How to provide spacing between android Radio Buttons of Vertical orientation

Try using marginTop instead of padding. I would also reccoment using a style for that instead of setting the value manually to each item.

Try using the layout_margin attribute, it works similarly to padding, but may have the effect you want. You can use simply android:layout_margin="20dp" or you can set individual sides, like you can for padding (ex: android:layout_marginLeft="20dp").
