React Native Head Tab View

🎉🎉🎉 v4.0.0-rc.13 has been released, I hope you can help me test and collect questions. In this version, there is a big change. All animations will run on the UI thread, which will make the components much smoother. Unfortunately, the version requiring React Native is greater than 0.62.0. Because we rely on react-native-reanimated2.0, that's what it requires.

Here are some changes and optimizations. Disruptive Changes:

• Remove makeHeaderHeight and change it to headerHeight

It's not mandatory, but it would be nice if you did

• Removed SlideAnimated mode

this mode was used for ScrollView/FlatList scrolling stalling when dragging headers, no longer needed.

• Remove the scene's refreshHeight property
  Both the TabView and Scene used to have the refreshHeight property. Now I think they are duplicate, just set refreshHeight on the TabView, its default value is 80

• The usage of HPageViewHoc has changed

# Past usage:
import { HPageViewHoc } from 'react-native-head-tab-view'
const HScrollView = HPageViewHoc(ScrollView)
const HFlatList = HPageViewHoc(FlatList)
const HSectionList = HPageViewHoc(SectionList)
# Current usage
import { HScrollView,HFlatList,HSectionList } from 'react-native-head-tab-view'

The following components are currently supported:
react-native-scrollable-tab-view
react-native-tab-view

For detailed usage, please refer to Example and Installation.

Demo

Example

If your tabs component is react-native-scrollable-tab-view

import * as React from 'react';
import { View } from 'react-native';
import { HScrollView } from 'react-native-head-tab-view'
import { CollapsibleHeaderTabView } from 'react-native-scrollable-tab-view-collapsible-header'
export default class ExampleBasic extends React.PureComponent<any> {
    render() {
        return (
            <CollapsibleHeaderTabView renderScrollHeader={() => <View style={{ height: 200, backgroundColor: 'red' }} />}>
                <HScrollView index={0}>
                    <View style={{ height: 1000, backgroundColor: '#ff4081' }} />
                </HScrollView>
                <HScrollView index={1}>
                    <View style={{ height: 1000, backgroundColor: '#673ab7' }} />
                </HScrollView>
            </CollapsibleHeaderTabView>
        )
    }
}

If your tabs component is react-native-tab-view

import * as React from 'react';
import { View, StyleSheet, Dimensions } from 'react-native';
import { SceneMap } from 'react-native-tab-view';
import { HScrollView } from 'react-native-head-tab-view'
import { CollapsibleHeaderTabView } from 'react-native-tab-view-collapsible-header'

const FirstRoute = () => (
    <HScrollView index={0}>
        <View style={[styles.scene, { backgroundColor: '#ff4081' }]} />
    </HScrollView>
);

const SecondRoute = () => (
    <HScrollView index={1}>
        <View style={[styles.scene, { backgroundColor: '#673ab7' }]} />
    </HScrollView>
);

const initialLayout = { width: Dimensions.get('window').width };

export default function TabViewExample() {
    const [index, setIndex] = React.useState(0);
    const [routes] = React.useState([
        { key: 'first', title: 'First' },
        { key: 'second', title: 'Second' },
    ]);

    const renderScene = SceneMap({
        first: FirstRoute,
        second: SecondRoute,
    });

    return (
        <CollapsibleHeaderTabView
            renderScrollHeader={() => <View style={{ height: 200, backgroundColor: 'red' }} />}
            navigationState={{ index, routes }}
            renderScene={renderScene}
            onIndexChange={setIndex}
            initialLayout={initialLayout}
        />
    );
}

const styles = StyleSheet.create({
    scene: {
        flex: 1,
    },
});

CollapsibleHeaderTabView

• If your tabs component is react-native-scrollable-tab-view

You need to add this dependency library

import { CollapsibleHeaderTabView } from 'react-native-scrollable-tab-view-collapsible-header' 

• If your tabs component is react-native-tab-view

You need to add this dependency library

import { CollapsibleHeaderTabView } from 'react-native-tab-view-collapsible-header' 

CollapsibleHeaderTabView extends the props for the tabs component by adding the CollapsibleHeaderProps

CollapsibleHeaderProps

renderScrollHeader (React.ComponentType | React.ReactElement | null) (require)

render the collapsible header

renderScrollHeader={()=><View style={{height:180,backgroundColor:'red'}}/>}

headerHeight (optional)

The height of collapsible header.

tabbarHeight (optional)

The height of collapsible tabbar

frozeTop

The height at which the top area of the Tabview is frozen

overflowHeight

Sets the upward offset distance of the TabView and TabBar

makeScrollTrans (scrollValue: Animated.ShareValue) => void

Gets the animation value of the shared collapsible header.

<CollapsibleHeaderTabView
    makeScrollTrans={(scrollValue) => {
        this.setState({ scrollValue })
    }}
/>

onStartRefresh (() => void)

If provided, a standard RefreshControl will be added for "Pull to Refresh" functionality.
Make sure to also set the isRefreshing prop correctly.

isRefreshing (boolean)

Whether the TabView is refreshing

renderRefreshControl (() => React.ReactElement)

A custom RefreshControl

scrollEnabled (boolean)

Whether to allow the scene to slide vertically

refreshHeight (number)

If this height is reached, a refresh event will be triggered （onStartRefresh）
it defaults to 80

overflowPull (number)

It's the distance beyond the refreshHeight, the distance to continue the displacement, when the pull is long enough,
it defaults to 50.

pullExtendedCoefficient (number)

When the maximum drop-down distance is reached(refreshHeight+overflowPull), the refreshControl moves the distance for each pixel the finger moves The recommended number is between 0 and 1.

---

HScrollView \ HFlatList \ HSectionList

index (number) (require)

The number of the screen.
If you use react-native-scrollable-tab-view, it should correspond to the number of the children element in the TabView.

If you use react-native-tab-view, it should correspond to the index of the navigationState of the TabView
Please check the Example .

onStartRefresh (() => void)

If provided, a standard RefreshControl will be added for "Pull to Refresh" functionality.
Make sure to also set the isRefreshing prop correctly.

isRefreshing (boolean)

Whether the scene is refreshing

renderRefreshControl (() => React.ComponentType | React.ReactElement | null)

A custom RefreshControl for scene

renderLoadingView ((headerHeight: number) => React.ReactElement)

You can provide a LoadingView when the scene is transparent until the height of the onContentSizeRange callback is less than minHeight.

enableSnap (boolean)

When it stops sliding, it automatically switches to the folded and expanded states.

Tips.

1. If you are not planning to upgrade to RN0.62 in the near future, you can use the v3 version.
2. You may encounter problems with React-Native-Reanimated2.0 when you first start using V4.

Refer to the official documentation. I'm sure it won't be difficult for you

Thank you for your effort.
