Contoh Coding Membuat Objek Android Pemrograman Grafis pada Java

Membuat objek Android di pemrograman grafis tidak semudah membuat objek di photoshop. Di pemrograman grafis Anda harus paham mengenai koordinat-koordinat karena koordinatlah yang penting untuk membuat sebuah objek.

Coding membuat objek android pemrograman grafis pada java terdiri dari 2 files java, yaitu : Android.java dan Objek.java. Kedua files java tersebut harus berada dalam 1 source packages.

Tanpa panjang lebar lagi. Silahkan Anda coba coding membuat objek android ini. Admin harap hasilnya sama seperti yang Anda inginkan.
