Question

我正在尝试向我的Android应用程序添加搜索/过滤功能。我将提供一个屏幕截图和一个编码副本，以便您可以看到我想要在这里得到的确切内容。我不确定最好的办法是什么。

        {
            // This method contains the selection assignments for the Calculator Views

            if(calcList.selectedIndex == 0)//A1c Calculator
            {

            {

根据您在图片中显示的内容，我不知道您为什么不能在当前布局中添加另一个“行”。从概念上讲是这样的：

<s:Label color="#1021C7" text="Welcome to iCalculate (4)" textAlign="center"
         verticalAlign="middle" click="navigator.pushView(views.CompanyDetail)"/>
    <s:HGroup>
     <s:TextInput id="searchInput"/> 
     <s:Button label="Search"/>
    </s:HGroup>
<s:List id="calcList" alternatingItemColors="[#e5e4e4,#ffffff]"
        width="100%"
        height="90%"
        labelField="name"
        change="calcList_changeHandler(event)">
....
