HarmonyOS Refresh和页面转场动画demo

示例如下：

//1、RefreshPage.ets
import { router } from '@kit.ArkUI'

@Entry
@Component
struct RefreshPage {
  @State isRefreshing: boolean = false
  @State arr: String[] = ['0', '1', '2', '3', '4', '5', '6', '7', '8', '9', '10']

  pageTransition() {
    PageTransitionExit({ type: RouteType.Push, duration: 1000 })
      .slide(SlideEffect.Bottom)
  }

  @Builder
  customRefreshComponent() {
    Row() {
      Column() {
        LoadingProgress().height(40)
        Text("正在刷新...").height(20)
      }
      .width('100%')
    }.align(Alignment.Center).borderStyle(BorderStyle.Solid).height(100)
  }

  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)
        }
        .width('100%')
        .height('100%')
        .divider({
          strokeWidth: 1,
          color: Color.Yellow,
          startMargin: 10,
          endMargin: 10
        })
        .scrollBar(BarState.Off)
      }
      .onStateChange((status: RefreshStatus) => {
        if (status == RefreshStatus.Done) {
          router.pushUrl({ url: 'pages/SPage' })
        }
      })
      .onRefreshing(() => {
        setTimeout(() => {
          this.isRefreshing = false
        }, 2000)
      })
      .backgroundColor(0x89CFF0)
    }
  }
}

//2、FPage.ets
@Entry
@Component
struct FPage {
  @State message: string = 'Hello World';

  pageTransition() {
    PageTransitionEnter({ type: RouteType.Push, duration: 1000 })
      .slide(SlideEffect.Top)
  }

  build() {
    Column() {
      Text(this.message)
    }
    .justifyContent(FlexAlign.Center)
    .height('100%')
    .width('100%')
  }
}
