HarmonyOS Swiper设置displayCount显示多个indicator个数还是所有item个数？

Swiper(this.swiperController) {  
  LazyForEach(this.data, (item: string) => {  
    Flex() {  
      Image($r('app.media.startIcon'))  
      Image($r('app.media.startIcon'))  
      Image($r('app.media.startIcon'))  
    }.height('20%')  
  }, (item: string) => item)  
}
