Listview 필터(검색기능)이 오류는 없는데 실행이안되요 도움좀

Question

public void addItem(String content, String startyear, String startmonth, String startdate,

                    String startampm, String starthour, String startminute, String finishyear,
                    String finishmonth, String finishdate, String finishampm, String finishhour,
                    String finishminute){
    ContentListViewItem item = new ContentListViewItem();
    item.setContent(content);
    item.setStart_year(startyear);
    item.setStart_month(startmonth);
    item.setStart_date(startdate);
    item.setStart_ampm(startampm);
    item.setStart_hour(starthour);
    item.setStart_minute(startminute);
    item.setFinish_year(finishyear);
    item.setFinish_month(finishmonth);
    item.setFinish_date(finishdate);
    item.setFinish_ampm(finishampm);
    item.setFinish_hour(finishhour);
    item.setFinish_minute(finishminute);



    listViewItemList.add(item);
    notifyDataSetChanged();

adapte additem으로 넣어주고

@Override
public Filter getFilter() {
    if(listFilter == null){
        listFilter = new ListFilter();
    }
    return listFilter;
}
class ListFilter extends android.widget.Filter {
    @Override
    protected FilterResults performFiltering(CharSequence constraint) {
        FilterResults results = new FilterResults();

        if(constraint == null || constraint.length() == 0){
            results.values = listViewItemList;
            results.count = listViewItemList.size();
        } else {
            ArrayList<ContentListViewItem> itmeList = new ArrayList<ContentListViewItem>();

            for(ContentListViewItem item : listViewItemList) {
                if(item.getContent().toUpperCase().contains(constraint.toString().toUpperCase()));
                {
                    itmeList.add(item);
                }
            }
            results.values = itmeList;
            results.count = itmeList.size();
        }
        return results;
    }

    @Override
    protected void publishResults(CharSequence constraint, FilterResults results) {
        filterdeItemList = (ArrayList<ContentListViewItem>) results.values;

        if(results.count > 0){
            notifyDataSetChanged();
        } else {
            notifyDataSetChanged();
        }
    }

필터를하려고 다른 코드 참조해서 작성

public interface Comparatorinter<ContentListViewItem> {
        String compare(ContentListViewItem o1, ContentListViewItem o2);
}

필터 인터페이스입니다.

EditText Edit_search = (EditText)view.findViewById(R.id.Edit_search);
Edit_search.addTextChangedListener(new TextWatcher() {
    @Override
    public void beforeTextChanged(CharSequence s, int start, int count, int after) {

    }

    @Override
    public void onTextChanged(CharSequence s, int start, int before, int count) {

    }

    @Override
    public void afterTextChanged(Editable edit) {
        String filterText = edit.toString();
        ((ContentListViewAdapter)listview.getAdapter()).getFilter().filter(filterText);

    }
});

메인함수의 필터하는 부분입니다.
