A LinearLayout is made to display one item next to the other, therefore it's not the best choice here.

The easy way is a Gridlayout, which is specifically made to display items in a grid.

For the case that you have lots of Radiobuttons, you could use a Recyclerview with a GridlayoutManager, too, but i guess that's overkill.

You might also try a ConstraintLayout together with Flow to keep your view-hierarchy shallow and scale well on differently-wide devices.

One final word: Use xml wherever you can instead of inflating views, it makes live so much easier. (Does not apply to compose)
