Predefined headers can be accessed through headerType="HeaderName" property, each header can be configured according to your demands using the wide amount of properties. You can change all of them, or use it right out of the box with as little changes as possible to use it for you needs:)

This is how you can add them in your app:

import React from 'react'

const TestScreen = () => (
  <React.Fragment>

    {/* <StickyParalaxHeader headerType="AvatarHeader" /> */}
    {/* <StickyParalaxHeader headerType="DetailsHeader" /> */}

Getting Started

Prerequisites

Installation

$ yarn add react-native-sticky-parallax-header
Enter fullscreen mode Exit fullscreen mode

In order to make tab bar work, we have to link react-native-nested-scroll-view package.

$ react-native link react-native-nested-scroll-view
Enter fullscreen mode Exit fullscreen mode

Depending on the version of React Native you use, the package can be still making issues for you, you have to install patch-package

$ yarn add patch-package postinstall-postinstall
Enter fullscreen mode Exit fullscreen mode

Then you add this script to your scripts:

 "scripts": {
+  "postinstall": "patch-package"
 }
Enter fullscreen mode Exit fullscreen mode

After all those steps, just copy a 'patches' folder from this repository and run yarn again to apply the patched package.
You're ready to use the package now.

Running/Development

  1. iOS:
$ react-native run-ios
Enter fullscreen mode Exit fullscreen mode
  1. Android:
$ react-native run-android
Enter fullscreen mode Exit fullscreen mode

Running Tests

$ yarn test
Enter fullscreen mode Exit fullscreen mode

Creating new Pull Request

  • remember to add appropriate title, ticket, description
  • adding video or screenshot is very beneficial but it's not mandatory
  • additionally please remember to add appropriate Pull Request title from following:
    • [RNS-XX] short description - for normal feature branches

Code structure

src/
├──assets
├──components
├──constants
├──predefinedComponents
Enter fullscreen mode Exit fullscreen mode

Code Style

  • Make sure you are using linter with linting rules defined in ESLint config (.eslinrc)
  • Name branch according to your ticket following this pattern: RNS-XX-short_description
  • Imports and exports inside index.js files eg. screens/index.js, components/index.js should be alfabetically
  • Style names in ComponentName.styles.js should be ordered alfabetically

Usage

Here is a basic example of how to create a custom header

import React from 'react'
import { Text, View, Animated, StyleSheet } from 'react-native'
import StickyParallaxHeader from 'react-native-sticky-parallax-header'

const styles = StyleSheet.create({
  content: {
    height: 1000,
    marginTop: 50
  },
  foreground: {
    flex: 1,
    justifyContent: 'flex-end'
  },
  message: {
    color: 'white',
    fontSize: 40,
    paddingTop: 24,
    paddingBottom: 7
  },
  headerWrapper: {
    backgroundColor: 'green',
    width: '100%',
    paddingHorizontal: 24,
    paddingBottom: 25,
    flexDirection: 'row',
    alignItems: 'center'
  },
  headerTitle: {
    fontSize: 16,
    color: 'white',
    margin: 12
  },
  tabsWrapper: {
    paddingVertical: 12
  },
  tabTextContainerStyle: {
    backgroundColor: 'transparent',
    borderRadius: 18
  },
  tabTextContainerActiveStyle: {
    backgroundColor: 'lightgreen'
  },
  tabText: {
    fontSize: 16,
    lineHeight: 20,
    paddingHorizontal: 12,
    paddingVertical: 8,
    color: 'white'
  }
})

class TabScreen extends React.Component {
  state = {
    scroll: new Animated.Value(0)
  }

  componentDidMount() {
    const { scroll } = this.state
    scroll.addListener(({ value }) => (this._value = value))
  }

  renderContent = (label) => (
    <View style={styles.content}>
      <Text>{label}</Text>
    </View>
  )

  renderForeground = () => {
    const { scroll } = this.state
    const titleOpacity = scroll.interpolate({
      inputRange: [0, 106, 154],
      outputRange: [1, 1, 0],
      extrapolate: 'clamp'
    })

    return (
      <View style={styles.foreground}>
        <Animated.View style={{ opacity: titleOpacity }}>
          <Text style={styles.message}>STICKY HEADER</Text>
        </Animated.View>
      </View>
    )
  }

  renderHeader = () => {
    const { scroll } = this.state
    const opacity = scroll.interpolate({
      inputRange: [0, 160, 210],
      outputRange: [0, 0, 1],
      extrapolate: 'clamp'
    })

    return (
      <View style={styles.headerWrapper}>
        <Animated.View style={{ opacity }}>
          <Text style={styles.headerTitle}>STICKY HEADER</Text>
        </Animated.View>
      </View>
    )
  }

  render() {
    const { scroll } = this.state

    return (
      <StickyParallaxHeader
        foreground={this.renderForeground()}
        header={this.renderHeader()}
        parallaxHeight={200}
        headerHeight={90}
        headerSize={() => {}}
        onEndReached={() => {}}
        scrollEvent={Animated.event([{ nativeEvent: { contentOffset: { y: scroll } } }])}
        tabs={[
          {
            title: 'First Tab',
            content: this.renderContent('FIRST TAB')
          },
          {
            title: 'Second Tab',
            content: this.renderContent('SECOND TAB')
          },
          {
            title: 'Third Tab',
            content: this.renderContent('THIRD TAB')
          },
          {
            title: 'Fourth Tab',
            content: this.renderContent('FOURTH TAB')
          },
          {
            title: 'Fifth Tab',
            content: this.renderContent('FIFTH TAB')
          }
        ]}
        tabTextStyle={styles.tabText}
        tabTextContainerStyle={styles.tabTextContainerStyle}
        tabTextContainerActiveStyle={styles.tabTextContainerActiveStyle}
        tabsContainerBackgroundColor={'green'}
        tabsWrapperStyle={styles.tabsWrapper}
      >
      </StickyParallaxHeader>
    )
  }
}
Enter fullscreen mode Exit fullscreen mode

Tips

In order to nest scrollable component use scrollEnabled={false} on it and move all the logic to the header eg. by using onEndReached prop.
