HarmonyOS怎么通过点击事件触发显示swipeAction的控件显示？

@Observed  
class showData2 {  
  num: number  
  offsetX: number  
  isDelShow: boolean  
  constructor(num: number, offsetX: number, isDelShow: boolean) {  
    this.num = num  
    this.offsetX = offsetX  
    this.isDelShow = isDelShow  
  }  
}  
@Observed  
class showArray extends Array<showData2> {  
}
// xxx.ets  
@Entry

    for (let i = 0; i < 50; i++) {  
      this.arr.push(new showData2(i, 0, false))  
    }  
  }
