How can you randomly open an imageView by clicking on another imageview?

i want to program an android game where you have different imageViews in the View. By clicking on a button, different pictures should randomly be assigned to the Images on the view. after that you Click on one of the Images on the view and the randomly assigned Image should Open. I want to program all of this with the visibilites but i also Need a random Instruction with all the Images. But you can't put Images in an array, so how can i solve this program? I Know it's very hard to Understate my Problem, but still i'll be very thankful for your help
