DatePicker和TimePicker的使用

?

datePicker.init(datePicker.getYear(), datePicker.getMonth(), datePicker.getDayOfMonth(), new OnDateChangedListener(){public void onDateChanged(DatePicker view, int year,int monthOfYear, int dayOfMonth) {updateTextView();}});//时间选择器有监听器可以直接使用timePicker.setOnTimeChangedListener(new OnTimeChangedListener() {public void onTimeChanged(TimePicker view, int hourOfDay, int minute) {updateTextView();}});public void updateTextView(){Calendar calendar = Calendar.getInstance();calendar.set(datePicker.getYear(), datePicker.getMonth(), datePicker.getDayOfMonth(),timePicker.getCurrentHour(), timePicker.getCurrentMinute());SimpleDateFormat sdf = new SimpleDateFormat("yyyy 年 MM 月 dd 日     HH:mm");tvShowTime.setText(sdf.format(calendar.getTime()));}

不知道为什么DatePicker不设置一个setOnTimeChangedListener呢？
