RadioGroup radioGroup;

RadioButton radioButton;

String mSelectedRadioButton=“”;

radioGroup = findViewById(R.id.radioGroup);

            radioButton_hot = findViewById(selectedId);

            mSelectedRadioButton = radioButton_hot.getText().toString();

            break;

        case R.id.radioButton_warm:

            selectedId = group.getCheckedRadioButtonId();

            radioButton_warm = findViewById(selectedId);

            break;
