android9.0 修改状态栏图标的顺序

原理

com.android.systemui.statusbar.phone/StatusBarIconControllerImpl.java类的构造方法中读取
com.android.internal.R.array.config_statusBarIcons，按照此数组的顺序排序，如果需要修改顺序，则需要修改此文件。

 public StatusBarIconControllerImpl(Context context) {
        super(context.getResources().getStringArray(
                com.android.internal.R.array.config_statusBarIcons), context);
        Dependency.get(ConfigurationController.class).addCallback(this);

        mContext = context;

        loadDimens();

        SysUiServiceProvider.getComponent(context, CommandQueue.class)
                .addCallbacks(this);
        Dependency.get(TunerService.class).addTunable(this, ICON_BLACKLIST);

    }
