getActivity() inside viewholder

getActivity() only works in fragments. A view will have activity Context. So get Context from the view.

Change

startActivity(new Intent(getActivity(), TicketDetails.class));

to

Context context = view.getContext();
context.startActivity(new Intent(context, TicketDetails.class));
