参考demo：

@Entry
@Component
struct ListItemExample2 {
  @State arr: number[] = [0, 1, 2, 3, 4]
  @State enterEndDeleteAreaString: string = "not enterEndDeleteArea"
  @State exitEndDeleteAreaString: string = "not exitEndDeleteArea"
  @State isShow:boolean = true;

  @Builder itemEnd() {
    Row() {
      Button("Delete").margin("4vp")
      Button("Set").margin("4vp")
    }.padding("4vp").justifyContent(FlexAlign.SpaceEvenly)
  }

  build() {
    Column() {
      Button("点击").onClick(()=>{
        this.isShow=!this.isShow
        console.log(this.isShow+"111111111")
      })
      List({ space: 10 }) {
        ForEach(this.arr, (item: number) => {
          ListItem() {
            Text("item" + item)
              .width('100%')
              .height(100)
              .fontSize(16)
              .textAlign(TextAlign.Center)
              .borderRadius(10)
              .backgroundColor(0xFFFFFF)
          }
          .transition({ type: TransitionType.Delete, opacity: 0 })
          .swipeAction({
            end: this.isShow?{
              builder: () => { this.itemEnd() },
              onAction: () => {
                animateTo({ duration: 1000 }, () => {
                  let index = this.arr.indexOf(item)
                  this.arr.splice(index, 1)
                })
              },
              actionAreaDistance: 56,
              onEnterActionArea: () => {
                this.enterEndDeleteAreaString = "enterEndDeleteArea"
                this.exitEndDeleteAreaString = "not exitEndDeleteArea"
              },
              onExitActionArea: () => {
                this.enterEndDeleteAreaString = "not enterEndDeleteArea"
                this.exitEndDeleteAreaString = "exitEndDeleteArea"
              }
            }:undefined
          })
        }, (item: string) => item)
      }
      Text(this.enterEndDeleteAreaString).fontSize(20)
      Text(this.exitEndDeleteAreaString).fontSize(20)
    }
    .padding(10)
    .backgroundColor(0xDCDCDC)
    .width('100%')
    .height('100%')
  }
