@Component
struct Index {@Staterefreshing: boolean = false@Statelist: number[] = Array(20).fill(Date.now())@Buildercontent(){Stack(){Row(){LoadingProgress().height(32)Text('正在刷新...').fontSize(16).margin({left:20})}.alignItems(VerticalAlign.Center)}.align(Alignment.Center)}build() {Column(){Refresh({ refreshing: $$this.refreshing, builder: this.content() }){List(){ForEach(this.list, (item: string)=>{ListItem(){Row(){Text(item.toString())}.justifyContent(FlexAlign.Center).width('100%').padding(20)}})}.divider({strokeWidth: 1,color: Color.Yellow,startMargin: 10,endMargin: 10})}.onRefreshing(()=>{setTimeout(()=>{this.list = Array(20).fill(Date.now())this.refreshing = falsepromptAction.showToast({message:'刷新成功'})},1000)})}.height('100%').width('100%')}
