Releasing memory of a ListView on Android

Question

I've got a ListView with a custom adapter that extends an ArrayAdapter. Each item in the ListView is an ImageView.

The ListView is a menu that is mostly hidden, but is loaded on startup - it takes a HUDE amount of memory.

I'd like it to populate only when it is shown, and to be released when it is hidden (which will hinder performance, but release memory I guess).

How can this be done? Any other ideas to make ListView use the memory better?

Thanks

As @Raghunandan said about ViewHolder , you should implement the same. That will save from creating uncessary objects and will make your ListView scrolling smooth.
