先来看看效果图吧：

下面来贴出代码吧，其中main.xml代码为：

其中java代码为：

public class AndroidDemo5Activity extends Activity {	// 记录当前的时间	private int year;	private int month;	private int day;	private int hour;	private int minute;	@Override	protected void onCreate(Bundle savedInstanceState) {		// TODO Auto-generated method stub		super.onCreate(savedInstanceState);		setContentView(R.layout.main);		DatePicker date = (DatePicker) findViewById(R.id.datePicker);		TimePicker time = (TimePicker) findViewById(R.id.timePicker);		// 或许当前的年月日，小时，分钟		Calendar ca = Calendar.getInstance();		year = ca.get(Calendar.YEAR);		month = ca.get(Calendar.MONTH);		day = ca.get(Calendar.DAY_OF_MONTH);		hour = ca.get(Calendar.HOUR);		minute = ca.get(Calendar.MINUTE);		// 初始化DatePicker		date.init(year, month, day, new OnDateChangedListener() {			@Override			public void onDateChanged(DatePicker arg0, int year, int month,					int day) {				AndroidDemo5Activity.this.year = year;				AndroidDemo5Activity.this.month = month;				AndroidDemo5Activity.this.day = day;				// 显示当前时间和日期				showDate(year, month, day, hour, minute);			}		});		// 为TimerPicker指定事件监听器		time.setOnTimeChangedListener(new OnTimeChangedListener() {			@Override			public void onTimeChanged(TimePicker arg0, int hour, int minute) {				AndroidDemo5Activity.this.hour = hour;				AndroidDemo5Activity.this.minute = minute;			}		});	}	protected void showDate(int year2, int month2, int day2, int hour2,			int minute2) {		EditText text = (EditText) findViewById(R.id.show);		text.setText("您的购买时间为：" + year2 + "年" + month2 + "月" + day2 + "日"				+ hour2 + "时" + minute2 + "分");	}}
