Xamarin-XAML网格UI相互覆盖,xaml,xamarin,xamarin.ios,xamarin.forms,xamarin-studio,Xaml,Xamarin,Xamarin.ios,Xamarin.forms,Xamarin Studio,我正在使用我放在StackLayout中的Xamarin中的网格创建UI。下面是xaml的以下代码 program.xaml <?xml version="1.0" encoding="UTF-8"?> <ContentPage xmlns="http://xamarin.com/schemas/2014/forms" xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml" x:Class="LoginPage.Page"
