HarmonyOS Swiper+ForEach使用问题

Swiper(this.swiperController) {  
      LazyForEach(this.calendarDataSource, (item: CalendarModelList) => {  
        Column() {  
          //日期列表  
          List() {  
            ForEach(this.changeData(item), (item: CalendarModelList) => {  
              ListItem() {  
                CalendarListItem({ dateList: item})  
              }  
            })  
          }  
          Stack(){  
            //显示图例  
            CalendarState()  
            //显示农历提示语  
            CalendarTip().visibility(this.isShowTip && !this.selectCalendarModel.isPregnancy() ? Visibility.Visible : Visibility.None)  
          }  
          //孕周显示  
          CalendarPregnantData()  
        }.padding({ bottom: 5 })  
      },  
        (item: CalendarModel[], index: number) => {  
          return JSON.stringify(item)}  
      )  
    }  
    .indicator(false)  
    .loop(false)  
    .cachedCount(1)  
    .index(this.currentIndex)

this.calendarDataSource.addData(0,calendarModeList)  this.currentIndex = 1
