RK3576 Android14 状态栏和导航栏增加显示控制功能

article 2025/1/17 13:49:59

  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" />
    
    <application
        android:name=".SystemUIApplication"
        android:persistent="true"

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

+    }

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

import android.os.SystemProperties;

                }
            }

+             int barState = getBarState();

            mQsController.setShadeExpansion(mExpandedHeight, mExpandedFraction);
            mExpansionDragDownAmountPx = h;
            mAmbientState.setExpansionFraction(mExpandedFraction);

//====================================================
   public final class TouchHandler implements View.OnTouchListener, Gefingerpoken {

        /** @see ViewGroup#onInterceptTouchEvent(MotionEvent) */
        @Override
        public boolean onInterceptTouchEvent(MotionEvent event) {
            ..............................
            if (!mQsController.shouldQuickSettingsIntercept(mDownX, mDownY, 0)

           .......................................

3、修改Settings  APP

android/packages/apps/Settings/res/values-zh-rCN/strings.xml

+    <!--状态栏和导航栏开关设置 -->

  </resources>

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

+   <!--状态栏和导航栏开关设置 -->
+    <string name="ctrl_statusbar">StatusBar</string>
+    <string name="ctrl_navigationbar">NavigationBar</string>
</resources>

android/packages/apps/Settings/res/xml/display_settings.xml

        settings:userRestriction="no_config_brightness">
        <intent android:action="com.android.intent.action.SHOW_BRIGHTNESS_DIALOG" />

+    <SwitchPreference
+                android:key="ctrl_statusbar"

+    <SwitchPreference
+                android:key="ctrl_navigationbar"
