1e41f4b71Sopenharmony_ci# Swiper
2e41f4b71Sopenharmony_ci
3e41f4b71Sopenharmony_ci 滑块视图容器,提供子组件滑动轮播显示的能力。 
4e41f4b71Sopenharmony_ci
5e41f4b71Sopenharmony_ci> **说明:**
6e41f4b71Sopenharmony_ci>
7e41f4b71Sopenharmony_ci> - 该组件从API Version 7开始支持。后续版本如有新增内容,则采用上角标单独标记该内容的起始版本。
8e41f4b71Sopenharmony_ci>
9e41f4b71Sopenharmony_ci> - Swiper组件[通用属性clip](ts-universal-attributes-sharp-clipping.md)的默认值为true。
10e41f4b71Sopenharmony_ci>
11e41f4b71Sopenharmony_ci> - Swiper组件内包含了[PanGesture](ts-basic-gestures-pangesture.md)拖动手势事件,用于滑动轮播子组件。[disableSwipe](#disableswipe8)属性设为true会取消内部的PanGesture事件监听。

13e41f4b71Sopenharmony_ci## 子组件
14e41f4b71Sopenharmony_ci
15e41f4b71Sopenharmony_ci可以包含子组件。
16e41f4b71Sopenharmony_ci
17e41f4b71Sopenharmony_ci>  **说明:** 
18e41f4b71Sopenharmony_ci>
19e41f4b71Sopenharmony_ci>  - 子组件类型:系统组件和自定义组件,支持渲染控制类型([if/else](../../../quick-start/arkts-rendering-control-ifelse.md)、[ForEach](../../../quick-start/arkts-rendering-control-foreach.md)、[LazyForEach](../../../quick-start/arkts-rendering-control-lazyforeach.md)和[Repeat](../../../quick-start/arkts-new-rendering-control-repeat.md))。不建议子组件中混用懒加载组件(包括LazyForEach、Repeat)和非懒加载组件,或者子组件中使用多个懒加载组件,否则可能导致懒加载组件预加载能力失效等问题。
20e41f4b71Sopenharmony_ci>
21e41f4b71Sopenharmony_ci>  - Swiper子组件的visibility属性设置为None,Swiper的displayCount属性设置为'auto'时,对应子组件在视窗内不占位,但不影响导航点个数。
22e41f4b71Sopenharmony_ci>
23e41f4b71Sopenharmony_ci>  - Swiper子组件的visibility属性设置为None,或者visibility属性设置为Hidden时,对应子组件不显示,但依然会在视窗内占位。
24e41f4b71Sopenharmony_ci>
25e41f4b71Sopenharmony_ci>  - 当Swiper子组件个数小于等于Swiper组件内容区内显示的节点总个数(totalDisplayCount = DisplayCount + prevMargin? (1 : 0) + nextMargin? (1 : 0))时,一般按照非循环模式布局处理,此时,前后边距对应子组件不显示,但依然会在视窗内占位。Swiper组件按照totalDisplayCount个数判断测算规格。例外情况如下:
26e41f4b71Sopenharmony_ci>    
27e41f4b71Sopenharmony_ci>    - 当Swiper子组件个数等于Swiper组件内容区内显示的节点总个数且prevMargin和nextMargin都生效时,设置loop为true支持循环。
28e41f4b71Sopenharmony_ci>
29e41f4b71Sopenharmony_ci>    - 当Swiper子组件个数等于Swiper组件DisplayCount数 + 1,且prevMargin和nextMargin至少一个生效时,设置loop为true会生成截图占位组件(如果使用图片异步加载等显示耗时较长的组件可能不能正确生成截图,不建议在该场景开启循环),支持循环。
30e41f4b71Sopenharmony_ci>
31e41f4b71Sopenharmony_ci>  - 当Swiper子组件设置了offset属性时,会按照子组件的层级进行绘制,层级高的子组件会覆盖层级低的子组件。例如,Swiper包含3个子组件,其中第3个子组件设置了offset({ x : 100 }),那么在横向循环滑动中,第3个子组件会覆盖第1个子组件,此时可设置第1个子组件的zIndex属性值大于第3个子组件,使第1个子组件层级高于第3个子组件。
32e41f4b71Sopenharmony_ci>
33e41f4b71Sopenharmony_ci>  - 不建议在执行翻页动画过程中增加或减少子组件,会导致未进行动画的子组件提前进入视窗,引起显示异常。
