前言

页面转场动画是指在应用程序中，当用户导航到另一个页面时，使用动画效果来过渡页面之间的切换。这样做的目的是为了提升用户体验，使页面之间的切换更加平滑和有趣。

常见的页面转场动画包括淡入淡出、滑动、翻转、缩放等效果。通过使用这些动画效果，可以给用户一种流畅的感觉，让页面之间的切换更加自然。

在实现页面转场动画时，可以根据具体的需求和设计来选择合适的转场效果，并结合页面的布局和内容来调整动画效果的细节。

页面转场动画是一种通过使用动画效果来过渡页面切换的方式，旨在提升用户体验，使页面之间的切换更加平滑和有趣。

一、页面转场动画

1.type配置

PageTransitionEnter和PageTransitionExit的接口为：

  1.  class="hljs-ln-numbers"> class="hljs-ln-line hljs-ln-n" data-line-number="1">
class="hljs-ln-code"> class="hljs-ln-line">PageTransitionEnter({type?: RouteType,duration?: number,curve?: Curve | string,delay?: number})
  • class="hljs-ln-numbers"> class="hljs-ln-line hljs-ln-n" data-line-number="2">
    • class="hljs-ln-code"> class="hljs-ln-line">
  • class="hljs-ln-numbers"> class="hljs-ln-line hljs-ln-n" data-line-number="3"> class="hljs-ln-code"> class="hljs-ln-line">PageTransitionExit({type?: RouteType,duration?: number,curve?: Curve | string,delay?: number})
    •  class="hljs-button signin active" data-title="登录复制" data-report-click="{"spm":"1001.2101.3001.4334"}" onclick="hljs.signin(event)">

    在HarmonyOS中，PageTransitionEnter和PageTransitionExit是用于控制页面切换动画的参数。它们分别表示页面进入和退出时的动画。

    1. type（动画类型）：表示动画的类型，可以取以下几种值：

    2. duration（动画时长）：表示动画的时长，单位为毫秒。

    3. curve（动画曲线）：表示动画的变化曲线。

    4. delay（动画延迟）：表示动画的延迟时间，单位为毫秒。

    通过设置页面转场的时长为0，可使该页面无页面转场动画。
