Usage

Create your custom scrollable

 // @flow
 import React from 'react';
 import { ScrollView,Animated } from 'react-native';
 import { defaultProps } from 'recompose';
 import { ListItem, List } from 'react-native-elements';
 import { Scrollable } from 'react-native-collapsible-tab-header';
 import createData from '../data';
 import type { dataType } from '../types';
 
 const AnimatedScrollable = Animated.createAnimatedComponent(ScrollView);
 
 const MyCustomScrollView = Scrollable(AnimatedScrollable);
 
 const Component = ({ data }: {data: Array<dataType>}) => (
   <List>
     <MyCustomScrollView>
       {data.map(item => (
         <ListItem
           key={item.id}
           subtitle={item.subtitle}
           title={item.title}
         />
       ))}
     </MyCustomScrollView>
   </List>
 );
 
 Component.propTypes = {};
 Component.defaultProps = {};
 
 export default defaultProps({
   data: createData(25),
 })(Component);

or use one of in built scrollables like the flatlist or scrollview

// @flow
import React from 'react';
import { defaultProps } from 'recompose';
import { ListItem, List } from 'react-native-elements';
import { FlatList } from 'react-native-collapsible-tab-header';
import createData from '../data';
import type { dataType } from '../types';

const Component = ({ data }: {data: Array<dataType>}) => (
 <List>
   <FlatList
     data={data}
     keyExtractor={(item: dataType) => item.id}
     renderItem={({ item }: {item: dataType}) => (
       <ListItem
         subtitle={item.subtitle}
         title={item.title}
       />
     )}
   />
 </List>
);

Component.propTypes = {};
Component.defaultProps = {};

export default defaultProps({
 data: createData(25),
})(Component);

create your collapsible tab component

// @flow
import React from 'react';
import { View, Text } from 'react-native';
import { compose, defaultProps } from 'recompose';
import { ItemsScrollView, ItemsFlatList, ItemsCustomList } from '../components/index';
import { Collapsible, Tabs, TabHeader, Tab } from 'react-native-collapsible-tab-header';
import styles from '../style';


const ICON_TYPE = 'simple-line-icon';
const USERS_ICON = 'people';
const ROUTE_ICON = 'location-pin';
const PRODUCT_ICON = 'grid';
const REPORT_ICON = 'chart';

const Component = ({ style }: {style: Object}) => (
  <Collapsible hasNavBar={false} style={{ backgroundColor: 'snow' }} height={'35%'}>
    <View style={style.container} >
      <Tabs
        style={style.tabs}
        tabStyle={style.tab}
        labelStyle={style.label}
        routes={[
          { key: 'flat-list', title: 'FlatList', icon: { type: ICON_TYPE, name: USERS_ICON } },
          { key: 'scroll-view', title: 'ScrollView', icon: { type: ICON_TYPE, name: PRODUCT_ICON } },
          { key: 'custom', title: 'Custom', icon: { type: ICON_TYPE, name: ROUTE_ICON } },
          { key: 'content', title: 'Content', icon: { type: ICON_TYPE, name: REPORT_ICON } },
        ]}
      >
        <TabHeader>
          <View>
            <Text>This is a header content</Text>
          </View>
        </TabHeader>
        <Tab key={'flat-List'}>
          <ItemsFlatList />
        </Tab>
        <Tab key={'scroll-view'}>
          <ItemsScrollView />
        </Tab>
        <Tab key={'custom'}>
          <ItemsCustomList />
        </Tab>
        <Tab hasScrollable={false} key={'content'}>
          <Text> this is just a content </Text>
        </Tab>
      </Tabs>
    </View>
  </Collapsible>
);

export default compose(
  defaultProps({ style: styles }),
)(Component);

or without tabs

    // @flow
    import React from 'react';
    import { View, Text } from 'react-native';
    import { compose, defaultProps } from 'recompose';
    import { ItemsCustomList } from '../components/index';
    import { Collapsible, Header } from 'react-native-collapsible-tab-header';
    import styles from '../style';
    
    
    const Component = ({ style }: {style: Object}) => (
      <Collapsible hasNavBar={false} style={{ backgroundColor: 'snow' }} height={'35%'}>
        <View style={style.container} >
    
          <Header>
            <View>
              <Text>This is a header content</Text>
            </View>
          </Header>
          <ItemsCustomList />
        </View>
      </Collapsible>
    );
    
    export default compose(
      defaultProps({ style: styles }),
    )(Component);

API

Collapsible:

React native parent component to create collapsible component Props 1. height(number | string)-default('30%'): height of collapsible header in either percentage or fixed length. 2. collapseHeight(string)-default('50%): height in header to respond with closing or opening header during a scroll. 3. offsetFromTop(number)-default(20 for android 24 for ios,0 when hasNavBar is false): offset to from top when collapsed to manage situations such as when there is no navbar,or you wish to keep a part of the header showing when collapsed. 4. hasNavBar(bool)-default(true) helps with offsetFromTop for determining offset for status bar of device.

Tabs:

Parent Component to manage tabs for collapsible Props 1. routes(Array of Routes ({icon:{name:string,type:string, ...propsFrom react-native-elements icon}))-default([]):

iconStyle (object)-default({ fontSize: 18, color:#FFFFFF }) :style for icons
activeIconStyle (object)-default({ fontSize: 18, color:#FFFFFF }) :style for active icons
inactiveIconStyle (object)-default({ fontSize: 18, color:#FFFFFF }) :style for in-active icons
labelStyle (object)-default({ fontSize: 12, color:#FFFFFF }) :style for in-active icons
indicatorStyle (object)-default({backgroundColor: #FFFFFF }) :style for in-active icons
swipeEnabled (bool)-default(true) : enable/disable tab swipe navigation
tabsProps (object)-default(undefined) : props for tabs, same as props for tabViewAnimated
All props from the excellent react-native-tab-view tabBar

TabHeader:

Header component for tabs children: react component for header Props: 1. styles(Object)-default({ backgroundColor: #FFFFFF, flex: 1 }): style for header component; 2. onHeaderContentLayout(func)):function to return layout props for header content without tab dimensions 3.onLayout(func)):function to return layout props for tabheader

Tab:

Tab component to display tab content note this is a pure component and will update contents when hasScrollable changes to improve performance: it should generally work well Props 1. key(string): key same as key in routes 2. hasScrollable(boolean)-default(true): set this to fault when the tab content is not a scrollable to properly align items.

Scrollable(ScrollableComponent:React Native Componet):

Method to create a scrollable component to control collapsible header

FlatList:

Scrollable flatlist component from Scrollable() method, same as RN FlatList

ScrollView:

Scrollable Scrollview component from Scrollable() method, same as RN ScrollView

Motivation:

Needed an easy way to implement collapsible tab headers and headers for a project and could not find one .. so I created this to ease the burden for myself and perhaps others.

Acknowledgments:

Indeed I could not have achieved this without the excellent contributions from others such as 1. @janicduplessis for his excellent medium post 2. brilliant tab view from react-native-community 3. awesome icon implementation and components from react-native-elements 4. recompose - so cool! 5. React and ReactNative - just makes a lot of sense :)
