为了在 Android 14 的下拉菜单中增加自动亮度调节按钮，可以按照以下步骤进行代码修改。

1. 添加图标资源

在 SystemUI 资源文件夹中添加自动亮度图标：

文件路径：

frameworks/base/packages/SystemUI/res/drawable/ic_settings_display_white.xml

文件内容：

<vector xmlns:android="http://schemas.android.com/apk/res/android"android:width="24dp"android:height="24dp"android:viewportWidth="24.0"android:viewportHeight="24.0"><pathandroid:pathData="M20.31,9V4.31H15.62L12.31,1L9,4.31H4.31V9L1,12.31L4.31,15.62V20.31H9L12.31,23.62L15.62,20.31H20.31V15.62L23.62,12.31L20.31,9ZM18.31,14.79V18.31H14.79L12.31,20.79L9.83,18.31H6.31V14.79L3.83,12.31L6.31,9.83V6.31H9.83L12.31,3.83L14.79,6.31H18.31V9.83L20.79,12.31L18.31,14.79ZM17.31,12.31C17.31,15.07 15.07,17.31 12.31,17.31V7.31C15.07,7.31 17.31,9.55 17.31,12.31Z"android:fillType="evenOdd"android:fillColor="?android:attr/colorPrimary"/>
</vector>

2. 更新字符串资源

在 strings.xml 中添加自动亮度调节的标题：

文件路径：

frameworks/base/packages/SystemUI/res/values/strings.xml
frameworks/base/packages/SystemUI/res/values-zh-rCN/strings.xml

在 strings.xml 中新增：

<string name="autobrightness_title">AutoBrightness</string>

在 strings.xml (zh-rCN) 中新增：

<string name="autobrightness_title">自动亮度调节</string>

3. 配置快速设置中的自动亮度 Tile

在 config.xml 中将自动亮度添加到快速设置面板的默认项目中：

文件路径：

frameworks/base/packages/SystemUI/res/values/config.xml

修改内容：

<string name="quick_settings_tiles_stock" translatable="false">internet,bt,flashlight,dnd,alarm,airplane,controls,wallet,rotation,battery,autobrightness,superbattery,cast,screenrecord,mictoggle,cameratoggle,location,hotspot,inversion,saver,dark,work,night,reverse,reduce_brightness,qr_code_scanner,color_correction,dream,font_scaling
</string>

4. 创建 AutoBrightnessTile 类

创建 AutoBrightnessTile.java 实现自动亮度 Tile 的逻辑：

文件路径：

frameworks/base/packages/SystemUI/src/com/android/systemui/qs/tiles/AutoBrightnessTile.java

文件内容：

package com.android.systemui.qs.tiles;import android.content.ContentResolver;
import android.content.Intent;
import android.provider.Settings;
import android.service.quicksettings.Tile;
import android.util.Log;
import android.view.View;
import androidx.annotation.Nullable;
import com.android.systemui.R;
import com.android.systemui.qs.QSHost;
import com.android.systemui.qs.tileimpl.QSTileImpl;
import javax.inject.Inject;public class AutoBrightnessTile extends QSTileImpl<BooleanState> {public static final String TILE_SPEC = "autobrightness";@Injectpublic AutoBrightnessTile(QSHost host) {super(host);}@Overridepublic BooleanState newTileState() {BooleanState state = new BooleanState();state.handlesLongClick = true;return state;}@Overrideprotected void handleClick(@Nullable View view) {Log.i("AutoBrightnessTile", "Clicked on AutoBrightness tile");toggleBrightnessMode();refreshState();}private void toggleBrightnessMode() {ContentResolver resolver = mContext.getContentResolver();int currentMode = Settings.System.getInt(resolver, Settings.System.SCREEN_BRIGHTNESS_MODE, MODE_MANUAL);int newMode = (currentMode == MODE_MANUAL) ? MODE_AUTOMATIC : MODE_MANUAL;Settings.System.putInt(resolver, Settings.System.SCREEN_BRIGHTNESS_MODE, newMode);}private boolean isAutoBrightnessEnabled() {ContentResolver resolver = mContext.getContentResolver();int mode = Settings.System.getInt(resolver, Settings.System.SCREEN_BRIGHTNESS_MODE, MODE_MANUAL);return mode == MODE_AUTOMATIC;}@Overridepublic CharSequence getTileLabel() {return mContext.getString(R.string.autobrightness_title);}@Overrideprotected void handleUpdateState(BooleanState state, Object arg) {state.label = mContext.getString(R.string.autobrightness_title);state.value = isAutoBrightnessEnabled();state.contentDescription = state.label;state.state = state.value ? Tile.STATE_ACTIVE : Tile.STATE_INACTIVE;state.icon = ResourceIcon.get(R.drawable.ic_settings_display_white);}
}

5. 在 PolicyModule 中注册 Tile

确保 AutoBrightnessTile 注册在 PolicyModule 中：

文件路径：

frameworks/base/packages/SystemUI/src/com/android/systemui/statusbar/policy/PolicyModule.kt

修改内容：

--- a/frameworks/base/packages/SystemUI/src/com/android/systemui/statusbar/policy/PolicyModule.kt
+++ b/frameworks/base/packages/SystemUI/src/com/android/systemui/statusbar/policy/PolicyModule.kt

+    @Binds
+    @IntoMap
+    @StringKey(AutoBrightnessTile.TILE_SPEC)
+    fun bindAutoBrightnessTile(autobrightnessTile: AutoBrightnessTile): QSTileImpl<*>

6. 配置默认快速设置

在特定的 config.xml 覆盖文件中确保默认启用自动亮度：

文件路径：

vendor/partner_gms/unisoc_conf/overlay/gms_overlay_unisoc/frameworks/base/packages/SystemUI/res/values/config.xml

修改内容：

<string name="quick_settings_tiles_default" translatable="false">internet,bt,dnd,flashlight,rotation,battery,airplane,autobrightness,night,qr_code_scanner,screenrecord,cast,mictoggle,cameratoggle
</string>

以上步骤完成后，重新编译并安装系统镜像。此改动将会在 Android 14 的 SPRD 下拉菜单中增加自动亮度调节的快捷开关。
