You can also maintain a flag value based on listener,

 radioButton.setOnCheckedChangeListener(new OnCheckedChangeListener() {

            public void onCheckedChanged(CompoundButton arg0, boolean arg1) {

                //handle the boolean flag here. 
                  if(arg1==true)
                         //Do something

                else 
                    //do something else

            }
        });

Or simply isChecked() can also be used to check the state of your RadioButton.

Here is a link to a sample,

And then based on the flag you can execute your function.
