Re: [android-developers] Custom Base Adapter.

Are you sure we're talking about Android here? What's wrong with Vector? ArrayList is good for most occasions but Vector has its merits...  you got it wrong regarding the SimpleAdapter anyhow (they use any implementation of List, which Vector is.. they dont need ArrayList... the description saying it needs an ArrayList is a mistake).

 

Vector isn't really dead...It can make things simple if you want to deal with concurrency easily.

Stack is also a subclass of it, so those should count as well :)

 

Also, how is Hashtable obsolete for android development? you got any better alternative for its purposes?  I think you're thinking of the C# classes which are rather obsolete replaced by Dictionary and List... but unless he's a Mono developer, he's using Java :)

It sounds like he may want to call Collections.sort() on the backing collection.  Probably a Vector.

Why do you say "probably" a 'Vector'? The standard Android classes that use a collection include 

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

that uses 'ArrayList', not 'Vector'. I was not able in a brief search to find anything in the Android docs 

that would lead a person to use 'Vector'.

It is striking to me how much pernicious life the 'Vector' class has even fifteen years after it was declared obsolete.

Ditto 'Hashtable' but somewhat less so.
