AutocompleteTextView打印对象为字符串

Question

我正在使用带有自定义对象的ArrayAdapter，当我希望它显示字段时，自动完成文本视图将我的自定义对象打印为字符串。我以为我可以像这样覆盖我的过滤方法

@Override
public CharSequence convertResultToString(Object resultValue) {
    Tag result = (Tag) resultValue;
    return  result.getName();
}

这被调用，但似乎对显示的result4

没有影响

编辑过滤器类

Filter filter = new Filter() {
            @Override
            protected FilterResults performFiltering(CharSequence constraint) {
                FilterResults filterResults = new FilterResults();
                resultList.clear();
                if (constraint != null) {
                    Iterable<String> iterable = st.keysWithPrefix(constraint.toString());
                    Iterator<String> iterator = iterable.iterator();
                    while (iterator.hasNext()) {
                        String keys = iterator.next();
                        resultList.add(st.get(keys));
                    }
                    // Retrieve the autocomplete results.
                    filterResults.values = resultList;
                    filterResults.count = resultList.size();
                }
                return filterResults;
            }

            @Override
            public CharSequence convertResultToString(Object resultValue) {
                Tag result = (Tag) resultValue;
                return result.getName();
            }

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