一      日期拾取器

      1.在eclipse可视化界面上拖拽组件到布局中

    <DatePicker        android:id="@+id/datePicker1"        android:layout_width="wrap_content"        android:layout_height="wrap_content" />
      2.布局中获取日期组件
DatePicker dp = (DatePicker)findViewById(R.id.datePicker1);
      3.创建日历对象，获取当前的日历时间
        Calendar c = Calendar.getInstance();        int year = c.get(Calendar.YEAR);        int month = c.get(Calendar.MONTH);        int date = c.get(Calendar.DATE);
      4.初始化日期选择器，并且绑定监听器
        dp.init(year, month, date, new OnDateChangedListener() {                        @Override            public void onDateChanged(DatePicker arg0, int arg1, int arg2, int arg3) {                                Toast.makeText(MainActivity.this,                         MainActivity.this.year+ " " + MainActivity.this.month + " " + MainActivity.this.date,                        Toast.LENGTH_LONG).show();                            }        });
运行效果如下，事件监听方面：当点击日期后会有提示框显示
 
二      时间拾取器
1.在eclipse可视化界面上拖拽组件到布局中
    <TimePicker        android:id="@+id/timePicker1"        android:layout_width="wrap_content"        android:layout_height="wrap_content" />
2.布局中获取日期组件
TimePicker tp = (TimePicker)findViewById(R.id.timePicker1);
 
3.创建日历对象，获取当前的日历时间
        Calendar c = Calendar.getInstance();        hour = c.get(Calendar.HOUR);        munite = c.get(Calendar.MINUTE);        second = c.get(Calendar.SECOND);
4.绑定监听器
        tp.setOnTimeChangedListener(new OnTimeChangedListener() {                        @Override            public void onTimeChanged(TimePicker arg0, int arg1, int arg2) {                                                Toast.makeText(MainActivity.this,                        MainActivity.this.hour+ " " + MainActivity.this.munite + " " + MainActivity.this.second,                        Toast.LENGTH_LONG).show();            }        });
运行效果如下，点击时间选择之后会有提示框显示
