PullToRefresh 去掉下拉刷新完整代码：

import { HttpGet } from '../common/HttpUtil'
import { NewsModel } from '../models/NewModel'
import { PullToRefresh, PullToRefreshConfigurator } from '@ohos/pulltorefresh'

@Entry
@Component
struct Index {
  //scroller需要在list里面绑定还需要在PullToRefresh绑定
  private scroller: Scroller = new Scroller();
  @State newsList: NewsModel[] = []
  @State hasMore: boolean = true
  @State page: number = 1
  pullToRefreshConfigurator?:PullToRefreshConfigurator

  aboutToAppear() {
    this.getNewsList()
    this.pullToRefreshConfigurator=new PullToRefreshConfigurator()
    this.pullToRefreshConfigurator.setHasRefresh(false)
  }

  //上拉分页
  getNewsList(resolve?: (value: string | PromiseLike<string>) => void) {
    let apiUri: string = `https://www.phonegap100.com/appapi.php?a=getPortalList&catid=20&page=${this.page}`
    console.log(apiUri)
    HttpGet(apiUri).then((response) => {
      // console.log(JSON.stringify(response))
      if (response.success) {
        let data: string = JSON.stringify(response.result)
        let result: NewsModel[] = JSON.parse(data)
        //判断有没有数据
        if (result.length < 20) {
          this.hasMore = false
        }
        this.newsList = this.newsList.concat(result) //拼接数据   [1,2,3] 和[4,5]拼接以后得到的数据就是[1,2,3,4,5]
        this.page++
        if (resolve) {
          resolve("")
        }
      }
    })
  }

  //下拉刷新
  getRefreshList(resolve?: (value: string | PromiseLike<string>) => void) {
    let apiUri: string = `https://www.phonegap100.com/appapi.php?a=getPortalList&catid=20&page=1`
    HttpGet(apiUri).then((response) => {

        let result: NewsModel[] = JSON.parse(data)

        this.page=2
        this.hasMore=true;
        if (resolve) {
