React Native Head Tab View

:tada::tada::tada: v4.0.0-rc.12 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

``tsx


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.

Features

Example

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

`js
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 {
render() {
return (
}>







)
}
}
`

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

`js
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 = () => (



);

const SecondRoute = () => (



);

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 (
renderScrollHeader={() => }
navigationState={{ index, routes }}
renderScene={renderScene}
onIndexChange={setIndex}
initialLayout={initialLayout}
/>
);
}

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

More examples：Example

Run the example

`sh
cd Example
yarn or npm install

//run Android
react-native run-android

//run iOS
cd ios
pod install
cd ../
react-native run-ios
`

Installation

- The first step is to add the base library and its dependencies

`sh
yarn add react-native-head-tab-view react-native-gesture-handler react-native-reanimated
or
npm install react-native-head-tab-view react-native-gesture-handler react-native-reanimated --save
`

- The second step is to select the extension library based on the tabs component you are using

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

`
yarn add react-native-scrollable-tab-view-collapsible-header
`

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

`
yarn add react-native-tab-view-collapsible-header
`

>`

`
- If your tabs component is react-native-tab-view
>You need to add this dependency library

​`js
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

`js
renderScrollHeader={()=>}
`


##### 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.

`js
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.
