如何旋转 xamarin 表单中的按钮？

Question

我试图在 xamarin 中旋转一个按钮，但它什么也没做，我还尝试删除角半径，所以它不会是圆的，但它也什么也没做。我想把它旋转180度来翻转它。

Answer 1

这是你需要的吗

如果是，Rotation="180" 就是答案

Xaml

<StackLayout BackgroundColor="LightPink" Padding="20" Margin="0" Spacing="0" HorizontalOptions="FillAndExpand" VerticalOptions="FillAndExpand">
     <Button BackgroundColor="LightGreen" Padding="0" Margin="0" WidthRequest="100" HeightRequest="100" CornerRadius="50"
             Text="Up" HorizontalOptions="CenterAndExpand" VerticalOptions="StartAndExpand"/>
     <Button BackgroundColor="LightBlue" Padding="0" Margin="0" WidthRequest="100" HeightRequest="100" CornerRadius="50"
             Text="Down" HorizontalOptions="CenterAndExpand" VerticalOptions="EndAndExpand" Rotation="180"/>
</StackLayout>

这是我的代码，请运行你的项目看看效果。

<StackLayout HorizontalOptions="Center" VerticalOptions="Start">
            <Button
                x:Name="button1"
                Margin="35"
                BorderColor="Gray"
                BorderWidth="10"
                CornerRadius="80"
                HeightRequest="160"
                HorizontalOptions="Center"
                Rotation="180"
                Text="CLICK ME"
                VerticalOptions="Center"
                WidthRequest="160" />
        </StackLayout>
        <StackLayout HorizontalOptions="Center" VerticalOptions="EndAndExpand">
            <Button
                x:Name="button2"
                Margin="35"
                BorderColor="Gray"
                BorderWidth="10"
                CornerRadius="80"
                HeightRequest="160"
                HorizontalOptions="Center"
                Text="CLICK ME"
                VerticalOptions="Center"
                WidthRequest="160" />
        </StackLayout>
