我通过listview旋转270度和contentview在datatemplate旋转90度来动态创建水平listview,但contentview没有展开

我试过设置VerticalOptions=“FillAndExpand”和HorizontalOptions=“FillAndExpand”,也试过设置RelativeLayout.WidthConstraint和RelativeLayout.HeightConstraint,但都不起作用


预期布局



为了实现类似水平listview的输出,您可以使用上述代码中所示的可绑定布局

您可以提供一个关于所需效果的屏幕截图吗?@LucasZhang MSFT我已经添加了,thanks@SutineeM. 我建议在datatemplate中使用Grid而不是“ContentView中的StackLayout”,因为Grid布局可以很好地扩展。我认为添加contentview和stacklayout太复杂了。另外,不要对标签使用硬编码的高度和宽度,而应使用换行符限制它们。希望有帮助。@Dilmah我尝试使用网格,但它不起作用为什么scrollview不滚动?scrollview不滚动,因为我在relativelayout中设置了srollview,所以我刚刚删除了relativelayout,现在可以了。非常感谢。
