DatePicker和TimePicker的用法

xml布局：

 1 <?xml version="1.0" encoding="utf-8"?>
 2 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
 3   android:layout_width="fill_parent"
 4   android:layout_height="fill_parent"
 5   android:orientation="vertical" >
 6  
 7   <TextView
 8     android:id="@+id/textView1"
 9     android:layout_width="wrap_content"
10     android:layout_height="wrap_content"
11     android:text="请选择购买本书的具体时间" />
12  
13   <DatePicker
14     android:id="@+id/datePicker"
15     android:layout_width="wrap_content"
16     android:layout_height="wrap_content"
17     android:layout_gravity="center_horizontal" />
18  
19   <TimePicker
20     android:id="@+id/timePicker"
21     android:layout_width="wrap_content"
22     android:layout_height="wrap_content"
23     android:layout_gravity="center_horizontal" />
24  
25   <EditText
26     android:id="@+id/show"
27     android:layout_width="wrap_content"
28     android:layout_height="wrap_content"
29     android:cursorVisible="false"
30     android:editable="false" />
31  
32 </LinearLayout>

Java代码：

 1 public class AndroidDemo5Activity extends Activity {
 2  
 3  // 记录当前的时间
 4  private int year;
 5  private int month;
 6  private int day;
 7  private int hour;
 8  private int minute;
 9  
10  @Override
11  protected void onCreate(Bundle savedInstanceState) {
12  // TODO Auto-generated method stub
13  super.onCreate(savedInstanceState);
14  setContentView(R.layout.main);
15  DatePicker date = (DatePicker) findViewById(R.id.datePicker);
16  TimePicker time = (TimePicker) findViewById(R.id.timePicker);
17  // 或许当前的年月日，小时，分钟
18  Calendar ca = Calendar.getInstance();
19  year = ca.get(Calendar.YEAR);
20  month = ca.get(Calendar.MONTH);
21  day = ca.get(Calendar.DAY_OF_MONTH);
22  hour = ca.get(Calendar.HOUR);
23  minute = ca.get(Calendar.MINUTE);
24  
25  // 初始化DatePicker
26  date.init(year, month, day, new OnDateChangedListener() {
27  
28   @Override
29   public void onDateChanged(DatePicker arg0, int year, int month,
30    int day) {
31   AndroidDemo5Activity.this.year = year;
32   AndroidDemo5Activity.this.month = month;
33   AndroidDemo5Activity.this.day = day;
34   // 显示当前时间和日期
35   showDate(year, month, day, hour, minute);
36   }
37  
38  });
39  
40  // 为TimerPicker指定事件监听器
41  time.setOnTimeChangedListener(new OnTimeChangedListener() {
42  
43   @Override
44   public void onTimeChanged(TimePicker arg0, int hour, int minute) {
45   AndroidDemo5Activity.this.hour = hour;
46   AndroidDemo5Activity.this.minute = minute;
47   }
48  });
49  }
50  
51  protected void showDate(int year2, int month2, int day2, int hour2,
52   int minute2) {
53  EditText text = (EditText) findViewById(R.id.show);
54  text.setText("您的购买时间为：" + year2 + "年" + month2 + "月" + day2 + "日"
55   + hour2 + "时" + minute2 + "分");
56  
57  }
58 }
