Ok, im fairly new to android but i have managed to teach myself the basics, i am making an app where you press a button , and a new screen opens and it shows a randomly generated number, the only problem is i dont know how to generate and display the random number, i have been searching the web for ages and have only found little snippets of information , that dosent really make sense to me. :/

If someone could help me , or even give me just a little bit of info that should guide me in the right direction it would be great
