我有一个带有自定义 ItemRenderer (IR) 的 TileList。IR 可以是 TextInput、TextArea 或 ComboBox。如果连续有一个 TextArea,我希望这一行的高度比其他行高。毕竟,我不在乎所有行是否必须具有相同的高度。我关心的是,如果我有一个没有 TextArea 的表单,我希望行高尽可能低。
经过一番工作,我实现了以下代码。但是,正如您在随附的屏幕截图中所欣赏的那样,我还没有实现我想要的。第一次输入表格时,它看起来不对,但第二次输入时,它看起来没问题。但是,如果您输入另一个具有不同字段的表单,然后重新打开之前打开的那个,它看起来又是错误的。当它看起来不对时,似乎每一行都有标准高度。
我错过了什么?我应该以某种方式自定义 TileList 吗?我是否将 invalidateDisplayList 和 invalidateSize 放在了错误的位置?

谢谢你的帮助!
