单个弹出窗口中的Date和TimePicker

我是android的新手。我试图用timepicker创建一个datepicker对话框。我通过做一些研究来做到这一点。

这是我的代码

dataandTime.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            DatePickerDialog dpd = new DatePickerDialog(context,
                    mDateSetListener, myear, mmonth, mday);
            dpd.show();
        }
    });

private DatePickerDialog.OnDateSetListener mDateSetListener = new 
        DatePickerDialog.OnDateSetListener() {
            @Override
            public void onDateSet(DatePicker view, int year, int monthOfYear,
                    int dayOfMonth) {
                TimePickerDialog tpd = new TimePickerDialog(context, mTimeSetListener, mhour, mminute, false);
                tpd.show();
                myear=year;
                mmonth=monthOfYear;
                mday=dayOfMonth;
                nextdate = (new StringBuilder().append(myear).append("-")
                        .append(mmonth + 1).append("-").append(mday).append(" ")).toString();
            }
        };

        private OnTimeSetListener mTimeSetListener = new TimePickerDialog.OnTimeSetListener() {
            @Override
            public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
                // TODO Auto-generated method stub
                mhour = hourOfDay;
                mminute = minute;
                nexttime = (new StringBuilder().append(mhour).append(":").append(mminute).append(":").append(msecond)).toString();
                dateandtime = nextdate+nexttime;
            }
        };

我正在将日期值提供给nextdate，将时间值提供给nexttime。在那之后我连接了两个值，并且我分配了dateandtime。现在我想获得像2014-12-08 12:22:58这样的日期和时间值。有人可以指导我吗？提前谢谢。

阅读此链接http://developer.android.com/reference/java/text/SimpleDateFormat.html

您需要的模式可能是：yyyy-MM-dd HH:mm:ss

使用它像：

SimpleDateFormat fmt = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
Date date = fmt.parse(dateString);

在单个对话框中尝试使用它，日期和时间
