HarmonyOS 鸿蒙Next 如何在响应Swiper的滑动事件时不触发子组件的Down、up等事件，在不滑动时才响应子组件的Down、up等事件

Swiper() {
  ForEach(this.operateList, (section: DeviceOperateSection) => {
    Grid() {
      this.FunctionGrid(section.items);
    }
  }, (item: DeviceOperateSection) => JSON.stringify(item))
}
.indicator(false)
.loop(false)
.width(“100%”)
.height(“100vp”)
.backgroundColor($r(‘app.color.whiteColor’))
.onChange((index) => {
  this.index = index
})

@Builder
FunctionGrid(data: DeviceOperateItem[]) {
  ForEach(data, (item: DeviceOperateItem) => {
    GridItem() {
      Column({space: “10vp”}) {
        Image(this.currentOperateItemType === item.type ? item.selectImg : item.img)
            .objectFit(ImageFit.Contain)
            .height(“35vp”)
            .width(“35vp”)
          Text(item.title)
            .fontSize(“12vp”)
            .fontColor(this.currentOperateItemType === item.type ? $r(‘app.color.primaryColor’) :$r(‘app.color.blackColor’))
      }
      .alignItems(HorizontalAlign.Center)
      .justifyContent(FlexAlign.Center)
      .width(“100%”)
      .height(“100%”)
      .onTouch((event: TouchEvent) => {
        if (event.type === TouchType.Down) {
          this.currentOperateItemType = item.type
        } else if (event.type === TouchType.Up) {
