In Android ScrollView incorporates multiple views within itself and allows them to be scrolled.

- Select Empty activity and then click finish.
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.
We will be needing some images to be used in application. You can use the images that you like but the images need to be copied from our local computer path to app/res/drawable folder.
Create Scroll View in MainActivity.kt file
Open app/src/main/java/yourPackageName/MainActivity.kt. In this file, we declare a variable ScrollView to create the Scroll View widget like this:
