雖然旋轉設備上一課onActivityCreated（）總是調用

我是新來的android.I有一個問題。我使用fragments.My應用程序有5個選項卡。我的應用程序意外停止後，一個特定的選項卡，然後移動到另一個選項卡，並旋轉當前視圖。通過調試我得到了錯誤。錯誤是，當旋轉當前視圖控制去上一課的onActivtyCreated（）。雖然旋轉設備上一課onActivityCreated（）總是調用

datetext.setText（TimeFormater.FormatDate（dateString））;

該行給出空指針異常。控件總是轉到下面給出的代碼。

public class ScheduleDailyView extends SherlockFragment{public void onActivityCreated(Bundle savedInstanceState) { 
    super.onActivityCreated(savedInstanceState); 
    nextbutn = (Button)getActivity().findViewById(R.id.buttonnext); 
    prebutn = (Button)getActivity().findViewById(R.id.buttonpre); 
    listview = (ListView)getActivity().findViewById(R.id.lv_schedule_listView); 
    datetext = (TextView)getActivity().findViewById(R.id.textscheduleviewdate); 
    dateString = TimeFormater.DateToString(Schedule.currentDate.getTime()); 
    ArrayList<ViewScheduleDTO> scheduleList =scheduleDaily.readschedules(dateString,doctor_id); 
    datetext.setText(TimeFormater.FormatDate(dateString)); 
    rowitems = scheduleDaily.getScheduleRowList(dateString,scheduleList); 
    listview.setAdapter(new ScheduleCustomView(appContext, rowitems)); 
    if(userType.equals(UserTypeEnum.Admin.getDisplayName()) || userType.equals(UserTypeEnum.Doctor.getDisplayName())) 
     listview.setOnItemLongClickListener(this); 
    listview.setOnItemClickListener(this); 
    nextbutn.setOnClickListener(this); 
    prebutn.setOnClickListener(this); 
}}

您確定datetext存在於佈局中嗎？ –

Ya datetext – jithin

嘗試......在你的manifest.xml

<activity android:name="Your Activity Name" 
      android:configChanges="keyboard|keyboardHidden|orientation|screenLayout|uiMode|screenSize|smallestScreenSize" android:windowSoftInputMode="adjustPan"/>
