QS菜单栏的安全与隐私Tile组件(GMS中的)加载逻辑

/frameworks/base/packages/SystemUI/src/com/android/systemui/statusbar/phone/AutoTileManager.java

1.开机下拉QS菜单栏得安全与隐私Tile组件（mSafetySpec ）初始化好了

java 复制代码

public AutoTileManager(Context context, AutoAddTracker.Builder autoAddTrackerBuilder,
            QSHost host,
            @Background Handler handler,
            SecureSettings secureSettings,
            HotspotController hotspotController,
            DataSaverController dataSaverController,
            ManagedProfileController managedProfileController,
            NightDisplayListenerModule.Builder nightDisplayListenerBuilder,
            CastController castController,
            ReduceBrightColorsController reduceBrightColorsController,
            DeviceControlsController deviceControlsController,
            WalletController walletController,
            SafetyController safetyController,
            @Named(RBC_AVAILABLE) boolean isReduceBrightColorsAvailable) {
        mContext = context;
        mHost = host;
        mSecureSettings = secureSettings;
        mCurrentUser = mHost.getUserContext().getUser();
        mAutoTracker = autoAddTrackerBuilder.setUserId(mCurrentUser.getIdentifier()).build();
        mHandler = handler;
        mHotspotController = hotspotController;
        mDataSaverController = dataSaverController;
        mManagedProfileController = managedProfileController;
        mNightDisplayListenerBuilder = nightDisplayListenerBuilder;
        mCastController = castController;
        mReduceBrightColorsController = reduceBrightColorsController;
        mIsReduceBrightColorsAvailable = isReduceBrightColorsAvailable;
        mDeviceControlsController = deviceControlsController;
        mWalletController = walletController;
        mSafetyController = safetyController;
        String safetySpecClass;
        try {
            safetySpecClass =
                    context.getResources().getString(R.string.safety_quick_settings_tile_class);
            if (safetySpecClass.length() == 0) {
                safetySpecClass = null;
            }
        } catch (Resources.NotFoundException | NullPointerException e) {
            safetySpecClass = null;
        }
        mSafetySpec = safetySpecClass != null ? CustomTile.toSpec(new ComponentName(mContext
                .getPackageManager().getPermissionControllerPackageName(), safetySpecClass)) : null;
    }

2.检查mSafetySpec是否在pms中存在（这个是谷歌的组件，得预置了GMS得才存在），如果存在就开始init把mSafetySpec加载进QS面板

java 复制代码

 protected void startControllersAndSettingsListeners() {
        if (!mAutoTracker.isAdded(HOTSPOT)) {
            mHotspotController.addCallback(mHotspotCallback);
        }
        if (!mAutoTracker.isAdded(SAVER)) {
            mDataSaverController.addCallback(mDataSaverListener);
        }
        mManagedProfileController.addCallback(mProfileCallback);

        mNightDisplayListener = mNightDisplayListenerBuilder
                .setUser(mCurrentUser.getIdentifier())
                .build();
        if (!mAutoTracker.isAdded(NIGHT)
                && ColorDisplayManager.isNightDisplayAvailable(mContext)) {
            mNightDisplayListener.setCallback(mNightDisplayCallback);
        }
        if (!mAutoTracker.isAdded(CAST)) {
            mCastController.addCallback(mCastCallback);
        }
        if (!mAutoTracker.isAdded(BRIGHTNESS) && mIsReduceBrightColorsAvailable) {
            mReduceBrightColorsController.addCallback(mReduceBrightColorsCallback);
        }
        // We always want this callback, because if the feature stops being supported,
        // we want to remove the tile from AutoAddTracker. That way it will be re-added when the
        // feature is reenabled (similar to work tile).
        mDeviceControlsController.setCallback(mDeviceControlsCallback);
        if (!mAutoTracker.isAdded(WALLET)) {
            initWalletController();
        }
        if (mSafetySpec != null) {
            if (!mAutoTracker.isAdded(mSafetySpec)) {
                initSafetyTile();
            }
            mSafetyController.addCallback(mSafetyCallback);
        }

        int settingsN = mAutoAddSettingList.size();
        for (int i = 0; i < settingsN; i++) {
            if (!mAutoTracker.isAdded(mAutoAddSettingList.get(i).mSpec)) {
                mAutoAddSettingList.get(i).setListening(true);
            }
        }
    }

3.开始往mHost中添加mSafetySpec组件Tile

java 复制代码

    private void initSafetyTile() {
        if (mSafetySpec == null || mAutoTracker.isAdded(mSafetySpec)) {
            return;
        }
        mHost.addTile(CustomTile.getComponentFromSpec(mSafetySpec), true);
        mAutoTracker.setTileAdded(mSafetySpec);
    }
