标签: android-parsequeryadapter

当我在片段中使用ParseQueryAdapter来检索数据并将错误传递给微调器时,我在我的应用程序中使用Parse.com

java.lang.IllegalArgumentException: Spinner adapter view type count must be 1

和申请停止.但是,如果我尝试使用ArrayAdapter,它可以工作.可能是什么问题呢？

ParseQueryAdapter代码:

ParseQueryAdapter.QueryFactory<ParseObject> spnQuery=
            new ParseQueryAdapter.QueryFactory<ParseObject>() {
                public ParseQuery create() {
                    ParseQuery query = new ParseQuery(tableName);
                    return query;
                }
            };
    ParseQueryAdapter<ParseObject> adapter = new ParseQueryAdapter<ParseObject>(getActivity().getApplicationContext(), spnQuery);
    adapter.setTextKey(columnName);
    spnLecture.setAdapter(adapter);
