Hi All,
Please find the code below

private RadioGroup radioGroup1;
private RadioButton radioGenderButton;

public void HUP1() {

radioGroup1 = (RadioGroup) findViewById(R.id.radioGender);

        // get selected radio button from radioGroup
int selectedId = radioGroup1.getCheckedRadioButtonId();

// find the radiobutton by returned id
        radioGenderButton = (RadioButton) findViewById(selectedId);

Toast.makeText(MyAndroidAppActivity.this, radioGenderButton.getText(), Toast.LENGTH_SHORT).show();


  }
