Hi, Kristopher is correct. Actually i wanted to display images one by one randomly.
I tried with random but doesn't work. but I was able to do that by using Array List and shuffle.collections. first I added max number of images into array list and shuffled it. Then I got shuffled numbers one by one. Thank you everyone for helping me.
