Android: RadioButton within Nested Layout under RadioGroup falls out of Group

Question

I'm trying to get some sensible positioning of my radiobuttons which are part of a RadioGroup. I was having trouble as my RadioGroup was sitting on top of the rest of my layout design, then I use margins to push the buttons around, the problem here is this works on one or two device layouts only. I thought I struck gold when I discovered I could define my RadioGroup then put in a RelativeLayout below which amongst other things contained one of the RadioButtons, then I repeat twice more. this gives me the layout I desire. Problem is, when I run the code, the RadioButtons act link standalone buttons :(

So two questions,

• can I link these buttons back to the Group?

• Is there a decent way to be able to define the layout of the RadioGroup Radiobuttons independently of the Group.

I am thinking an alternative may be independent RadioButtons and use code to enable/disable them, but that does kind of defeat the usefulness of RadioGroup.

thanks.

Here is my XML layout should you be curious.

Answer 1

After looking around for a solution it looks the only way to do this is to use individual radio buttons and then programmically control there on/off states.
