React Native | ScrollView Component

Hello React Friends,

In this blog, we will learn about the ScrollView component of React Native.

ScrollView is a core component in React Native that enables scrolling functionality for both horizontal and vertical directions. It allows users to view content that extends beyond the screen dimensions, making it essential for building user interfaces with dynamic and large content. Whether it’s a list of items, a form, or a detailed view, ScrollView facilitates smooth vertical or horizontal scrolling, ensuring that users can navigate through the entirety of the content effortlessly.

ScrollView props:

ScrollView component provides various props to customize its behavior and appearance. Some of the commonly used props include:

contentContainerStyle: 

This prop allows you to apply styles to the content container of the ScrollView. You can use it to control the padding, margin, alignment, and other styles of the content within the scroll view.

horizontal:

If set to true, the scroll view will scroll horizontally instead of vertically.

showsHorizontalScrollIndicator:

If set to true, a horizontal scroll indicator will be displayed to indicate the position of the content within the scroll view.

showsVerticalScrollIndicator: 

If set to true, a vertical scroll indicator will be displayed to indicate the position of the content within the scroll view.

onScroll:

This prop allows you to specify a function that will be called when the scroll position of the ScrollView changes. The function receives an event object containing information about the scroll event, such as the current scroll position.

scrollEnabled: 

If set to false, scrolling will be disabled for the ScrollView.

scrollEventThrottle:

This prop controls how often the onScroll event will be fired while scrolling. It specifies the minimum time between each event in milliseconds.

pagingEnabled: 

If set to true, the ScrollView will snap to each page while scrolling, similar to a paging behavior.

keyboardDismissMode:

Determines whether the keyboard should be dismissed when scrolling. Possible values are “none”, “on-drag”, and “interactive”.

refreshControl:

This prop allows you to add a pull-to-refresh control to the ScrollView. You can pass a RefreshControl component to enable this feature.

Example of React Native ScrollView Component:

import React from 'react';
import { View, ScrollView, Text, StyleSheet } from 'react-native';

const ScrollViewExample = () => {
return (
    <View style={styles.container}>
      <ScrollView contentContainerStyle={styles.scrollViewContent}>
        <Text style={styles.text}>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Ut vehicula lectus id nisi blandit, non tempus nulla blandit. Integer et dapibus dolor. Duis sed tortor quis justo fermentum efficitur.</Text>
        <Text style={styles.text}>Sed sagittis varius massa, et fringilla ligula lacinia sit amet. Cras ultricies lectus sit amet ligula finibus, eget aliquam odio suscipit. Sed fermentum posuere nisi, sit amet gravida justo vehicula vitae. Vestibulum gravida efficitur erat, ac pellentesque nulla tristique vitae.</Text>
        <Text style={styles.text}>Praesent vel turpis suscipit, iaculis metus non, aliquet quam. Nullam porttitor ultricies erat, sit amet feugiat nisl tincidunt eu. Sed vehicula, libero nec finibus consectetur, dolor libero vehicula nisi, et suscipit odio sapien vel lectus. Duis eget nunc nec velit euismod rhoncus. Morbi vel arcu sem. </Text>
      </ScrollView>
    </View>
  );
}
const styles = StyleSheet.create({
  container: {
    flex: 1,
    padding: 20,
    justifyContent: 'center',
    alignItems: 'center',
  },
  scrollViewContent: {
    paddingVertical: 20,
  },
  text: {
    fontSize: 16,
    marginBottom: 10,
  },
});
export default ScrollViewExample;
