Assalamualaikum, kali ini saya akan mencoba berbagi kepada teman-teman mengenai aplikasi sederhana "Kalkulator".

Aplikasi sederhana ini berfungsi untuk mengetahui nilai yang sudah di tambah, kurang, kali, dan bagi yang sudah ditentukan oleh pengguna. Pengguna tinggal memasukan angka nilai.

Berikut adalah penjelasan mengenai cara membuat aplikasi.

Buat tampilan seperti gambar dibawah ini:

Dalam pembuatan aplikasi sederhana ini digunakan beberapa komponen yang terdiri dari:

• Text View
• Edit Text
• Button
• List View

Berikut adalah source code nya.
