日期和時間戳單彈出

我是新來的android。只是我試圖用timepicker創建一個datepicker對話框。我通過做一些研究來做到這一點。日期和時間戳單彈出

這是我的代碼

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'獲取日期值nextdate和時間值nexttime。之後，我將這兩個值連接起來，並將其分配給dateandtime。現在我想獲得像2014-12-08 12:22:58 dateandtime值。任何人都可以請指導我？提前致謝。

閱讀此鏈接http://developer.android.com/reference/java/text/SimpleDateFormat.html

也許你需要的模式是這樣的：yyyy-MM-dd HH:mm:ss

這樣使用它：

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