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.

You can use switch like this   XML Layout   lt RadioGroup             android id    id RG              android layout width  wrap content              android layout height  wrap content  gt                lt RadioButton                 android id    id R1                  android layout width  wrap contnet                  android layout height  wrap content                  android text  R1    gt                lt RadioButton                 android id    id R2                  android layout width  wrap contnet                  android layout height  wrap content                  android text  R2    gt   lt  RadioGroup gt    And JAVA Activity  switch  RG getCheckedRadioButtonId              case R id R1              regAuxiliar   ultimoRegistro          case R id R2              regAuxiliar   objRegistro          default              regAuxiliar   null     none selected         You will also need to implement an onClick function with button or setOnCheckedChangeListener function to get required functionality
