. Jika ada pertanyaan bisa diskusi dengan saya via email di 
. Jadi buat siapapun yang berminat belajar pengolahan citra bisa unduh ni ebook secara gratis hehe. Tapi jangan dijual looo 
. karena it’s for non commercial use only. jadi tunggu apalagi deh yang butuh download klik aja link dibawah.
. Kenapa sih kita tidak gunakan fitur bawaan layout Horizontal Scroll View saja? sebenarnya bukan masalah sih, cuman ya gitu pertama kalo hobi masang masang tag XML ga masalah sih, sekarang pada contoh diatas yang pakai 2 halaman aja tagnya kaya gitu panjang. gimana kalo 5 halaman, 10 halaman atau bahkan 20 halaman (lebay kaleee 
). Selain itu yang kedua setiap xml layout jumlah viewnya terbatas. jadi kalo misalnya lebih dari 80 Views biasanya sih ga mau jalan. Ga percaya? coba aja sendiri 
. wkwkwkwkwk
) nah jadi next post kita akan mencoba bagaimana membuat scroller view secara horizontal dengan ViewPager. So Keep Update ya 
. Keuntungan dari menyimpan image di cache adalah ketika kita membuat app yang butuh melakukan penyimpanan gambar atau app yang meload gambar berulang ulang akan menjadi lebih efisien. Image yang sudah di load tidak perlu didownload kembali, itung itung hemat kuota
