Disable Radio Button once selected?

Question

I have two radio buttons on my current page and need to disable the one that is selected so that it cannot be selected a second time. Can I add something before the break to disable the button.

switch(view.getId()){
            case R.id.radioButton:
                if(checked)
                    txt.setText(kmToM(dist));

                break;
            case R.id.radioButton2:
                if(checked)
                    txt.setText(mToK(dist));
                break;
        }

加上这个

$(YOUR_RADIO).attr("disabled","disabled");
