"" : i.toString()); } lbl.setText(sb.toString()); private static String fromListToString(List<Integer> input) { StringBuilder sb = new StringBuilder(); for

I have achieved almost everything that I want apart from one thing: Moving the different texts and buttons to the position that I'd like them to be. Here is a picture edited in Photoshop describing how I would like it to be: The Lottery currently looks like this after you press the Play button: (As you can see the buttons get shifted to the right in order to make space for the text that is squished in to the left of the buttons) What I'm looking to achieve is for the buttons position to never move, and to put the text under
