Skyline is a skill for developing WeChat mini-program Skyline-engine UI components including scroll lists, swipers, forms, and transition animations.

About

Skyline is a skill for developing WeChat mini-program UI components under the Skyline rendering engine. A developer uses it to build scroll lists and waterfalls, pull-to-refresh, nested scrolling, swiper carousels, form inputs, and shared-element transitions. It enforces Skyline-specific rules such as always setting scroll-view type, using enable-flex for horizontal scroll, and wrapping list-view/grid-view in a custom-mode scroll-view.

  • Guides WeChat Skyline component development for lists, swipers, forms, and animations
  • MUST/NEVER rules for scroll-view type, enable-flex, and nested scroll
  • Covers Skyline-only components like list-view, grid-view, and draggable-sheet

强制规则

MUST(必须遵守)

1. scroll-view 必须指定 type:Skyline 下使用 scroll-view 必须设置 type 属性

   <!-- ✅ 正确 -->
   <scroll-view type="list" scroll-y>...</scroll-view>
   
   <!-- ❌ 错误:缺少 type -->
   <scroll-view scroll-y>...</scroll-view>

2. 横向滚动需 enable-flex:横向滚动需同时开启 enable-flex 以兼容 WebView

   <scroll-view scroll-x enable-flex style="flex-direction: row;">

3. 文本必须用 text 组件:内联文本只能用 <text> 组件

   <!-- ✅ 正确 -->
   <text>Hello <text>World</text></text>
   
   <!-- ❌ 错误:内联文本不能用 view -->
   <view>Hello <view>World</view></view>

4. list-view/grid-view 必须在 custom 模式

   <scroll-view type="custom" scroll-y>
     <list-view>...</list-view>
   </scroll-view>

5. 嵌套滚动必须使用 nested 模式

   <scroll-view type="nested" scroll-y>
     <nested-scroll-header>...</nested-scroll-header>
     <nested-scroll-body>...</nested-scroll-body>
   </scroll-view>

NEVER(禁止行为)

1. NEVER 在 scroll-view 外直接放置 list-view/grid-view 2. NEVER 在 list-view 中使用非直接子节点列表项 3. NEVER 在 Skyline 使用 web-view/editor/movable-view 组件 4. NEVER 依赖 image 的 WebView-only 裁剪模式(top/bottom/center/left/right)

scroll-view 核心用法

type 属性详解

type 值说明使用场景
list列表模式,按需渲染直接子节点普通长列表
custom自定义模式,支持 list-view/grid-view/sticky复杂布局
nested嵌套模式,处理父子 scroll-view 联动Tab + 列表

基础列表模式

<!-- 列表模式:直接子节点按需渲染 -->
<scroll-view 
  type="list" 
  scroll-y
  style="height: 100vh;"
  bindscrolltolower="loadMore"
>
  <view wx:for="{{list}}" wx:key="id">
    {{item.name}}
  </view>
</scroll-view>

下拉刷新

<scroll-view
  type="list"
  scroll-y
  refresher-enabled="{{true}}"
  refresher-triggered="{{refreshing}}"
  bindrefresherrefresh="onRefresh"
>
  <view slot="refresher" class="custom-refresher">
    自定义刷新区域
  </view>
  <!-- 列表内容 -->
</scroll-view>
Page({
  data: { refreshing: false },
  onRefresh() {
    this.setData({ refreshing: true })
    // 加载数据...
    setTimeout(() => {
      this.setData({ refreshing: false })
    }, 1000)
  }
})

嵌套滚动模式

<scroll-view type="nested" scroll-y>
  <nested-scroll-header>
    <view>顶部固定区域</view>
  </nested-scroll-header>
  <nested-scroll-body>
    <swiper>
      <swiper-item wx:for="{{tabs}}" wx:key="id">
        <scroll-view 
          type="list" 
          scroll-y
          associative-container="nested-scroll-view"
        >
          <!-- 列表内容 -->
        </scroll-view>
      </swiper-item>
    </swiper>
  </nested-scroll-body>
</scroll-view>

Worklet 滚动回调

<scroll-view
  type="list"
  scroll-y
  worklet:onscrollupdate="onScrollUpdate"
>
Page({
  onScrollUpdate(e) {
    'worklet'
    // 在 UI 线程执行,无延迟
    console.log(e.detail.scrollTop)
  }
})

swiper 增强特性

布局类型

<!-- 堆叠效果 -->
<swiper layout-type="stackLeft">
  <swiper-item>...</swiper-item>
</swiper>

<!-- 卡片滑动 -->
<swiper layout-type="tinder">
  <swiper-item>...</swiper-item>
</swiper>

<!-- 过渡动画 -->
<swiper layout-type="transformer" transformer-type="threeD">
  <swiper-item>...</swiper-item>
</swiper>

指示器样式

<swiper
  indicator-dots
  indicator-type="worm"
  indicator-color="rgba(0,0,0,0.3)"
  indicator-active-color="#000"
  indicator-margin="10"
  indicator-spacing="4"
>
indicator-type效果
normal默认圆点
worm蠕虫动画
expand展开动画
jump跳跃动画
slide滑动动画
scale缩放动画

text 组件

文本溢出处理

<!-- 单行省略 -->
<text overflow="ellipsis" max-lines="1">
  这是一段很长的文本内容...
</text>

<!-- 多行省略 -->
<text overflow="ellipsis" max-lines="3">
  这是一段很长的文本内容...
</text>

<!-- 渐隐效果 -->
<text overflow="fade" max-lines="1">
  这是一段很长的文本内容...
</text>

内联混排

<!-- 使用 span 实现图文混排 -->
<span>
  <image src="icon.png" style="width:20px;height:20px;" />
  <text>图文混排内容</text>
</span>

input 组件

Skyline 特有事件

<input
  value="{{value}}"
  bindinput="onInput"
  bind:selectionchange="onSelectionChange"
  bind:keyboardcompositionend="onCompositionEnd"
  worklet:onkeyboardheightchange="onKeyboardHeight"
/>
Page({
  onKeyboardHeight(e) {
    'worklet'
    // UI 线程回调,可用于同步调整布局
    const { height, pageBottomPadding } = e.detail
  }
})

draggable-sheet 半屏组件

<draggable-sheet
  class="sheet"
  initial-child-size="0.5"
  min-child-size="0.2"
  max-child-size="0.8"
  snap="{{true}}"
  snap-sizes="{{[0.4, 0.6]}}"
  worklet:onsizeupdate="onSizeUpdate"
>
  <scroll-view
    scroll-y
    type="list"
    associative-container="draggable-sheet"
  >
    <!-- 内容 -->
  </scroll-view>
</draggable-sheet>
Page({
  onReady() {
    this.createSelectorQuery()
      .select('.sheet')
      .node()
      .exec(res => {
        const sheetContext = res[0].node
        sheetContext.scrollTo({
          size: 0.7,
          animated: true,
          duration: 300
        })
      })
  }
})

share-element 共享元素

页面间共享元素动画

源页面:

<share-element key="hero-image" transform>
  <image src="{{item.cover}}" />
</share-element>

目标页面:

<share-element key="hero-image" transform transition-on-gesture>
  <image src="{{detail.cover}}" />
</share-element>

属性说明

属性说明
key页面内唯一标识,源和目标必须匹配
transform是否启用动画
transition-on-gesture手势返回时是否动画
rect-tween-type动画轨迹(materialRectArc/linear)

性能优化

列表性能

1. 使用 list 模式:确保只渲染可见区域

   <scroll-view type="list" scroll-y cache-extent="500">

2. 指定 cache-extent:预渲染视口外区域,优化滚动体验

3. 使用 list-item 属性:启用样式共享

   <view wx:for="{{list}}" wx:key="id" list-item>

swiper 性能

<!-- 使用 cache-extent 预渲染相邻页 -->
<swiper cache-extent="1">
