我来修正代码块，将ListView的Clear方法替换为正确的Elements属性设置。

[ai-commands 块1，已执行]

[ai-commands 块1，已执行] 是个什么鬼
抱歉，这是我的回复格式问题。我来重新生成正确的代码块部分。

[ai-commands 块1，已执行]

还是一样

AI伴侣出现错误: The operation TextAlignment cannot accept the arguments: , ["Right"]
AI伴侣出现错误: The operation AlignHorizontal cannot accept the arguments: , ["Center"]

我检查了组件元数据，发现Label组件没有TextAlignment属性。我需要移除这个属性设置，只设置其他属性。
AI助手生成的代码,设置不存在的属性,一定要禁止这种,否则可能破坏项目
我检查了组件元数据，发现Label组件没有TextAlignment属性属性设置前要探测好
