android之DatePickerDialog与TimePickerDialog的简单例子

private void showDatePickerDialog() {
    //获取当前日期
    Calendar cal= Calendar.getInstance();
    int year = cal.get(Calendar.YEAR);
    int month = cal.get(Calendar.MONTH);
    int day = cal.get(Calendar.DAY_OF_MONTH);
    //创建DatePickerDialog实例
    final DatePickerDialog pickerDialog = new DatePickerDialog(AddAppointmentActivity.this, new DatePickerDialog.OnDateSetListener() {
        @Override
        public void onDateSet(DatePicker view, int year, int month, int dayOfMonth) {
            int year_set = year;
            int month_set = month;
            int day_set = dayOfMonth;
        }
    }, year, month, day);
    //设置点击Dialog以外屏幕可取消设置
    pickerDialog.setCancelable(true);
    pickerDialog.setCanceledOnTouchOutside(true);
    //添加取消按钮到Dialog
    pickerDialog.setButton(DialogInterface.BUTTON_NEGATIVE, "取消", new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int which) {

        }
    });
    //显示Dialog
    pickerDialog.show();
}

private void showTimePickerDialog() {
    //获取当前时间
    long time = System.currentTimeMillis();
    Calendar calendar = Calendar.getInstance();
    calendar.setTimeInMillis(time);
    int minute = calendar.get(Calendar.MINUTE);
    int houtOfDay = calendar.get(Calendar.HOUR_OF_DAY);

    //
    final TimePickerDialog pickerDialog = new TimePickerDialog(AddAppointmentActivity.this, 0, new TimePickerDialog.OnTimeSetListener() {
        @Override
        public void onTimeSet(TimePicker view, int hourOfDay, int minute) {

        }
    },houtOfDay,minute,true);
    //设置点击Dialog以外屏幕可取消设置
    pickerDialog.setCancelable(true);
    pickerDialog.setCanceledOnTouchOutside(true);
    //添加取消按钮到Dialog
    pickerDialog.setButton(DialogInterface.BUTTON_NEGATIVE, "取消", new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int which) {

        }
    });
    //显示Dialog
    pickerDialog.show();
}
