@Entry
@Component
struct Index {
  build() {
    Column() {
      Swiper() {
        Text('公告')
          .width('80%')
          .fontSize(20)
          .textAlign(TextAlign.Center)
          .gesture(TapGesture({ distanceThreshold: 50 }).onAction((event: GestureEvent) => {
            if (event) {
              this.getUIContext().getPromptAction().showToast({ message: '通知详情', alignment: Alignment.Top })
            }
          }))
      }
      .height('20%')
      .vertical(true)
    }
    .width('100%')
    .height('100%')
