HorizontalScrollView in Kotlin

In Android ScrollView allows multiple views that are places within the parent view group to be scrolled. Scrolling in the android application can be done in two ways either Vertically or Horizontally.

In this article, we will be discussing how to create a Horizontal ScrollView in Kotlin .

XML Attributes	Description
android:fillViewport	It defines whether the horizontal scrollview should stretch its content to fill the viewport.
android:layout_height	Sets the height of the horizontal scroll view
android:layout_width	Sets the width of the horizontal scroll view
android:src	Sets background of the image
android:id	Sets unique id of the view

Let’s start by first creating a project in Android Studio. To do so, follow these instructions:

First step is to create a new Project in Android Studio. For this follow these steps:

• Click on File, then New and then New Project and give name whatever you like
• Then, select Kotlin language Support and click next button.
• Select minimum SDK, whatever you need
• Select Empty activity and then click finish.

Modify activity_main.xml file

<?xml version="1.0" encoding="utf-8"?>
<HorizontalScrollView
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="match_parent"
        android:layout_height="match_parent">

    <LinearLayout
            android:layout_width="200dp"
            android:layout_height="200dp"
            android:layout_marginTop="20dp"
            android:orientation="horizontal">


        <ImageView
                android:id="@+id/image1"
                android:layout_width="200dp"
                android:layout_height="200dp"
                android:layout_marginRight="20dp"
                android:src="@mipmap/image1"/>

        <ImageView
                android:id="@+id/image2"
                android:layout_width="200dp"
                android:layout_height="200dp"
                android:layout_marginRight="20dp"
                android:src="@mipmap/image2"/>

        <ImageView
                android:id="@+id/image3"
                android:layout_width="200dp"
                android:layout_height="200dp"
                android:layout_marginRight="20dp"
                android:src="@mipmap/image3"/>

        <ImageView
                android:id="@+id/image4"
                android:layout_width="200dp"
                android:layout_height="200dp"
                android:layout_marginRight="20dp"
                android:src="@mipmap/image4"/>


    </LinearLayout>
</HorizontalScrollView>

Add Images

We need to add some images which can be used for scrolling purpose. So, we have to copy the images from our local computer path to app/res/mipmap folder.

Note: We have added the images to mipmap folder instead of drawable folder because the size of the images is very large.

Create HorizontalScrollView in MainActivity.kt file

Open app/src/main/java/yourPackageName/MainActivity.kt and do the following changes:

package com.geeksforgeeks.myfirstKotlinapp

import androidx.appcompat.app.AppCompatActivity
import android.os.Bundle

class MainActivity : AppCompatActivity() {

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)
    }
}

AndroidManifest.xml file

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
          package="i.apps.hscrollview">

    <application
            android:allowBackup="true"
            android:icon="@mipmap/ic_launcher"
            android:label="@string/app_name"
            android:roundIcon="@mipmap/ic_launcher_round"
            android:supportsRtl="true"
            android:theme="@style/AppTheme">
        <activity android:name=".MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN"/>

                <category android:name="android.intent.category.LAUNCHER"/>
            </intent-filter>
        </activity>
    </application>

</manifest>

Run as Emulator:
