Recyclerview Listview ve gridview'in yerine kullanıbilecek View Holder pattern'i kullanan yeni bir komponent.
Bir View'e ihtiyaç olduğunda layoutu inflate eden yeni bir ViewHolder objesi oluşur ve referansı saklanır liste her scroll olduğunda
bu objeyi kullanır. Bu nedenle adı recyclerView'miş :)
Diğer bir ozelliği LayoutManager, listedeki itemların dizilişlerini belirliyor.
1.LinearLayoutManager, klasik ListView
2.GridLayoutManager, GridView
3.StaggerGridLayoutManager kademeli,sıralı listview
