Tugas 8 : Membuat Image Scroll

Tugas saya adalah membuat sebuah image scroll di Android Studio menggunakan Kotlin. Image scroll ini dilengkapi dengan fitur untuk menggulir melalui beberapa gambar yang ditampilkan pada layar perangkat Android. Pengguna dapat menggulir ke atas bawahuntuk melihat gambar yang berbeda. Melalui Kotlin, saya akan mengimplementasikan logika untuk mengontrol interaksi antara pengguna dan image scroll, serta memperbarui tampilan layar dengan gambar-gambar yang relevan. Tujuannya adalah menciptakan pengalaman pengguna yang lebih interaktif dan menarik dengan memudahkan navigasi melalui koleksi gambar pada aplikasi Android.
