导出鸿蒙包后用DevEco Studio打开,找到WindowUtils.ets,找到setScreenOn方法

setScreenOn(value: boolean) {
    let windowClass: window.Window = this.getMainWindow();
    // only kNeverSleep & kSystemSetting are supported like other platforms
    windowClass.setWindowKeepScreenOn(true); -- 此处改为写死的true,或者可以找到上层调用修改传入值
  }
