删除getItemView（）中的项后，notifyDataSetChanged（）刷新ListView

Question

我有一个扩展ParseQueryAdapter的适配器。我想删除函数getItemView()中的一个项目，所以我打电话给：

public View getItemView(final AlertObject alertObject, View view, final ViewGroup parent) {

... // Some conditions
    alertObject.deleteInBackground(new DeleteCallback() {
        @Override
        public void done(ParseException e) {
            if(e == null) {
                notifyDataSetChanged();
            } else {
                LogUtils.e(LogUtils.getTag(), e.getMessage());
            }
        }
    });
...

}

但是，删除项目后ListView不会刷新。我做错了什么？

修改

Adapter和ListView之间的映射完成如下：

ParseQueryAdapter.QueryFactory<AlertObject> factory =
        new ParseQueryAdapter.QueryFactory<AlertObject>() {
            public ParseQuery<AlertObject> create() {
                ParseQuery<AlertObject> query = AlertObject.getQuery();
                query.orderByDescending(AlertObject.TIMESTAMP_KEY);
                query.fromLocalDatastore();
                return query;
            }
        };

alertsListAdapter = new AlertListItemAdapter(activity, factory);
alertsListView = (ListView) rootView.findViewById(R.id.alerts_list_view);
alertsListView.setAdapter(alertsListAdapter);

替代解决方案

目前我正在使用替代解决方案，即在删除后刷新片段：

((MainActivity)context).getFragmentManager().beginTransaction()
    .detach(listAlertsFragment)
    .attach(listAlertsFragment)
    .commit();
