TUGAS/UAS/MOBILE_PROGRAMMING

TUGAS UAS MOBILE PROGRAMMING
MEMBUAT APLIKASI TERKONEKSI DATABASE SQLITE PADA ANDROID STUDIO
"LIST GROUP KPOP"

 Assalamualaikum Wr. Wb

1. Deskripsi Project

Aplikasi List View "GROUP KPOP" saya buat untuk menampilkan daftar para member Group KPOP Boys & Girls, tidak lupa juga saya membuat menu login untuk masuk ke daftar listviewnya. Menu login pada aplikasi ini sudah terkoneksi dengan DatabaseSqlite. Tampilan login terdiri dari username, password, button login dan button register. Button login digunakan untuk masuk aplikasi dengan insert username dan password, sedangkan button register untuk mendaftarkan akun baru. Saya membuat 10 daftar nama group, yang mana ketika di klik salah satunya akan muncul penjelasan singkat mengenai latar belakang terbentuknya group tersebut beserta foto para membernya.
