java.lang.IllegalStateException：在創建日期選擇器對話框時活動已被破壞

我想從我的主Activity使用DialogFragments創建一個DatePicker對話框。我已經擴展了DialogFragment類，並返回新datePickerDialog按java.lang.IllegalStateException：在創建日期選擇器對話框時活動已被破壞

http://developer.android.com/guide/topics/ui/controls/pickers.html

這裏是我的類代碼：

import java.util.Calendar; 
import android.app.DatePickerDialog; 
import android.app.DatePickerDialog.OnDateSetListener; 
import android.app.Dialog; 
import android.app.DialogFragment; 
import android.os.Bundle; 
import android.widget.DatePicker; 

public class DatePickerFragment extends DialogFragment implements OnDateSetListener{ 

    @Override 
    public void onDateSet(DatePicker arg0, int arg1, int arg2, int arg3) { 
     // TODO set the date for the alarm  
    } 

    @Override 
    public Dialog onCreateDialog(Bundle savedInstanceState){ 
     //set current date as default date 
     final Calendar c = Calendar.getInstance(); 
     int year = c.get(Calendar.YEAR); 
     int month = c.get(Calendar.MONTH); 
     int day = c.get(Calendar.DAY_OF_MONTH); 

     //Create New Instance of the datepicker dialog 
     return new DatePickerDialog(getActivity(), this, year, month, day); 
    } 

}

我對主Acivity一個按鈕來觸發對話框：

public void setAlarm(View view){ 
     //TextView reminder_title = (TextView) view.findViewById(R.id.reminder_title); 
     DialogFragment dateFragment = new DatePickerFragment(); 
     dateFragment.show(getFragmentManager(), "date picker"); 
    }

但是，當我嘗試點擊按鈕時，我得到一個「java.lang.IllegalStateException：Activity has been destroyed」異常在bel流線：

dateFragment.show(getFragmentManager(), "date picker");

這裏的活動日誌：

嘿感謝，這使得它完全清楚。 – flamesavor

你爲什麼刪除我的答案是正確的？ –

嗨，對不起，這是我的錯誤。鏈接有幫助，但沒有解決問題。我仍在尋找解決方案。 – flamesavor

今天面臨着類似的問題。這很簡單。只是檢查我的按鈕點擊以下：

if (!datePickerDialog.isAdded()) { 

      datePickerDialog.setStartDate(year, month, day); 
      datePickerDialog.show(getFragmentManager(), DATEPICKER_TAG); 
} 
else 
{ 
    //you can replace or add,,ur wish 
}

就是這樣
