Android 12.0 开启蓝牙状态栏即显示蓝牙图标

最近收到客户反馈想要在开启蓝牙时状态栏就能显示出蓝牙图标，我们系统默认是蓝牙连接上设备后状态栏才显示出蓝牙图标，具体修改参照如下：

/vendor/mediatek/proprietary/packages/apps/SystemUI/src/com/android/systemui/statusbar/phone/PhoneStatusBarPolicy.java

    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) {
+            if(mBluetooth.isBluetoothEnabled()) {
+                contentDescription = mResources.getString(R.string.accessibility_quick_settings_bluetooth_on);
+                bluetoothVisible = mBluetooth.isBluetoothEnabled();
+                iconId = R.drawable.ic_qs_bluetooth_on;
+            }if (mBluetooth.isBluetoothConnected()&& (mBluetooth.isBluetoothAudioActive()|| !mBluetooth.isBluetoothAudioProfileOnly())) {
+                iconId = R.drawable.stat_sys_data_bluetooth_connected;contentDescription = mResources.getString(R.string.accessibility_bluetooth_connected);bluetoothVisible = mBluetooth.isBluetoothEnabled();}}

重新编译验证，修改生效，开启蓝牙时状态栏即显示蓝牙图标
