HarmonyOS鸿蒙Next中请问怎么实现轮播图，但是显示三个，第一个会缩放放大，其他的还是不变

推荐使用Swiper组件：

// xxx.ets
class MyDataSource implements IDataSource {
  private list: number[] = [];
  constructor(list: number[]) {
    this.list = list;
  }
  totalCount(): number {
    return this.list.length;
  }
  getData(index: number): number {
    return this.list[index];
  }
  registerDataChangeListener(listener: DataChangeListener): void {
  }
  unregisterDataChangeListener() {
  }
}
@Entry
@Component
struct SwiperExample {
  private swiperController: SwiperController = new SwiperController();
  private data: MyDataSource = new MyDataSource([]);
  aboutToAppear(): void {
    let list: number[] = [];
    for (let i = 1; i <= 10; i++) {
      list.push(i);
    }
    this.data = new MyDataSource(list);
  }
  build() {
    Column({ space: 5 }) {
      Swiper(this.swiperController) {
        LazyForEach(this.data, (item: string) => {
          Text(item.toString())
            .width('90%')
            .height(160)
            .backgroundColor(0xAFEEEE)
            .textAlign(TextAlign.Center)
            .fontSize(30)
        }, (item: string) => item)
      }
      .cachedCount(2)
      .index(1)
      .autoPlay(true)
      .interval(4000)

      .indicator( // 设置圆点导航点样式
        new DotIndicator()
          .itemWidth(15)
          .itemHeight(15)

      }, false)
      .curve(Curve.Linear)
      .onChange((index: number) => {
        console.info(index.toString());
      })
      .onScrollStateChanged((event: ScrollState) => {
        console.info("event: " + event);
      })

      })
