actionscript-3 - 仅增加一个 ItemRender 的高度

Question

我正在尝试使用 Flex 开发调用日志，但在 ItemRender 方面遇到一些问题。事实上，这就是我所得到的:

当您单击某个项目时，该项目的大小会发生变化以显示更多详细信息:

但正如您所看到的，每个项目都会受到此调整大小的影响。平铺布局采用最高渲染并将其高度应用于其他渲染。

这是我的代码，我在其中调用渲染:

    <s:DataGroup id="TileListUsers"
                 left="10" right="10" top="10" bottom="10" width="300"
                 itemRenderer="assets.render.CallLogRender"
                 dataProvider="{ListCall}"
                 horizontalCenter="0" verticalCenter="0" contentBackgroundAlpha="0.0">
        <s:layout>
            <s:TileLayout horizontalGap="15" requestedColumnCount="1" verticalGap="15" />
        </s:layout>
    </s:DataGroup>

在渲染中，我使用了三个 BorderContainer，一个用于第一个 block ，一个用于第二个 block ，一个用于它们之间显示的详细信息:

        override public function set data(value:Object):void {
            super.data = value;

            CallerIDLabel.text = "Appel du : " + data.CallerID;
            StartHourLabel.text = data.StartHour;
            StartDateLabel.text = data.StartDate;
            if(value == null){
                return;
            }
            if (!data.Answer){      
                ShadowColor.color=0xCC9900;
                CallerIDLabel.text = "Appel manqué : " + data.CallerID;
                SourceIcon.source=callFinished;
            }   
        }

        private function onClick():void{
            if (data.Answer){
                this.height=170;
                DetailLineContainer.visible=true;
                SecondBlocContainer.visible=true;
            }
        }
    ]]>

有没有一种方法可以让 TileLayout 只增加一个组件的高度而不影响其他组件？

Answer 1

如果只有一列，为什么要使用TileLayout？使用 VerticalLayout 并将其 variableRowHeight 属性设置为 true。这是 example .
