Basic usage

import RnScrolltabView from 'ray-rn-scrolltab';

<RnScrolltabView>
  <Page01 tabLabel="page1" />
  <Page02 tabLabel="page2" />
  <Page03 tabLabel="page3" />
</RnScrolltabView>

// not render tab bar
<RnScrolltabView renderTabBar={false}>
  <Page01 tabLabel="page1" />
  <Page02 tabLabel="page2" />
  <Page03 tabLabel="page3" />
</RnScrolltabView>

Custom Tab Bar

Suppose we had a custom tab bar called CustomTabBar or use DefaultTabBar, we would inject it into our RnScrolltabView like this:

import RnScrolltabView, { DefaultTabBar, ScrollTabBar } from 'ray-rn-scrolltab';

<RnScrolltabView renderTabBar={() => <DefaultTabBar />}>
  <Page01 tabLabel="page1" />
  <Page02 tabLabel="page2" />
  <Page03 tabLabel="page3" />
</RnScrolltabView>

// or
// import CustomTabBar from './CustomTabBar';
<RnScrolltabView renderTabBar={() => <CustomTabBar {...yourProp} />}>
  <Page01 tabLabel="page1" />
  <Page02 tabLabel="page2" />
  <Page03 tabLabel="page3" />
</RnScrolltabView>

more example

import RnScrolltabView, { ScrollTabBar } from 'ray-rn-scrolltab';

export default () => {
  return <RnScrolltabView
    style={{marginTop: 20, }}
    initialPage={0}
    renderTabBar={() => <ScrollTabBar />}
  >
    <Text tabLabel='Tab#1'>My</Text>
    <Text tabLabel='Tab#2 word word'>favorite</Text>
    <Text tabLabel='Tab#3 word word word'>project</Text>
    <Text tabLabel='Tab#4 word word word word'>favorite</Text>
    <Text tabLabel='Tab#5'>project</Text>
  </RnScrolltabView>;
}

// Overlay
import { ScrollView } from 'react-native';
export default () => {
  return <RnScrolltabView
    style={styles.container}
    renderTabBar={()=><DefaultTabBar backgroundColor='rgba(255, 255, 255, 0.7)' />}
    tabBarPosition='overlayTop'
  >
    <ScrollView tabLabel='iOS'>
      <Image source={require('./1.png')}/>
      <Image source={require('./2.png')}/>
      <Image source={require('./3.png')}/>
      <Image source={require('./4.png')}/>
    </ScrollView>
    <ScrollView tabLabel='Android'>
      <Image source={require('./1.png')}/>
      <Image source={require('./2.png')}/>
      <Image source={require('./3.png')}/>
      <Image source={require('./4.png')}/>
    </ScrollView>
  </ScrollableTabView>;
}
