说明

本修改主要针对 Android 16（API 36）AOSP 源码中的 SystemUI 模块。

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。

2. 修改PhoneStatusBarPolicy.java

路径：frameworks/base/packages/SystemUI/src/com/android/systemui/statusbar/phone/PhoneStatusBarPolicy.java

方法：updateBluetooth()

修改前

privatefinalvoidupdateBluetooth(){inticonId=R.drawable.stat_sys_data_bluetooth_connected;StringcontentDescription=mResources.getString(R.string.accessibility_quick_settings_bluetooth_on);booleanbluetoothVisible=false;if(mBluetooth!=null){// Bug 2687381, The Bluetooth icon is not displayed normally.Log.d(TAG,"updateBluetooth(), mIsActive:"+mBluetooth.isBluetoothAudioActive());if(mBluetooth.isBluetoothConnected()&&(mBluetooth.isBluetoothAudioActive()||!mBluetooth.isBluetoothAudioProfileOnly())){contentDescription=mResources.getString(R.string.accessibility_bluetooth_connected);bluetoothVisible=mBluetooth.isBluetoothEnabled();}}// ...}

修改后

privatefinalvoidupdateBluetooth(){// Create by yeruilai 2026-6-6 19:54:14 Display Bluetooth icon when open// int iconId = R.drawable.stat_sys_data_bluetooth_connected;inticonId=R.drawable.stat_sys_data_bluetooth;StringcontentDescription=mResources.getString(R.string.accessibility_quick_settings_bluetooth_on);booleanbluetoothVisible=false;if(mBluetooth!=null){// Bug 2687381, The Bluetooth icon is not displayed normally.Log.d(TAG,"updateBluetooth(), mIsActive:"+mBluetooth.isBluetoothAudioActive());// Create by yeruilai 2026-6-6 19:54:14 Display Bluetooth icon when openbluetoothVisible=mBluetooth.isBluetoothEnabled();if(mBluetooth.isBluetoothConnected()&&(mBluetooth.isBluetoothAudioActive()||!mBluetooth.isBluetoothAudioProfileOnly())){contentDescription=mResources.getString(R.string.accessibility_bluetooth_connected);bluetoothVisible=mBluetooth.isBluetoothEnabled();// Create by yeruilai 2026-6-6 19:54:14 Display Bluetooth icon when openiconId=R.drawable.stat_sys_data_bluetooth_connected;}}// ...}

修改点

private final void updateBluetooth() { - int iconId = R.drawable.stat_sys_data_bluetooth_connected; + // Create by yeruilai 2026-6-6 19:54:14 Display Bluetooth icon when open + // int iconId = R.drawable.stat_sys_data_bluetooth_connected; + int iconId = R.drawable.stat_sys_data_bluetooth; String contentDescription = mResources.getString(R.string.accessibility_quick_settings_bluetooth_on); boolean bluetoothVisible = false; if (mBluetooth != null) { // Bug 2687381, The Bluetooth icon is not displayed normally. Log.d(TAG, "updateBluetooth(), mIsActive:" + mBluetooth.isBluetoothAudioActive()); + // Create by yeruilai 2026-6-6 19:54:14 Display Bluetooth icon when open + bluetoothVisible = mBluetooth.isBluetoothEnabled(); if (mBluetooth.isBluetoothConnected() && (mBluetooth.isBluetoothAudioActive() || !mBluetooth.isBluetoothAudioProfileOnly())) { contentDescription = mResources.getString( R.string.accessibility_bluetooth_connected); bluetoothVisible = mBluetooth.isBluetoothEnabled(); + // Create by yeruilai 2026-6-6 19:54:14 Display Bluetooth icon when open + iconId = R.drawable.stat_sys_data_bluetooth_connected; } }
