Android中的Timepicker中的Stackoverflow錯誤？

Question

上午使用時間選擇器通過對話框片段。在那個時間選擇器設置最小和最大time.i時，我得到了堆棧溢出錯誤，當我點擊減號（現在的時間以分鐘爲單位的最小值）按鈕分鐘時間選擇器API 10，但在API 15中，其工作fine.am無法得到解決這個問題。任何人都知道可以幫助我解決這個問題。

要調用updateTime(hours, minutes);從onTimeChanged時validTime==false。這是你無限循環的根本原因。我不知道爲什麼它適用於API 15（可能是你從來沒有在API 15到達此行）

嘗試這樣的事情。

@Override 
public Dialog onCreateDialog(Bundle savedInstanceState) { 

    TimePickerDialog _time = new TimePickerDialog(getActivity(), ontimeSet, hours, minutes,false){ 
     private boolean ignoreChange = false; 

     @Override 
     public void onTimeChanged(TimePicker view, int hourOfDay, int minute) { 
      if(ignoreChange) return; 
      try{ 
       boolean validTime; 
       if(hourOfDay < minHour) { 
        validTime = false; 
       } 
       else if(hourOfDay == minHour) { 
        validTime = minute >= minMinute; 
       } 
       else if(hourOfDay == maxHour) { 
        validTime = minute <= maxMinute; 
       } 
       else { 
        validTime = true; 
       } 

       if(validTime) { 
        hours = hourOfDay; 
        minutes = minute; 
       } 
       else { 
        try{ 
         ignoreChange = true; 
         updateTime(hours, minutes); 
        }finally{ 
         ignoreChange = false; 
        } 
       } 

      }catch(Exception e){ 
       Log.e(TAG,"Error onTimeChanged",e); 
      } 
     } 
    }; 
    return _time; 
}
