  RadioButton r;
  r.setOnCheckedChangeListener(listener){

 @Override
 public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
 // add your dialog here
}

}

YOu follow the link to get to know about the date picker: http://www.androidpeople.com/android-datepicker-dialog-example

you just have to replace the button date to the radio button, note the id used in the button should be same as that in the radio button.
