我正在使用Xamarin.Forms并且正在瞄准iOS和Android.

默认视图

键盘打开,背景图像被挤压

背景图像也在景观模式中被挤压

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="XilnexOTM.Views.LoginPage"
             BackgroundImage="bg1.png" >
    <ScrollView>
        <StackLayout Orientation="Vertical">
            <Label Text="PICTURE"  />
            <Label Text="PIC 2" />

            <Entry Placeholder="Username" />
            <Entry Placeholder="Password" IsPassword="true"/>

            <Button x:Name="btn_Login"
                    Text="Login"
                    BackgroundColor="#FF0000"/>

        </StackLayout>
    </ScrollView>
</ContentPage>

是否有任何可能的方法将概念CSS应用于Xamarin.Forms？

xx {
 background-size: cover;
 background-position: right bottom;
}

在我的Playstore中,我注意到反混淆代码包含了大量<OR>的堆栈跟踪.

(例子at <OR>.onAttach(ProfileLandingFragment.java)).

这<OR>意味着什么？
