To create each radio button option, create a RadioButton in your layout. However, because radio buttons are mutually exclusive, you must group them together inside a RadioGroup . By grouping them together, the system ensures that only one radio button can be selected at a time.
Only one radio button in a group can be selected at the same time. Note: The radio group must have share the same name (the value of the name attribute) to be treated as a group.
A RadioGroup class is used for set of radio buttons. If we check one radio button that belongs to a radio group, it automatically unchecks any previously checked radio button within the same group.
You group radio buttons by drawing them inside a container such as a Panel control, a GroupBox control, or a form. All radio buttons that are added directly to a form become one group. To add separate groups, you must place them inside panels or group boxes.

public void oneRadioButtonClicked(View view) {
// Is the button now checked?
boolean checked = ((RadioButton) view).isChecked();
switch(view.getId()) {
case R.id.radio_one0Id:
if (checked)
one = "0";
break;
case R.id.radio_one5Id:
if (checked)
one = "5";
break;
case R.id.radio_one10Id:
if (checked)
one = "10";
break;
case R.id.radio_one20Id:
if (checked)
one = "20";
break;
case R.id.radio_one35Id:
if (checked)
one = "35";
break;
case R.id.radio_one50Id:
if (checked)
one = "50";
break;
case R.id.radio_one65Id:
if (checked)
one = "65";
break;
case R.id.radio_one75Id:
if (checked)
one = "75";
break;
case R.id.radio_one85Id:
if (checked)
one = "85";
break;
case R.id.radio_one95Id:
if (checked)
one = "95";
