Xamarin表单按钮没有边框问题

问题描述

我尝试在视图中呈现可单击项的列表.我想添加一个带有图像和白色边框的按钮(第一个).我发现StackLayout/ViewCell中的按钮无法呈现边框.

I try to render a list of clickable items in a view. I would like to add a button with an image and a white border (the first one). I discovered that the buttons in my StackLayout/ViewCell can't render a border.
