I have three images stored in a table class called: "events" and table column called: "image" on Parse.com
I used two queries 1 to handle the displaying of the images and one to get another table's information (Those are all Strings)
THE PROBLEM IS: The query that i used to get all the images only displays one of the three images in the RecyclerView instead of all three.
How can i display all three images from Parse.com inside a RecyclerView?
