Must is a strong word. You are used to desktop file selectors, where in most cases they are just a pop-up dialogs. However in mobile it makes more sense for the file selector to occupy as much screen as possible. Otherwise you will end up with a dialog that in landscape mode displays max 3 files and browsing involves lots of fast (i.e. inacurate) scrolling. Please also mind, that mouse pointer in desktop environment is 1px. With touch screen we are talking pointers 5 x 5 px all the way up to 20 x 20 in high res sreens. That is not to say that file selector would not work as a dialog. It would most likely require some very neat and clever UI tricks. Feel free to innovate and implement one. When done right, people will write articles about it. -- Daniel Drozdzewski -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
