APLIKASI PENCATAT KEUANGAN HARIAN

Pada kali ini saya akan membagikan tentang aplikasi pencatat keuangan yang saya buat, yaitu "DOMPETQU" aplikasi ini berbasis di android KITKAT keatas. jika di intsall di bawah minimum spek android tidak akan bisa.

oke langsung saja kita lihat aplikasi nya.

SPLASH SCREEN

splash

yang pertama adalah tampilan awal saat kita membuka aplikasi seperti gambar di atas. tampilan akan muncul selama 4 detik. lalu akan pindah otomatis ke halaman utama.

HALAMAN UTAMA

tampilan awal

Pada Tampilan awal kita akan menemukan 4 nama dan 4 kolom isi lalu di tambah dengan 4 tombol yang berfungsi SIMPAN,LIHAT,UBAH dan HAPUS.

jika kita mengisi kolom yang tersedia dan menekan tombol SIMPAN makan akan berhasil dan keluar notifokasi "berhasil KAKA"

lalu jika kita ingin melihat hasil, maka akan keluar seperti.

tampil data

namun jika kita ingin merubah data nya. isi kan "ID" yang tertera di hasil lalu pilih yang ingin di ubah dan tekan lagi tombol UBAH. maka akan berubah seperti ini.

ubah data

Ubah data berhasil. lanjut untuk menghapus data. Cara nya sama yaitu dengan mengisi kan "ID" yang ingin di hapus, lalu tekan tombol hapus makan akan jadi seperti ini.

hapus data

Aplikasi yang saya buat ini menggunakan SQLITE android yang dimana memakai CRUD sebagai navigasi nya.
