HarmonyOS鸿蒙Next中LazyForEach滑动到数据第一条的时候数据list没错，但是页面显示列如下标1的数据显示在了下标0

class MyDataSource implements IDataSource {
  private dataArray: string[] = []
  private listener: DataChangeListener | undefined

  public totalCount(): number {
    return this.dataArray.length
  }

  public getData(index: number): string {
    return this.dataArray[index]
  }

    this.dataArray.push(data)
  }

  public reloadListener(): void {
    this.listener?.onDataReloaded()

    this.listener = listener

  public unregisterDataChangeListener(listener: DataChangeListener): void {
    this.listener = undefined

用简易的数据，好像没有出现楼主的问题，建议查看打印一下id是否存在重复（keyGenerator 生成的键）标识组件

这个组件的简解我也写过：https://developer.huawei.com/consumer/cn/blog//topic/03197384103127220
