我有一个从日期选择器获取日期的程序，还需要从单选按钮组中选择客舱。我知道我的错误在于单选按钮侦听器，也许我没有把它放在正确的位置。请记住，我是新来的！谢谢！
public class Main extends Activity {
private int currentYear;
private int currentMonth;

super.onCreate(savedInstanceState);
setContentView(R.layout.main);
btDate = (Button)findViewById(R.id.btnDate);
reservation = (TextView)findViewById(R.id.txtReservation);
btDate.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
showDialog(DATE_DIALOG_ID);
