无法从字典API检索过滤的数据

Question

我的代码某处有问题，我无法从字典API检索数据，因此我的应用程序是dic，因此在搜索视图中键入单词，应该检索提交单词的数据，但是我没有得到任何结果

@Override
public boolean onCreateOptionsMenu(Menu menu) {

    MenuInflater inflater = getMenuInflater();

    inflater.inflate(R.menu.settingmenu,menu);

    MenuItem item = menu.findItem(R.id.search);

    SearchView searchView = (SearchView)item.getActionView();

    searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
        @Override
        public boolean onQueryTextSubmit(String query) {
            return false;
        }

        @Override
        public boolean onQueryTextChange(String newText) {

            adapter.getFilter().filter(newText);

            return true;
        }
    });
    return true;
}

private Filter filertaki = new Filter() {

    @Override
    protected FilterResults performFiltering(CharSequence constraint) {

        ArrayList<modelclass> arrayListiiii  = new ArrayList<>();

        if(constraint == null || constraint.length() == 0) {
           arrayListiiii.addAll(arrayListfull);
        } else {
            String filerpattern 

             arrayListiiii.toString().toLowerCase().trim();

            for(modelclass item : arrayListiiii) {
               if(item.getWord().toLowerCase().contains(filerpattern)) {
                   arrayListiiii.add(item);
               }
            }
        }

        FilterResults results = new FilterResults();

        results.values = arrayListiiii;

        return results;
    }

    @Override
    protected void publishResults(CharSequence constraint, FilterResults results) {
         arrayListfull.clear();

         arrayListfull.addAll((ArrayList)results.values);

         notifyDataSetChanged();
    }
};
