How to randomized a group of images in imageview in android studio?

I'm a beginner on android development and I am creating a game like 4Pics1Word for my project. I'm wondering on how can I randomized the images by 4. Every activities must have 4 images and those images must be related to each other, thus, 4 pics 1 word. So I'm thinking I can put descriptions on each image and then randomized it then use a control statement in order to get those 4 pictures with matching descriptions. I only need to randomized it in order to randomized the levels (so each application will not have the same consecutive levels). Any ideas? Thank youuuu!
