HarmonyOS 拖拽排序以及控件平移效果是否有工具类可以用，当前控件数据数量上限无法满足

动画效果可以参考以下demo：

@Entry
@Component
struct AnimationPage {
  @Provide desX: number = 0;
  @Provide desY: number = 0;

  @Builder
  TabBar(index: number) {
    Column() {
      Image($r("app.media.icon"))
        .width(38)
        .height(38)
      Text(index == 1 ? "分类" : index.toString())
    }
    .onAreaChange((oldValue: Area, newValue: Area) => {
      if (index == 1) {
        console.log("onAreaChange========= newValue:" + JSON.stringify(newValue))
        this.desX = newValue.globalPosition.x as number
        this.desY = newValue.globalPosition.y as number
      }
    })
  }

  build() {
    Column() {
      Category()
      Column() {
        Image($r("app.media.icon"))
          .width(38)
          .height(38)
      }
      .onAreaChange((oldValue: Area, newValue: Area) => {
        console.log("onAreaChange========= newValue:" + JSON.stringify(newValue))
        this.desX = newValue.globalPosition.x as number
        this.desY = newValue.globalPosition.y as number
      })
    }
    .width("100%")
    .height("100%")
  }
}

@Component
struct Category {

  @State dataList:number[] = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20]

  build() {
    Column() {
      Flex({direction:FlexDirection.Row, justifyContent: FlexAlign.SpaceBetween, wrap: FlexWrap.Wrap}) {
        ForEach(this.dataList, (item:number) => {
          ListItemComponent()
        })
      }
      .width('100%')

      .id("test")
      .onClick(() => {
        this.startAnimation();
      })
      .onAreaChange((oldValue:Area, newValue:Area) => {

        console.log("onAreaChage==========" + JSON.stringify(newValue))
