问题 I am currently trying, in addition of the amazing ActionBerSherlock library to add a spinner navigation menu in my application (like Google Maps) Note: I have been thinking also about the SPotify/Evernote/Facebook pattern, but that seems inappropriate on Android: http://alexanderblom.se/2012/04/23/android-navigation-and-spotify/ I have already worked on the spinner (http://developer.android.com/design/building-blocks/spinners.html), but adding an icon seems not so easy Thank a lot for any

问题 Like this one, I've seen a few how-to's on this site, but truthfully, I'm not really getting it . I want one spinner's content to be based upon a previous spinner selection, like in a States and Cities scenario. In general terms, what is the workflow?
