Android16 蓝牙打开时，状态栏显示蓝牙图标

说明

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

项目	内容
适用版本	Android 16（API 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。

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

private final void updateBluetooth() {
    int iconId = R.drawable.stat_sys_data_bluetooth_connected;
    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());
        if (mBluetooth.isBluetoothConnected()
                && (mBluetooth.isBluetoothAudioActive()
                || !mBluetooth.isBluetoothAudioProfileOnly())) {
            contentDescription = mResources.getString(
                    R.string.accessibility_bluetooth_connected);
            bluetoothVisible = mBluetooth.isBluetoothEnabled();
        }
    }
    // ...
}

修改后

private final void updateBluetooth() {
    // 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;
        }
    }
    // ...
}

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;
         }
     }
