Dynamic ScrollView in Kotlin

Last Updated : 12 Jul, 2025

In Android, ScrollView incorporates multiple views within itself and allows them to be scrolled. In this article we will be discussing how to programmatically create a Scroll view in Kotlin.

Step by Step Implementation

Step 1: Create a new project

To create a new project in Android Studio please refer to How to Create/Start a New Project in Android Studio.

Step 2: Modify activity_main.xml file

Second step is to design our layout page. Here, we will use the LinearLayout to get the Scroll View from the Kotlin file.

activity_main.xml:

XML

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout 
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:id="@+id/main"
    android:gravity="center"
    android:orientation="vertical"
    tools:context=".MainActivity">

</LinearLayout>

Step 3: Create Scroll View in MainActivity.kt file

Open app > src > main > java > {package-name} > MainActivity.kt. In this file, we declare a variable ScrollView to create the Scroll View widget like this:

val scrollView = ScrollView(this)
val layoutParams = LinearLayout.LayoutParams(
        ViewGroup.LayoutParams.MATCH_PARENT, 
        ViewGroup.LayoutParams.MATCH_PARENT
)
scrollView.layoutParams = layoutParams

then add the widget in layout using this

linearLayout.addView(scrollView)

MainActivity.kt:

Kotlin

package org.geeksforgeeks.demo

import android.os.Bundle
import androidx.appcompat.app.AppCompatActivity
import android.view.Gravity
import android.view.ViewGroup
import android.widget.ImageView
import android.widget.LinearLayout
import android.widget.ScrollView

class MainActivity : AppCompatActivity() {

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

        val scrollView = ScrollView(this)
        val scrollParams = LinearLayout.LayoutParams(
            ViewGroup.LayoutParams.MATCH_PARENT,
            ViewGroup.LayoutParams.MATCH_PARENT)
        scrollView.layoutParams = scrollParams

        val linearLayout = LinearLayout(this)
        val linearParams = LinearLayout.LayoutParams(
            ViewGroup.LayoutParams.MATCH_PARENT,
            ViewGroup.LayoutParams.WRAP_CONTENT)
        linearLayout.orientation = LinearLayout.VERTICAL
        linearLayout.layoutParams = linearParams

        scrollView.addView(linearLayout)

        val params =LinearLayout.LayoutParams(
            ViewGroup.LayoutParams.MATCH_PARENT,
            ViewGroup.LayoutParams.WRAP_CONTENT
        )
        params.setMargins(32, 32, 32, 32)

        val imageView1 = ImageView(this)
        imageView1.setLayoutParams(params)
        imageView1.scaleType = ImageView.ScaleType.CENTER_CROP
        imageView1.setImageResource(R.drawable.k1)
        linearLayout.addView(imageView1)

        val imageView2 = ImageView(this)
        imageView2.setLayoutParams(params)
        imageView2.scaleType = ImageView.ScaleType.CENTER_CROP
        imageView2.setImageResource(R.drawable.k2)
        linearLayout.addView(imageView2)

        val imageView3 = ImageView(this)
        imageView3.setLayoutParams(params)
        imageView3.scaleType = ImageView.ScaleType.CENTER_CROP
        imageView3.setImageResource(R.drawable.k3)
        linearLayout.addView(imageView3)

        val imageView4 = ImageView(this)
        imageView4.setLayoutParams(params)
        imageView4.scaleType = ImageView.ScaleType.CENTER_CROP
        imageView4.setImageResource(R.drawable.k4)
        linearLayout.addView(imageView4)

        val root: LinearLayout = findViewById(R.id.main)
        root.addView(scrollView)
    }
}
