@Entry
@Component
struct PageList {
  @State arr: string[] = ["0", "1", "2", "3", "4", "5", "6", "7", "8", "9", "10", "11", "12", "13", "14", "15", "16", "17", "18", "19"]


  getmorePage(){
    let begini:number =this.arr.length
    console.info('begin' + begini)
    for(let i = begini;i < (begini+10); i++ ){
      this.arr.push(i.toString())
    }
  }

  build() {
    Column() {
      List({ space: 20, initialIndex: 0 }) {
        ForEach(this.arr, (item) => {
          ListItem() {
            Text('' + item)
              .width('100%').height(100).fontSize(16)
              .textAlign(TextAlign.Center).borderRadius(10).backgroundColor(0xFFFFFF)
          }
        }, item => item)
      }
      .listDirection(Axis.Vertical) // 排列方向
      .divider({ strokeWidth: 2, color: 0xFFFFFF, startMargin: 20, endMargin: 20 }) // 每行之间的分界线
      .edgeEffect(EdgeEffect.Spring) // 滑动到边缘无效果
      .onScrollIndex((firstIndex: number, lastIndex: number) => {
        console.info('first' + firstIndex)
        console.info('last' + lastIndex)
        this.getmorePage()
      })
      .width('90%')
    }
    .width('100%')
    .height('100%')
    .backgroundColor(0xDCDCDC)
    .padding({ top: 5 })
  }
