Xamarin表单按钮没有边框问题 [英] Xamarin forms button with no border issue

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.

推荐答案

您是否正在使用Android?如果是，则:

Are you using Android? If yes, then:

在Android上，除非 VisualElement.BackgroundColor设置为非默认颜色.

On Android this property will not have an effect unless VisualElement.BackgroundColor is set to a non-default color.
