Open a Terminal in the project root and run:
yarn add react-native-collapsible-segmented-view
expo install @react-native-community/segmented-controlimport React from 'react'
import { View, StyleSheet, ListRenderItem, Text } from 'react-native'
import { Segmented } from 'react-native-collapsible-segmented-view'
const Header = () => {
return (
<View style={styles.box} pointerEvents="box-none">
<Text style={styles.text}>Collapsible Header</Text>
</View>
)
}
const Example: React.FC = () => {
return (
<Segmented.View header={Header}>
<Segmented.Segment label="A" component={SegmentA} />
<Segmented.Segment label="B" component={SegmentB} />
<Segmented.Segment label="C" component={SegmentC} />
</Segmented.View>
)
}
const buildRenderItem = (color0: string, color1: string) => {
const renderItem: ListRenderItem<number> = (data) => {
const backgroundColor = data.index % 2 === 0 ? color0 : color1
const color = data.index % 2 === 0 ? color1 : color0
return (
<View style={[styles.box, { backgroundColor }]}>
<Text style={[{ color }, styles.text]}>{data.index}</Text>
</View>
)
}
return renderItem
}
const buildSegment = (data: number[], color0: string, color1: string) => {
const Segment = () => {
return (
<Segmented.FlatList
data={data}
renderItem={buildRenderItem(color0, color1)}
keyExtractor={(v) => v ''}
/>
)
}
return Segment
}
const data0 = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
const data1 = [0, 1]
const SegmentA = buildSegment(data0, '#FBC02D', '#FFF9C4')
const SegmentB = buildSegment(data0, '#0097A7', '#B2EBF2')
const SegmentC = buildSegment(data1, '#D32F2F', '#FFCDD2')
const styles = StyleSheet.create({
box: {
justifyContent: 'center',
alignItems: 'center',
height: 250,
width: '100%',
},
text: {
fontSize: 32,
},
})
export default ExampleBasic usage looks like this:
import { Segmented } from 'react-native-collapsible-segmented-view'
const Example = () => {
return (
<Segmented.View hader={MyHeader}>
<Segmented.Segment label="A" component={ScreenA} />
<Segmented.Segment label="B" component={ScreenB} />
<Segmented.Segment label="C" component={ScreenC} />
</Tabs.Container>

Wrap your screens with Segmented.Segment. Basic usage looks like this:
<Segmented.View ...>
<Segmented.Segment label="A" component={ScreenA} />
<Segmented.Segment label="B" component={ScreenB} />
<Segmented.Segment label="C" component={ScreenC} />
</Segmented.Container>| name | type |

Use like a regular flatlist.
Use like a regular ScrollView.
Default iOS control. Props are passed down to the original SegmentedControl.

Returns true if the segment is focused, else returns false.
const isFocused = useIsFocused()Returns the current segment selected index.
const selectedIndex = useSelectedIndex()Returns translateY interpolation and the height of the header. See the animated header example.
const { translateY, height } = useHeaderMeasurements()If you are looking for a full-featured tab bar with swiping, scrollable tabs, dynamic rendering, snapping and diffClamp:
