sqlite + flex 4.6 +陣列疑惑

Question

這裏是一個flex新手。 我已經從

Connecting Flex to SQLite

測試的回答2'的代碼，但我修改它：扔在一個按鈕，它的目的是填充數據的列表中，被點擊後;結果是成功的，在列表中取回了「[object Object]」而不是數據;如何克服這個問題？ Flex是4.6，代碼如下：

<?xml version="1.0" encoding="utf-8"?> 
<s:View xmlns:fx="http://ns.adobe.com/mxml/2009" 
    xmlns:s="library://ns.adobe.com/flex/spark" 
    title=""> 
<fx:Declarations> 
    <!-- Place non-visual elements (e.g., services, value objects) here --> 
</fx:Declarations> 
<s:layout> 
    <s:VerticalLayout paddingTop="10" paddingLeft="10"/> 
</s:layout> 
<fx:Script> 

    <![CDATA[ 
     import flash.data.SQLConnection; 
     import flash.data.SQLStatement; 
     import flash.filesystem.File; 
     import flash.filesystem.FileMode; 

     import mx.collections.ArrayCollection; 
     private function getData():ArrayCollection 
     { 
      var stmt:SQLStatement = new SQLStatement(); 
      stmt.sqlConnection = new SQLConnection(); 

      stmt.sqlConnection.open(File.applicationStorageDirectory.resolvePath("assets/test.sqlite")); 
      stmt.text = "SELECT one, two FROM zero"; 
      stmt.execute(); 
      var result:Array = stmt.getResult().data; 
      resultArr = new ArrayCollection(); 
      if (result) 
      {  
       resultArr.source = result;   
      } 
     return resultArr; 
     } 
     [Bindable]private var resultArr:ArrayCollection = new ArrayCollection(); 

     protected function button1_clickHandler(event:MouseEvent):void 
     { 
      // TODO Auto-generated method stub 
      getData(); 
     } 

    ]]> 
</fx:Script> 
<s:Button label="OK" click="button1_clickHandler(event)"/> 
<s:List width="302" height="234" dataProvider="{resultArr}"></s:List> 
</s:View> 

由於誰想幫我。

Answer 1

您得到[object Object]，因爲正在返回的數據有多個值（第一列和第二列）。您需要告訴應用程序您想要顯示的內容。

嘗試設置將labelField參數，看看你會得到什麼：

<s:List width="302" height="234" dataProvider="{resultArr}" labelField="one"></s:List>
