如题：HarmonyOS 如何修改下拉刷新时里面的icon，将其替换成文字？

Answer 1

下面是隐藏icon&显示文字的demo：

@Entry
@Component
struct RefreshExample {
  @State isRefreshing: boolean = false
  @State arr: String[] = ['0', '1', '2', '3', '4','5','6','7','8','9','10']
  @Builder
  customRefreshComponent()
  {
    Stack()
    {
      Row()
      {
        // 隐藏icon
        // LoadingProgress().height(32)
        Text("正在刷新...").fontSize(16).margin({left:20})
      }
      .alignItems(VerticalAlign.Center)
    }.width("100%").align(Alignment.Center)
  }

  build() {
    Column() {
      Refresh({ refreshing: $$this.isRefreshing,builder:this.customRefreshComponent()}) {
        List() {
          ForEach(this.arr, (item: string) => {
            ListItem() {
              Text('' + item)
                .width('100%').height(100).fontSize(16)
                .textAlign(TextAlign.Center).borderRadius(10).backgroundColor(0xFFFFFF)
            }
          }, (item: string) => item)
        }
        .onScrollIndex((first: number) => {
          console.info(first.toString())
        })
        .width('100%')
        .height('100%')
        .divider({strokeWidth:1,color:Color.Yellow,startMargin:10,endMargin:10})
        .scrollBar(BarState.Off)
      }

      .onStateChange((refreshStatus: RefreshStatus) => {
        console.info('Refresh onStatueChange state is ' + refreshStatus)
      })
      .onRefreshing(() => {
        setTimeout(() => {
          this.isRefreshing = false
        }, 2000)
        console.log('onRefreshing test')
      })
      .backgroundColor(0x89CFF0)
    }
  }
}
