOG" />+    <!-- For statusbar show or not -->
+    <protected-broadcast android:name="com.systemui.statusbar.show" />
+    <protected-broadcast android:name="com.systemui.statusbar.hide" />
+    <!-- For NavigationBar show or not -->
+    <protected-broadcast android:name="com.systemui.navigationbar.show" />
+    <protected-broadcast android:name="com.systemui.navigationbar.hide" /><applicationandroid:name=".SystemUIApplication"android:persistent="true"

+                mStatusBarWindowController.setBarVisibility(View.VISIBLE);}}};

frameworks/base/packages/SystemUI/src/com/android/systemui/statusbar/phone/StatusBarWindowController.java

+    /**
+     * Sets the visibility of the status bar window.
+     * 设置状态栏的可见性
+     */
+    public void setBarVisibility(int visibility) {
+        mStatusBarWindowView.setVisibility(visibility);
+    }

frameworks/base/packages/SystemUI/src/com/android/systemui/shade/NotificationPanelViewController.java 修改三个方法此类主要是锁屏后状态栏处理

+             int barState = getBarState();
+             //根据系统设置参数控制锁平后面板是否显示 ，禁止对状态栏布局设置
+             boolean statusBarDisplay=SystemProperties.getBoolean(CentralSurfacesImpl.SYS_PROPERTY_STATUS_BAR, false);
+             //非锁屏的状态栏状态栏下拉面板隐藏处理
+              if (!statusBarDisplay && barState!=KEYGUARD) {

3、修改Settings APP

+    <string name="ctrl_statusbar">状态栏</string>
+    <string name="ctrl_navigationbar">导航栏</string></resources>

android/packages/apps/Settings/res/values/strings.xml

+   <!--状态栏和导航栏开关设置 -->

}

4、设置-->显示菜单里的效果如下图
