Answer 1

对于按钮Android上的删除阴影,您只需在项目Droid中创建渲染器并使用透明或其他颜色设置BackroundColor.

对于使用PCL的项目:

[assembly: ExportRenderer(typeof(Button),typeof(FlatButtonRenderer))]
namespace Project.Droid
    {
        public class FlatButtonRenderer : ButtonRenderer
        {
            protected override void OnDraw(Android.Graphics.Canvas canvas)
            {
                base.OnDraw(canvas);
            }
        }
    }

在XAML中:

<Button BackgroundColor="Transparent" Text="ClickMe"/>

更详细地解释.

using Android.App;
using Android.Content.PM;
using Android.OS;
using Xamarin.Forms.Platform.Android;
using ProjectName.Droid;
using Xamarin.Forms;

[assembly: ExportRenderer(typeof(Xamarin.Forms.Button), typeof(FlatButtonRenderer))]
namespace ProjectName.Droid
{    
    public class FlatButtonRenderer : ButtonRenderer
    {
        protected override void OnDraw(Android.Graphics.Canvas canvas)
        {
            base.OnDraw(canvas);
        }
    }
}
