            // text = s.toLowerCase(Locale.getDefault());
            mDisplayedValues = new ArrayList<SelectedAthleteDEtail>();
            mDisplayedValues.clear();
            if (text.length() == 0) {
                 mDisplayedValues = AthleteData;
               // mDisplayedValues.addAll(AthleteData);
                BoardRecyclerData.setAdapter(adapter);
                notifyDataSetChanged();
            } else {
                mDisplayedValues.clear();
                notifyDataSetChanged();
                for (SelectedAthleteDEtail cs : AthleteData) {
                         if (cs.getFirstName().toLowerCase().contains(text)) {
                          mDisplayedValues.add(cs);
                             Log.d(TAG, "filterab: "+cs.getFirstName());
                             Log.d(TAG, "filterxyz: "+mDisplayedValues);
                        }
                    }
