[android-developers] Re: UI performance is slow on large screen tablet

Are you using the convert view parameter and getTag() with a
viewHolder or are you creating the elements in the list from scratch
each time?

Using the convert view reduces GC and removes the time to create new
objects for each row.

See this for an explanation:

I hope I'm not giving you stuff you already know, but this is an
important pattern to improve UI speed.
