Well, I've solved that scenario using react-native-swiper
Basically you have to wrap all views you want to have inside a Swiper, render and style the header as you want.
Here there is a working example I've made:
render() {
return (
<View style={styles.body}>
<Swiper
height={500}
showsPagination={true}
loop={false}
renderPagination={this._renderPagination}
ref={component => this._swiper = component}>
<View style={styles.page}>
<FlatList data={..} renderItem={item => ...} keyExtractor={(item, index) => index} />
</View>
<View style={styles.page}>
<FlatList data={...} renderItem={item => ...} keyExtractor={(item, index) => index} />
</View>
<View style={styles.page}>
<FlatList data={...} renderItem={item => ...} keyExtractor={(item, index) => index} />
</View>
<View style={styles.page}>
<FlatList data={...} renderItem={item => ...} keyExtractor={(item, index) => index} />
</View>
</Swiper>
</View>
);
}
_renderPagination(index, total, context) {
return (
<View style={styles.pagination}>
{this._renderPaginationHeaders(index, total, context)}
</View>
)
}
_renderPaginationHeaders(index, total, context) {
let ret = [];
for (let i = 0; i < total; i++) {
ret.push(
<TouchableOpacity key={i} style={{ flex: 1, flexDirection: 'column' }} onPress={() => this._onPageChange(i)}>
<Text style={[styles.title, { flex: 1, textAlign: 'center', textAlignVertical: 'center' }]}>
{this._getSectionText(i)}
</Text>
<View style={{ height: 5, backgroundColor: index === i ? 'magenta' : 'transparent' }}></View>
</TouchableOpacity>
);
}
return ret;
}
_onPageChange(targetIndex) {
const currentIndex = this._swiper.state.index;
const offset = targetIndex - currentIndex;
this._swiper.scrollBy(offset);
}
const styles = StyleSheet.create({
body: {
flex: 1,
alignItems: 'center',
alignSelf: 'center',
backgroundColor: '#f1f1f1',
},
pagination: {
flexDirection: 'row',
width: Dimensions.get('window').width,
height: Header.currentHeight * 0.7,
backgroundColor: '#2E2E2E',
paddingLeft: 2,
paddingRight: 2,
alignItems: 'center',
position: 'absolute',
top: 0,
},
page: {
flex: 1,
marginTop: (Header.currentHeight * 0.7) + 3
},
title: {
color: 'white'
},
});
