dont Forget to add Run time permission for write external storage

Thanks, but I do not understand, your asnwer not showing date and time. only record video source. — chohyunwook, Jan 12 '17 at 05:45
You can get the current time using any one of these answers http://stackoverflow.com/questions/5369682/get-current-time-and-date-on-android . Then place a view over your video at desired location and display time on it — Manohar, Jan 12 '17 at 05:57
I try this. when I before record button click camera preview screen, show current time. over video preview. but record file not showing current time. — chohyunwook, Jan 12 '17 at 06:18
i have an idea but its not good practise, just switch on the camera place time over the view and do screen recording instead of video recording — Manohar, Jan 12 '17 at 06:45
