Step-1: Create a new react native project, if you don’t know how to create a new project in react native just follow this tutorial.

Step-2: Open index.android.js  / index.ios.js  in your favourite code editor and erase all code and follow this tutorial.

Step-3: Through react , react-native  packages import all required components.

import React, { Component } from "react";
import { Platform, StyleSheet, Text, View, Image, ScrollView} from "react-native";
Step-4 : Implement render method and return ScrollView component wrapped by root View component. This ScrollView component is horizontally allign and it consists of 10 Image component as child.
render() {

    let dimensions = Dimensions.get("window");
    let imageHeight = Math.round((dimensions.width * 9) / 16);
    let imageWidth = dimensions.width;

    return (
      <View style={styles.container}>

        <Text style={styles.headerText}>Horizontal ScrollView Example.</Text>

        <ScrollView horizontal={true}>

          <Image
            style={{ height: imageHeight, width: imageWidth }}
            source={require("./images/1.jpg")}
          />

          <Image
            style={{ height: imageHeight, width: imageWidth }}
            source={require("./images/2.jpg")}
          />

          <Image
            style={{ height: imageHeight, width: imageWidth }}
            source={require("./images/3.jpg")}
          />

          <Image
            style={{ height: imageHeight, width: imageWidth }}
            source={require("./images/4.jpg")}
          />

          <Image
            style={{ height: imageHeight, width: imageWidth }}
            source={require("./images/5.jpg")}
          />

          <Image
            style={{ height: imageHeight, width: imageWidth }}
            source={require("./images/6.jpg")}
          />

          <Image
            style={{ height: imageHeight, width: imageWidth }}
            source={require("./images/7.jpg")}
          />

          <Image
            style={{ height: imageHeight, width: imageWidth }}
            source={require("./images/8.jpg")}
          />

          <Image
            style={{ height: imageHeight, width: imageWidth }}
            source={require("./images/9.jpg")}
          />

          <Image
            style={{ height: imageHeight, width: imageWidth }}
            source={require("./images/10.jpg")}
          />
        </ScrollView>
      </View>
    );
  }

Step-5 : Apply the below style sheet design.
const styles = StyleSheet.create({
  container: {
    flex: 1,
    justifyContent: "center",
    backgroundColor: "#e5e5e5"
  },
  headerText: {
    fontSize: 20,
    textAlign: "center",
    margin: 10,
    fontWeight: "bold"
  },
});

Complete Source Code for App.js 

Lets see the complete source code that helps to create simple horizontal scroll view layout with the help of ScrollView Component in react native application.
/**
 * Sample React Native App
 * https://github.com/facebook/react-native
 * @flow
 */

import React, { Component } from "react";
import { Platform, StyleSheet, Text, View, Image, ScrollView, Dimensions } from "react-native";

export default class HomeActivity extends Component {
  render() {

    let dimensions = Dimensions.get("window");
    let imageHeight = Math.round((dimensions.width * 9) / 16);
    let imageWidth = dimensions.width;

    return (
      <View style={styles.container}>

        <Text style={styles.headerText}>Horizontal ScrollView Example.</Text>

        <ScrollView horizontal={true}>

          <Image
            style={{ height: imageHeight, width: imageWidth }}
            source={require("./images/1.jpg")}
          />

          <Image
            style={{ height: imageHeight, width: imageWidth }}
            source={require("./images/2.jpg")}
          />

          <Image
            style={{ height: imageHeight, width: imageWidth }}
            source={require("./images/3.jpg")}
          />

          <Image
            style={{ height: imageHeight, width: imageWidth }}
            source={require("./images/4.jpg")}
          />

          <Image
            style={{ height: imageHeight, width: imageWidth }}
            source={require("./images/5.jpg")}
          />

          <Image
            style={{ height: imageHeight, width: imageWidth }}
            source={require("./images/6.jpg")}
          />

          <Image
            style={{ height: imageHeight, width: imageWidth }}
            source={require("./images/7.jpg")}
          />

          <Image
            style={{ height: imageHeight, width: imageWidth }}
            source={require("./images/8.jpg")}
          />

          <Image
            style={{ height: imageHeight, width: imageWidth }}
            source={require("./images/9.jpg")}
          />

          <Image
            style={{ height: imageHeight, width: imageWidth }}
            source={require("./images/10.jpg")}
          />
        </ScrollView>
      </View>
    );
  }
}

const styles = StyleSheet.create({
  container: {
    flex: 1,
    justifyContent: "center",
    backgroundColor: "#e5e5e5"
  },
  headerText: {
    fontSize: 20,
