说明本修改主要针对 Android 16API 36AOSP 源码中的 SystemUI 模块。项目内容适用版本Android 16API 36涉及模块frameworks/base/packages/SystemUI修改类PhoneStatusBarPolicy修改方法updateBluetooth()在 Android 16 原生 SystemUI 中PhoneStatusBarPolicy.updateBluetooth()默认仅在蓝牙已连接且满足音频 Profile 条件时才显示状态栏图标。用户仅打开蓝牙开关、尚未连接设备时状态栏不会出现蓝牙图标与快捷设置中蓝牙已开启的状态不一致。本次修改在 Android 16 上实现蓝牙开启即显示stat_sys_data_bluetooth图标新增资源蓝牙已连接时切换为stat_sys_data_bluetooth_connected图标蓝牙关闭时隐藏图标若移植到其他 Android 版本需确认对应分支中PhoneStatusBarPolicy.java路径及updateBluetooth()实现是否一致资源命名是否相同。修改文件frameworks/base/packages/SystemUI/res/drawable/stat_sys_data_bluetooth.xml (新增) frameworks/base/packages/SystemUI/src/com/android/systemui/statusbar/phone/PhoneStatusBarPolicy.java (修改)1. 新增stat_sys_data_bluetooth.xml路径frameworks/base/packages/SystemUI/res/drawable/stat_sys_data_bluetooth.xml!-- Copyright (C) 2017 The Android Open Source Project Licensed under the Apache License, Version 2.0 (the License); you may not use this file except in compliance with the License.
