Java Autocompletetextview不显示带有自定义适配器的下拉列表

我有一个自动完成文本视图。我正在从API获取结果，并将结果发送到textchanged上的适配器

这是适配器。

public class ProductSearchAdapter extends BaseAdapter implements Filterable {

    private Context context;
    private ArrayList<ProductListModel> originalList;
    private ArrayList<ProductListModel> suggestions = new ArrayList<>();
    private Filter filter = new CustomFilter();


    public ProductSearchAdapter(Context context, ArrayList<ProductListModel> originalList) {
        this.context = context;
        this.originalList = originalList;
    }

    @Override
    public int getCount() {
        return suggestions.size(); // Return the size of the suggestions list.
    }

    @Override
    public Object getItem(int position) {
        return originalList.get(position).getName();
    }


    @Override
    public long getItemId(int position) {
        return 0;
    }

    /**
     * This is where you inflate the layout and also where you set what you want to display.
     * Here we also implement a View Holder in order to recycle the views.
     */
    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        LayoutInflater inflater = LayoutInflater.from(context);

        ViewHolder holder;

        if (convertView == null) {
            convertView = inflater.inflate(R.layout.product_search_row, parent, false);
            holder = new ViewHolder();

            holder.textViewProductName = (TextView) convertView.findViewById(R.id.textViewProductName);
            holder.imageViewProductImage = (ImageView) convertView.findViewById(R.id.imageViewProductImage);

            convertView.setTag(holder);
        } else {
            holder = (ViewHolder) convertView.getTag();
        }

        holder.textViewProductName.setText(originalList.get(position).getName());
        Picasso.with(context)
                .load(originalList.get(position).getImagesSmall().get(0).getSrc())
                .into(holder.imageViewProductImage);


        return convertView;
    }


    @Override
    public Filter getFilter() {
        return filter;
    }

    private static class ViewHolder {
        ImageView imageViewProductImage;
        TextView textViewProductName;
    }

    /**
     * Our Custom Filter Class.
     */
    private class CustomFilter extends Filter {
        @Override
        protected FilterResults performFiltering(CharSequence constraint) {
            suggestions.clear();

            if (originalList != null && constraint != null) { // Check if the Original List and Constraint aren't null.
                for (int i = 0; i < originalList.size(); i++) {
                    if (originalList.get(i).getName().toLowerCase().contains(constraint)) { // Compare item in original list if it contains constraints.
                        suggestions.add(originalList.get(i)); // If TRUE add item in Suggestions.
                    }
                }
            }
            FilterResults results = new FilterResults(); // Create new Filter Results and return this to publishResults;
            results.values = suggestions;
            results.count = suggestions.size();

            return results;
        }

        @Override
        protected void publishResults(CharSequence constraint, FilterResults results) {
            if (results.count > 0) {
                notifyDataSetChanged();
            } else {
                notifyDataSetInvalidated();
            }
        }
    }
}

关于API响应：

autoCompleteTextViewSearch.addTextChangedListener(new TextWatcher() {
            @Override
            public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) {

            }

            @Override
            public void onTextChanged(CharSequence charSequence, int i, int i1, int i2) {
                if (charSequence.toString().length() > 0) {
                    hitSearchAPI(charSequence.toString());
                }
            }

            @Override
            public void afterTextChanged(Editable editable) {

使用阵列适配器时使用相同的文本视图，但不使用自定义适配器

产品列表模型：
