android - Populate AlertDialog With Values -
i new programming , started android development out of passion , second application.
i looked android tutorials online , trying this: 1. record button in mainaactivity 2. on-click opens dialog box gives options record. 3. dialog box has 4 buttons (start, stop, playback, stop playback).
what working: 1. on click shows dialog box, no options in it. 2. record works, when played different activity.
i believe have missed something, can help?
