xamarin--softinputresize,输入框获取焦点后，自动调整页面高度

重点代码：

using Xamarin.Forms;
using Xamarin.Forms.PlatformConfiguration;
using Xamarin.Forms.PlatformConfiguration.AndroidSpecific;
using Xamarin.Forms.Xaml;

namespace JKSY.Views
{
    [XamlCompilation(XamlCompilationOptions.Compile)]
    public partial class LoginView : ContentPage
    {
        public LoginView()
        {
            InitializeComponent();
        }
        protected override void OnAppearing()
        {
            base.OnAppearing();
            Xamarin.Forms.Application.Current.On<Xamarin.Forms.PlatformConfiguration.Android>().UseWindowSoftInputModeAdjust(WindowSoftInputModeAdjust.Resize);
        }

        protected override void OnDisappearing()
        {
            base.OnDisappearing();
            Xamarin.Forms.Application.Current.On<Xamarin.Forms.PlatformConfiguration.Android>().UseWindowSoftInputModeAdjust(WindowSoftInputModeAdjust.Pan);
        }
    }
}
