推荐答案

快速的答案 - 如果你需要在列表中的每个项目一个真正的视图那么你不希望使用虚拟化控制像一个ListView

Quick answer - if you need a real View for each item in your list then you don't want to use a virtualized control like a ListView.

相反，你可以使用滚动型内垂直的LinearLayout内重复自定义视图。

Instead you can use repeated custom views inside a vertical LinearLayout inside a ScrollView.

如果使用mvvmcross，你会发现一个MVXBindableLinearLayout有助于做到这一点 - 它有一个的ItemsSource和模板就像MvxBindableListView

If using mvvmcross, you may find a MVXBindableLinearLayout helpful to do this - it has an ItemsSource and a Template just like the MvxBindableListView.

我不知道是否你正在尝试做的是有意义的，但上面的应该，如果你想帮你做吧！

I've no idea whether what you are trying to do makes sense, but the above should help you do it if you want to!

不要试图采用线性布局，有很多项目列表 - 你会耗尽资源

Don't try using a linear layout for lists with lots of items - you'll run out of resources.
