Flex 4.6移动sqlite特定数据

首先，我是使用Flex的新手，但我已经将这个应用程序与在线教程和信息的帮助结合在一起。基本上我的应用程序就像名称，地址等等的目录，但我还有“周”和“日”的其他字段。我想要做的是列出只显示星期一至星期一的名称。以下是我用来帮助您理解我所要做的一些代码。我感谢任何帮助！Flex 4.6移动sqlite特定数据

<s:List dataProvider="{AddDoctorDatabase.doctors()}" labelField="name" change="onDoctorSelected(event)" 
     left="0" right="0" top="0" bottom="0"> 
</s:List> 


public static function doctors():ArrayCollection 
    { 
     var doctorList:ArrayCollection = new ArrayCollection(); 

     var sql:String = "SELECT id, week, day, name, address, city, state, zip, phone FROM doctors"; 
     var stmt:SQLStatement = new SQLStatement(); 
     stmt.sqlConnection = sqlConnection; 
     stmt.text = sql; 
     stmt.execute(); 
     var sqlResult:SQLResult = stmt.getResult(); 
     if (sqlResult) { 
      var result:Array = sqlResult.data; 
      if (result) { 
       for (var index:Number = 0; index < result.length; index++) { 
        doctorList.addItem(processRow(result[index])); 
       } 
      } 
     } 
     return doctorList; 
    }

我不知道，我明白你的问题，如果我做你需要的是在S中的labelFunction：列表，而不是使用的labelField，这样你就可以合相，你要为显示领域的功能应该带一个item：Object参数，它将被输入为你的数据提供者的数据元素之一，它应该返回a：String类似... function myLabelFunction（item：Object）：String，在函数中你会做类似return item.weekValue +“ - ”+ item.dayValue – shaunhusain 2012-03-02 19:27:31

基本上sqlite数据库有id，week，name，地址，城市，州，邮编，电话。我希望能够填充显示特定星期和特定日期的名称的列表。例如，显示星期二的第1周的所有名称。 – Nik 2012-03-03 17:38:51

好吧2个问题，我想我可以给你一个答案。 1什么是processRow？ 2你是否有其他的输入框，你可以选择星期和星期几，并且你希望它给你只有那一周和那天的行数？ – shaunhusain 2012-03-05 05:49:48

这应该工作，我想
我不是专家，但我认为比这能帮助你！

我认为这会工作，但我得到一个错误1137：不正确的参数数量，预计不会超过1为以下行doctorList.addItem（result [index] .week，result [index] .day，result [index ]。名称）; – Nik 2012-03-03 02:04:33

当我切换到列表视图的设计模式时，我也遇到了一个错误，我从未见过这个，但我看不到任何设计。它只是说“如果该属性也被明确设置为标记或属性，则无法为默认属性数据提供者指定值”。 – Nik 2012-03-03 02:28:41

您必须在代码的其他部分初始化dList变量，请尝试在另一个函数中执行此'dList = doctors（）'，而不是在dataProvider（dataProvider =“{dList}”） – Superlandero 2012-03-05 19:01:38

假设这是由Christophe Coenraets的employee directory sample启发，你必须创建一个医生级别，并设置在processRow功能的公共变量，在ArrayCollection中加入新创建的医生对象之前，您检索到的数据：

} 

private function creationComplete_handler(event:Event):void 
{ 
    dList = getAllDoctors(); 
} 

public function getAllDoctors():ArrayCollection 
{ 
    var doctorList:ArrayCollection = new ArrayCollection(); 

    var sql:String = "SELECT id, week, day, name, address, city, state, zip, phone FROM doctors"; 
    var stmt:SQLStatement = new SQLStatement(); 
    stmt.sqlConnection = sqlConnection; 
    stmt.text = sql; 
    stmt.execute(); 
    var result:Array = stmt.getResult().data; 
    if (result) 
    { 
     for (var index:Number = 0; index < result.length; index++) 
     { 
     //doctorList.addItem(processRow(result[index])); 
     doctorList.addItem({result[index].week, result[index].day, result[index].name}); 
     } 
     return doctorList; 
    } 
    else 
    { 
    return null; 
    } 
} 
public function processRow(o:Object):Doctor 
{ 
    var d:Doctor = new Doctor(); 
    d.Name = o.name; 
    d.week = o.week; 
    d.day = o.day; 

    return d; 
} 
public class Doctor() 
{ 
    public function Doctor(){} 
    public var name:String; 
    public var week:String; 
    public var day:int; 
} 

//Call this one when they select a week and day and hit a button, or just

public function getDoctorForWeekAndDay(chosenWeek:String, chosenDay:String):ArrayCollection
