c)         调用Activity的 showDialog()方法显示对话框

public class MainActivity extends Activity {

   private Button b1,b2;
   private TextView tv1,tv2;
   private Calendar c;
   private int m_year,m_month,m_day;
   private int m_hour,m_minute;

    public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.main);

        b1 = (Button)findViewById(R.id.Button01);
        b2 = (Button)findViewById(R.id.Button02);

        c = Calendar.getInstance();

        m_year = c.get(Calendar.YEAR);
        m_month = c.get(Calendar.MONTH);
        m_day = c.get(Calendar.DAY_OF_MONTH);
        m_hour = c.get(Calendar.HOUR);
        m_minute = c.get(Calendar.MINUTE);

        tv1 = (TextView)findViewById(R.id.TextView01);
        tv1.setText(m_year+":"+(m_month+1)+":"+m_day);
        tv2 = (TextView)findViewById(R.id.TextView02);
        tv2.setText(m_hour+":"+m_minute);

        b1.setOnClickListener(new OnClickListener() {

                 public void onClick(View v) {

                        showDialog(0);
                 }
          });

        b2.setOnClickListener(new OnClickListener() {

                 public void onClick(View v) {
                        showDialog(1);
                 }
          });

    }

    protected Dialog onCreateDialog(int id) {

       if(id==0)
              return new DatePickerDialog(this,l1,m_year, m_month, m_day);
       else
              return new TimePickerDialog(this,l2, m_hour, m_minute, false);

    }

    private OnDateSetListener  l1 = new OnDateSetListener() {

          public void onDateSet(DatePicker view, int year, int monthOfYear,

                        int dayOfMonth) {

                 m_year = year;
                 m_month = monthOfYear;
                 m_day = dayOfMonth;
                 tv1.setText(m_year+":"+(m_month+1)+":"+m_day);

          }

   };

   private OnTimeSetListener  l2 = new OnTimeSetListener() {

          public void onTimeSet(TimePicker view, int hourOfDay, int minute) {

                 m_hour = hourOfDay;
                 m_minute = minute;
                 tv2.setText(m_hour+":"+m_minute);
          }
   };
}
