Info

new version of react-native-parallax-scroll-view I published this because the height for the page was much longer than it needed to be.

Animated Driver

This component now uses Native Driver by default. Remember to pass a Animated component to renderScrollComponent, by default it has Animated.ScrollView

Example

1import ParallaxScrollView from 'react-native-parallax-scroll-view-new';
2import CustomScrollView from 'custom-scroll-view'
3
4const AnimatedCustomScrollView = Animated.createAnimatedComponent(CustomScrollView)
5
6render() {
7  return (
8    <ParallaxScrollView
9      backgroundColor="blue"
10      contentBackgroundColor="pink"
11      parallaxHeaderHeight={300}
12      // renderScrollComponent={() => <Animated.View />}
13      renderScrollComponent={() => <AnimatedCustomScrollView />}
14      renderForeground={() => (
15       <View style={{ height: 300, flex: 1, alignItems: 'center', justifyContent: 'center' }}>
16          <Text>Hello World!</Text>
17        </View>
18      )}>
19      <View style={{ height: 500 }}>
20        <Text>Scroll me</Text>
21      </View>
22    </ParallaxScrollView>
23  );
24}

Usage (API)

All of the properties of ScrollView are supported. Please refer to the ScrollView documentation for more detail.

The ParallaxScrollView component adds a few additional properties, as described below.

Property	Type	Required	Description
backgroundColor	string	No	The color of the header background. Defaults to #000)
backgroundSpeed	number	No	The speed factor that the background moves at relative to the foreground. Defaults to 5.
contentBackgroundColor	string	No	This is the background color of the content. (Defaults to '#fff')
fadeOutForeground	bool	No	If true, the foreground will fade out as the user scrolls up. (Defaults to true)
onChangeHeaderVisibility	func	No	A callback function that is invoked when the parallax header is hidden or shown (as the user is scrolling). Function is called with a boolean value to indicate whether header is visible or not.
parallaxHeaderHeight	number	Yes	This is the height of parallax header.
renderBackground	func	No	This renders the background of the parallax header. Can be used to display cover images for example. (Defaults to an opaque background using backgroundColor)
renderFixedHeader	func	No	This renders an optional fixed header that will always be visible and fixed to the top of the view (and sticky header). You should set its height and width appropriately.
renderForeground	func	No	This renders the foreground header that moves at same speed as scroll content.
renderScrollComponent	func	No	A function with input props and outputs an Animated.ScrollView-like component in which the content is rendered. This is useful if you want to provide your own scrollable component, remember however to make it an Animated component. (See: https://github.com/exponentjs/react-native-scrollable-mixin) (By default, returns a Animated.ScrollView with the given props)
renderStickyHeader	func	No	This renders an optional sticky header that will stick to the top of view when parallax header scrolls up.
stickyHeaderHeight	number	If renderStickyHeader is used	If renderStickyHeader is set, then its height must be specified.
contentContainerStyle	object	No	These styles will be applied to the scroll view content container which wraps all of the child views. (same as for ScrollView)
outputScaleValue	number	No	The value for the scale interpolation output value, default 5
