android:datePicker与timePicker学习记录

datePicker控件通过添加监听器onDateChangedListener()来监听datePicker的年月日的改变，timePick控件通过监听器onTimeChangerListener()来监听tiemPicker的年月日的改变。

如何获取时间：

Calendar c = Calendar.getInstance();
        year = c.get(Calendar.YEAR);
        month = c.get(Calendar.MONTH);
        day = c.get(Calendar.DAY_OF_MONTH);
        hour = c.get(Calendar.HOUR_OF_DAY);
        minute = c.get(Calendar.MINUTE);

timePicker用法类似。
