onBackPress(): boolean | void {  
  return true  
}  
  
secondPage页面完整代码如下：  
import { router } from '@kit.ArkUI';  
  
@Entry  
@Component  
struct secondPage {  
  @State rotateAngle: number = 0;  
  @State speed: number = 0;  
  @State message: string = 'Hello World secondPage';  
  onBackPress(): boolean | void {  
    return true  
  }  
  build() {  
  
    Column(){  
      Button('点击返回上一页')  
        .onClick(()=>{  
          router.back()  
        })  
      RelativeContainer() {  
        Text(this.message)  
          .id('HelloWorld')  
          .fontSize(50)  
          .fontWeight(FontWeight.Bold)  
          .alignRules({  
            center: { anchor: '__container__', align: VerticalAlign.Center },  
            middle: { anchor: '__container__', align: HorizontalAlign.Center }  
          })  
      }  
      .gesture(  
        // 绑定滑动手势且限制仅在水平方向滑动时触发  
        SwipeGesture({ direction: SwipeDirection.Horizontal,fingers:0 })  
          // 当滑动手势触发时，获取滑动的速度和角度，实现对组件的布局参数的修改  
          .onAction((event: GestureEvent|undefined) => {  
            if(event){  
              this.speed = event.speed;  
              this.rotateAngle = event.angle;  
            }  
          })  
      )  
  
  
      .height('100%')  
      .width('100%')  
      .backgroundColor(Color.Green)  
    }  
    //.scrollable(false) // 禁止滑动切换  
  
  }
