How to check which segmented control is selected?

[pinloop]

If I create a segmented control with 3 radiobuttons?. How can I check what box is selected?

if android:id="@+id/button1" is selected = do this
if android:id="@+id/button2" is selected = do that

Tips?

int checkedRadioButtonId = radioGroup.getCheckedRadioButtonId();
if (checkedRadioButtonId == -1) {
    // No item selected
}
else{
    if (checkedRadioButtonId == R.id.radio_button1) {
        // Do something with the button
    }
}
