android - Difference between Adapter and ArrayAdapter -


in android programming, have basic concept adapter , arrayadapter. understand arrayadapter used following link :

http://developer.android.com/reference/android/widget/arrayadapter.html

and understand adapter used following link :

http://developer.android.com/reference/android/widget/adapter.html

unfortunately, i'm new in android programming, i'm little bit confused concept (about relationship, main purpose , difference).

its arrayadapter derived adapter? if can explain it, great helpful. , sorry bad english :)

adapter interface, pretty provides skeleton framework of class implements it.

in case, (abstract) baseadapter class implements adapter , arrayadapter extends baseadapter (you can think of adapter arrayadapters grandparent).

here's more information on interfaces: http://docs.oracle.com/javase/tutorial/java/concepts/interface.html

the difference between interface , abstract class can confusing @ first here's helpful question: interface vs abstract class (general oo)
