如何在xamarin形式的列表视图中显示从1到如此的行号?
我有一个要求，我必须创建一个listView来为每个商品添加商品编号.我有一个在项目模型中放入数字的想法，但我无法弄清楚.
I have got a requirement where I have to create a listView which adds item number with each item. I have got an idea of putting a number in model of item but I am unable to figure that out.
最简单的方法应该是向绑定到ListView.ItemsSource的ViewModel添加一个附加属性Index屏幕.
The easiest way should be to add one additional property Index to the ViewModel that is bound to the the ListView.ItemsSource and then simply represent it on the screen.
或者，如果需要多次使用枚举的ListView，则可以创建可重复使用的控件，并将逻辑从ViewModel移到UI层.
Alternatively, if there is a need to use an enumerated ListView multiple times you could create a reusable control and move the logic from the ViewModel to the UI layer.
所以这一切都取决于您的需求.
So it all depends on your needs.
