#鸿蒙通关秘籍#如何在HarmonyOS Next中自定义轮播图的切换动画？

可以通过customContentTransition自定义轮播图的切换动画。利用SwiperContentAnimatedTransition和SwiperContentTransitionProxy属性进行调整。在切换过程中position属性会提供页面相对于选中页面的移动比例，利用这个属性可以实现缩放效果：

@Entry
@Component
struct CustomTransitionSwiper {
  controller: SwiperController = new SwiperController()
  imageList: string[] = [
    'https://example.com/image1.jpg',
    'https://example.com/image2.jpg',
    'https://example.com/image3.jpg'
  ]

  build() {
    Column() {
      Swiper(this.controller) {
        ForEach(this.imageList, (item: string) => {
          Image(item).height(300).borderRadius(10)
        })
      }
      .width('100%')
      .autoPlay(false)
      .customContentTransition({
        timeout: 1000,
        transition: (proxy: SwiperContentTransitionProxy) => {
          let scale = 1 - Math.abs(proxy.position) * 0.2
          console.log(`Scale for index ${proxy.index}: ${scale}`)
          // Set scale value to the targeted UI elements
        }
      })
    }
    .width('100%')
    .height('100%')
  }
}
