How to add a radio group to radio buttons inside of a table?

Question

I have multiple radio buttons which I want to layout using a table but also include them in a single radio group. I have the following xml layout:

Answer 1

rg1 = (RadioGroup)findViewById(R.id.radioGroup1);
        rg2 = (RadioGroup)findViewById(R.id.radioGroup2);
        rg1.setOnCheckedChangeListener(this);
        rg2.setOnCheckedChangeListener(this);
    }
    boolean rg1b = false;
    boolean rg2b = false;

    @Override
    public void onCheckedChanged(RadioGroup rgId, int radioButtonId) {
        switch (rgId.getId()) {
        case R.id.radioGroup1:
            rg1b=true;
            if(rg2b)
                rg2.clearCheck();
            break;

        case R.id.radioGroup2:
            rg1b=true;
            if(rg1b)
                rg1.clearCheck();
            break;
        }
