NestedScrollView
是一个 React Native 原生 UI 组件。
主要用来实现如下结构的视图:
最外层是一个可纵向滚动的视图, 也就是我们的 NestedScrollView
, 它的子组件往往由一个头部和一个可横向滚动的视图组成。
这个可横向滚动的视图在 React Native 中通常是设置了 horizontal
属性的 ScrollView
,也可以是 PagerView
。
最里层是若干也可以纵向滚动的视图,譬如 ScrollView
、FlashList
、WebView
等等。
NestedScrollView
的作用是协调最里层和最外层可滚动视图之间的(纵向)滚动,使得滚动体验更加流畅。

NestedScrollView
在使用上比较简单
import { NestedScrollView, NestedScrollViewHeader } from '@sdcx/nested-scroll'
const App = () => {
return (
<NestedScrollView>
<NestedScrollViewHeader stickyHeaderBeginIndex={1}>
<Image />
<TabBar />
</NestedScrollViewHeader>
<PagerView>
<FlatList nestedScrollEnabled />
<ScrollView nestedScrollEnabled />
<WebView />
</PagerView>
</NestedScrollView>
)
}
:exclamation: :exclamation: :exclamation: Android 是基于 NestedScrolling API 实现的。
请记得为你的列表开启 `nestedScrollEnabled` 属性。

NestedScrollView
只有两个属于自己的属性
bounces
:仅限于 iOS 平台,用于设置 NestedScrollView
是否有弹性,默认为 false
。一旦设置为 true
,最内层可滚动视图将失去弹性。
contentContainerStyle
:仅限于 Android 平台,用于设置 NestedScrollView
的 contentView 的样式。
stickyHeaderBeginIndex
,它表示从第几个子组件开始,子组件将会被固定在顶部。
stickyHeight
,它表示 header 多高的区域将会被固定在顶部,优先级高于 stickyHeaderBeginIndex
。
onScroll
, 是一个回调函数,可用于实现头部视图的视差效果。
type OnScroll = (event: {
nativeEvent: {
contentOffset: {
x: number
y: number
}
}
}) => void
