如何更改 ListView 中项目的高度？

Question

我的列表视图的视觉显示有问题。我的项目的高度太小。首先我认为我的列表是空的。但是当我单击项目时，操作有效并且所选项目的信息被传输.然后我只写了3个标签，列表只显示2个标签，然后我明白我的项目高度太小/我试图改变我的列表高度，ViewCell.View,Labels，但它不起作用。请帮忙我

ListView 内部有一个Row height 属性：

C#：

RowHeightDemoListView.RowHeight = 100;

Xaml：

<ListView x:Name="RowHeightDemoListView" RowHeight="100" />
