Get method documentation [Android Documentation]

Returns the current iconified state of the SearchView.

Set method documentation [Android Documentation]

Iconifies or expands the SearchView. Any query text is cleared when iconified. This is a temporary state and does not override the default iconified state set by SearchView.SetIconifiedByDefault(bool). If the default state is iconified, then a false here will only be valid until the user closes the field. And if the default state is expanded, then a true here will only clear the text field and not close it.
