Rodrigocs - 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

import ParallaxScrollView from 'react-native-parallax-scroll-view';
import CustomScrollView from 'custom-scroll-view'

const AnimatedCustomScrollView = Animated.createAnimatedComponent(CustomScrollView)

render() {
  return (
    <ParallaxScrollView
      backgroundColor="blue"
      contentBackgroundColor="pink"
      parallaxHeaderHeight={300}
      // renderScrollComponent={() => <Animated.View />}
      renderScrollComponent={() => <AnimatedCustomScrollView />}
      renderForeground={() => (
       <View style={{ height: 300, flex: 1, alignItems: 'center', justifyContent: 'center' }}>
          <Text>Hello World!</Text>
        </View>
      )}>
      <View style={{ height: 500 }}>
        <Text>Scroll me</Text>
      </View>
    </ParallaxScrollView>
  );
}

There are more examples in the examples folder.

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.

PropertyTypeRequiredDescription
backgroundColorstringNoThe color of the header background. Defaults to #000)
backgroundScrollSpeednumberNoThe speed factor that the background moves at relative to the foreground. Defaults to 5.
contentBackgroundColorstringNoThis is the background color of the content. (Defaults to '#fff')
fadeOutForegroundboolNoIf true, the foreground will fade out as the user scrolls up. (Defaults to true)
onChangeHeaderVisibilityfuncNoA 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.
