Ios 在spark列表表单sqlite数据库中显示数据

在这里，我想在从sqlite数据库获取的列表中显示多个项目：

protected function fetchfalseanswerquestion():void
            {
                sqlConnection = new SQLConnection();
                sqlConnection.open(File.applicationStorageDirectory.resolvePath("SchoolSeries.db"));
                var stmt:SQLStatement = new SQLStatement();
                stmt.sqlConnection = sqlConnection;
                stmt.text = "select * from Schoolseries_Exam_Mode_User_Answers where Result = 'False'";
                stmt.execute();
                var result11:SQLResult = stmt.getResult();
                DataModel.getInstance().connection = sqlConnection;
                                    listquestion.visible = true;
                listquestion.dataProvider = new ArrayCollection(result11.data[0].data);
            }

在按钮上单击“我呼叫列表”功能：

protected function showrecord_clickHandler(event:MouseEvent):void
            {
                // TODO Auto-generated method stub
                fetchfalseanswerquestion();             
            }

从sqlite数据库获取数据的函数：

protected function fetchfalseanswerquestion():void
            {
                sqlConnection = new SQLConnection();
                sqlConnection.open(File.applicationStorageDirectory.resolvePath("SchoolSeries.db"));
                var stmt:SQLStatement = new SQLStatement();
                stmt.sqlConnection = sqlConnection;
                stmt.text = "select * from Schoolseries_Exam_Mode_User_Answers where Result = 'False'";
                stmt.execute();
                var result11:SQLResult = stmt.getResult();
                DataModel.getInstance().connection = sqlConnection;
                                    listquestion.visible = true;
                listquestion.dataProvider = new ArrayCollection(result11.data[0].data);
            }

这里是我的按钮控件和列表控件：

<s:Button id="showrecord" click="showrecord_clickHandler(event)">

</s:Button>

<s:List id="listquestion" visible="false" height="300" width="300" labelField="Fk_Question_Description">



</s:List>

但是，当我运行此程序时，不会出现错误，但不会显示任何内容

欢迎在代码中提供任何帮助/建议。

听起来您的ArrayCollection是空的。您确定SQL返回任何结果吗？在验证ArrayCollection不是空的之后，您应该确认从SQLite返回的数据中的每一行都有一个名为“Fk_Question_Description”的字段。完全无关：您可能需要考虑使用<代码> SqLo连接.OpenActhCy]（）/代码>异步执行所有数据库操作，这样您的UI在执行查询时不会被锁定。
