I'm developing an Android application that presents the user with a search form, then presents a list of matching results after the query has been submitted. The results will be displayed on a separate screen.
The preferred design pattern in Android is to place "Submit" and other important actions into the Action Bar, which is a dedicated menu area typically displayed at the top of the screen:
Which type of icon should I use to represent "Submit" in this menu? I found a few possibile candidates (the three shown here are Android system icons from the Iconography guide), but I'm not sure about any of them. Is there a generally accepted icon for this or is nearly anything a reasonable choice because of the context?
