如何过滤适配器类中的确切数据

Question

我正在通过编辑文本搜索来自服务的数据，但搜索没有在每次搜索时正确完成，其过滤错误的数据和一些时间列表数据在我的布局中添加了多次，任何人都可以帮助我。

过滤类

private class ItemFilter extends Filter {

    @Override
    protected FilterResults performFiltering(CharSequence constraint) {
        FilterResults results = new FilterResults();        // Holds the results of a filtering operation in values
        ArrayList<CountriesModel> FilteredArrList = new ArrayList<CountriesModel>();

        if (mOriginalValues == null) {
            mOriginalValues = new ArrayList<CountriesModel>(ArrayListModel); // saves the original data in mOriginalValues
        }


        if (constraint == null || constraint.length() == 0) {

            // set the Original result to return
            results.count = mOriginalValues.size();
            results.values = mOriginalValues;
        } else {
            constraint = constraint.toString().toLowerCase();
            for (int i = 0; i < mOriginalValues.size(); i++) {
                String data = mOriginalValues.get(i).getCountry_name();
                if (data.toLowerCase().startsWith(constraint.toString())) {
                    FilteredArrList.add(new CountriesModel());
                }
            }
            // set the Filtered result to return
            results.count = FilteredArrList.size();
            results.values = FilteredArrList;
        }
        return results;
    }



    @SuppressWarnings("unchecked")
    @Override
    protected void publishResults(CharSequence constraint, FilterResults results) {
        ArrayListModel = (ArrayList<CountriesModel>) results.values;
        notifyDataSetChanged();
    }



}

}

片段：

        EditTextSearch.addTextChangedListener(new TextWatcher() {
            @Override
            public void beforeTextChanged(CharSequence s, int start, int count, int after) {
                Log.e( "Databe  ", s.toString());
            }

            @Override
            public void onTextChanged(CharSequence s, int start, int before, int count) {
                // String txt=  EditTextSearch.getText().toString();
                Log.e( "Dataon  ", s.toString());
                adapter.getFilter().filter(s.toString());

            }

            @Override
            public void afterTextChanged(Editable s) {

                       /*String txt=  EditTextSearch.getText().toString();
                  */
                Log.e( "Dataaf  ", s.toString());
                  /*  String text = EditTextSearch.getText().toString().toLowerCase(Locale.getDefault());
                    adapter.getFilter().filter(text);*/
            }
        });
