Error en Spinner en una ventana emergente, se bloquea cuando se hace clic

Tengo un PopupWindow que se llama de un fragmento y todo funciona excepto mi Spinner. Cuando hago clic en mi Spinner se bloquea y da el error:

"Android.view.WindowManager $ BadTokenException: No se puede agregar la ventana – token android.view.ViewRootImpl$W@421a46d8 no es válida, ¿es tu actividad en ejecución?"

• ¿Cómo actualizar dinámicamente un spinner?
• Uso de entryValues ​​con el elemento Spinner
• Mostrar para establecer la posición de popup?
• Cómo ocultar spinner dropdown android
• Android Cómo recuperar el valor de Spinner añadido dinámicamente

Mi código para llamar a la ventana emergente en el fragmento:

ManagerPopUp mManagerPopUp = new ManagerPopUp(getActivity()); mManagerPopUp.showPopUpAddEvent(); 

Mi código en ManagerPopUp para mostrar Popup:

 public class ManagerPopUp { private static final String TAG = "PopUpManager"; private Context mContext; public ManagerPopUp(Context mContext){ this.mContext = mContext; } public PopupWindow showPopUpAddEvent(){ final PopupWindow popUp = new PopupWindow(mContext); LayoutInflater inflater = (LayoutInflater)mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE); View layout = inflater.inflate(R.layout.popup_add_event, null); //Code for popup event TextView txtRoom, txtTitle, txtEnd, txtStart; ToggleButton tgRepeateWeekly, tgAddReminder; Button btConfirme, btCancel; txtTitle = (TextView)layout.findViewById(R.id.txt_lesson_title_event); txtRoom = (TextView)layout.findViewById(R.id.txt_lesson_room_event); txtStart = (TextView)layout.findViewById(R.id.txt_lesson_start_hour_event); txtEnd = (TextView)layout.findViewById(R.id.txt_lesson_end_hour_event); final Spinner spSelectCalendar = (Spinner)layout.findViewById(R.id.sp_select_calendar); Spinner spSelectReminder = (Spinner)layout.findViewById(R.id.sp_select_reminder_time); tgRepeateWeekly = (ToggleButton)layout.findViewById(R.id.tg_repeate_weekly); tgAddReminder = (ToggleButton)layout.findViewById(R.id.tg_add_reminder); btConfirme = (Button)layout.findViewById(R.id.bt_confirme); btCancel = (Button)layout.findViewById(R.id.bt_cancel); /************************************************************************************************************** * * Initializations * ***************************************************************************************************************/ HandlerCalendarProvider mCalendarProvider = new HandlerCalendarProvider(mContext); final ArrayList<ClassCalendar> mCalendarsList = mCalendarProvider.getAllCalendars(); AdapterCalendarSpinner mAdapterCalendarSpinner = new AdapterCalendarSpinner(mContext, mCalendarsList); spSelectCalendar.setAdapter(mAdapterCalendarSpinner); popUp.setContentView(layout); popUp.setWidth(LinearLayout.LayoutParams.MATCH_PARENT); popUp.setHeight(LinearLayout.LayoutParams.MATCH_PARENT); popUp.setFocusable(true); // Some offset to align the popup a bit to the left, and a bit down, relative to button's position. popUp.setBackgroundDrawable(new BitmapDrawable(mContext.getResources(), BitmapFactory.decodeResource(mContext.getResources(), R.color.color_popup_background))); //PopUpBackground popUp.showAtLocation(layout, Gravity.NO_GRAVITY, 0 , 0); return popUp; } } 

Mi adaptador de spinner:

 public class AdapterCalendarSpinner extends BaseAdapter implements SpinnerAdapter { private Context mContext; private ArrayList<ClassCalendar> mCalendarsList; public AdapterCalendarSpinner(Context mContext, ArrayList<ClassCalendar> mCalendarsList) { this.mContext = mContext; this.mCalendarsList = mCalendarsList; } @Override public int getCount() { return mCalendarsList.size(); } @Override public ClassCalendar getItem(int position) { return mCalendarsList.get(position); } @Override public long getItemId(int position) { return position; } @Override public View getView(int position, View convertView, ViewGroup parent) { ClassCalendar o = mCalendarsList.get(position); LayoutInflater vi = (LayoutInflater)mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE); convertView = vi.inflate(R.layout.sp_item_calendar_selected, null); LinearLayout llCalColor = (LinearLayout)convertView.findViewById(R.id.ll_calendar_selected_color); TextView txtCalName = (TextView)convertView.findViewById(R.id.txt_calendar_selected_name); TextView txtCalEmail = (TextView)convertView.findViewById(R.id.txt_calendar_selected_email); llCalColor.setBackgroundColor(o.getCalColor()); txtCalName.setText(o.getCalName()); txtCalEmail.setText(o.getCalEmail()); txtCalName.setTextColor(Color.WHITE); txtCalEmail.setTextColor(Color.WHITE); return convertView; } @Override public View getDropDownView(int position, View convertView, ViewGroup parent) { ClassCalendar o = mCalendarsList.get(position); LayoutInflater vi = (LayoutInflater)mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE); convertView = vi.inflate(R.layout.sp_item_calendar, null); //convertView = LayoutInflater.from(mContext).inflate(R.layout.sp_item_calendar, null); LinearLayout llCalColor = (LinearLayout)convertView.findViewById(R.id.ll_calendar_color); TextView txtCalName = (TextView)convertView.findViewById(R.id.txt_calendar_name); TextView txtCalEmail = (TextView)convertView.findViewById(R.id.txt_calendar_email); llCalColor.setBackgroundColor(o.getCalColor()); txtCalName.setText(o.getCalName()); txtCalEmail.setText(o.getCalEmail()); return convertView; } }
