适配器的内容已更改，但ListView未收到通知

Question

我一直在运行android 5的三星手机上遇到java.lang.IllegalStateException异常。它只发生在运行android 5（API 21）的三星手机上。

我的Logcat说明如下：

 Fatal Exception: java.lang.IllegalStateException: The content of the
 adapter has changed but ListView did not receive a notification. Make
 sure the content of your adapter is not modified from a background
 thread, but only from the UI thread. Make sure your adapter calls
 notifyDataSetChanged() when its content changes. [in ListView(-1,
 class android.widget.ListPopupWindow$DropDownListView) with
 Adapter(classcom.commandsoftware.androidbookingapp.Activity.Fragments.PlacesAPIFragment.AutoCompleteSearch$GooglePlacesAutocompleteAdapter)]

我的适配器代码如下所示：

  class GooglePlacesAutocompleteAdapter extends ArrayAdapter implements Filterable {
        private ArrayList resultList;

        public GooglePlacesAutocompleteAdapter(Context context) {
            super(context, R.layout.autocomplete_list_item);
        }

        @Override
        public int getCount() {
            if (resultList != null) {
                return resultList.size();
            } else {
                return 0;
            }
        }

        @Override
        public Object getItem(int index) {
            return resultList.get(index);
        }

        @Override
        public Filter getFilter() {
            return new Filter() {
                @Override
                protected FilterResults performFiltering(CharSequence constraint) {
                    FilterResults filterResults = new FilterResults();
                    if (constraint != null) {
                        resultList = autocomplete(constraint.toString());
                        filterResults.values = resultList;
                        if (resultList != null) {
                            filterResults.count = resultList.size();
                        } else {
                            filterResults.count = 0;
                        }
                    }
                    return filterResults;
                }

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

任何帮助都会很棒。我已经在SO上尝试过最受欢迎的答案，但没有一个能帮上忙。

我的直觉告诉我，这与这些行有关

 if (results != null && results.count > 0) {
  notifyDataSetChanged();
  } else {
 notifyDataSetInvalidated();
}
