kali ini saya akan membuat program Canteen menggunakan Android Studio.
Tanpa berlama-lama, langsung saja kita ke code.
- Deskripsi Aplikasi 
- Pertama kali membuka aplikasi, kita akan ditunjukkan tampilan login.
- Masukkan username "admin" dan password "123" untuk masuk ke dalam aplikasi
- Setelah masuk, akan muncul tampilan All Warung yang mana bisa dilihat 4 warung yang tersedia. Klik warung pertama.
- Setelah mengklik warung pertama, akan muncul list menu yang ada di warung 1. Pilih jumlah menu yang akan kita pesan, kemudian tekan teks bayar.
- Setelah mengklik tulisan bayar, akan muncul summary menu yang kita pilih beserta total harganya. Masukkan nominal bayar kemudian tekan tombol pay.
- Akan muncul list menu yang kita bayar, beserta total, nominal dan kembalian. Klik tombol back untuk kembali ke menu all warung.
- Dalam tampilan all warung, tekan tombol logout untuk kembali ke menu login.
- Source Code Aplikasi
Berikut source code aplikasi saya :
