In an Android 2.1+ app I have a list of items belonging to categories. Clicking an item will perform a search for items in that item's category. Clicking a search result will repeat this action (i.e. show the same list). At any time, long clicking an item will open that item for editing/deletion. The rationale is that you will be adding and comparing items far more often than you should need to edit or delete existing items. However, seeing as nothing is gained by repeating a search I wonder if it would be reasonable/sensible to change the click behaviour to work like long clicks after a search has been performed, and either disable long click or find some other use for it in that context (like show a menu that lets you quickly delete an item), or if that would cause confusion.
I am aware that long click may be being phased out in favour of more obvious interaction. I feel the alternative would confuse interaction and/or crowd the interface and I'm not worried about users not being aware of long click, so I prefer to use that. However, if anyone has an opinion on my implementation versus always bringing up a context menu I'd like to hear it.
