我们在 Xamarin Forms 中使用新的实验性单选按钮: https://learn.microsoft.com/en-us/xamarin/xamarin-forms/user-interface/radiobutton
Xamarin.Forms 版本 - 4.8.0.1269
单选按钮在 Android 9 及更低版本的设备中完美运行。但在 Android 10/11 上,如果手机主题设置为浅色主题,则单选按钮图标会丢失。以下分别是深色和浅色主题的示例屏幕截图:
这是为单选按钮编写的代码:
<StackLayout VerticalOptions="Start"
HorizontalOptions="FillAndExpand">
<Label Text="Body temperature"
Style="{StaticResource BlackBoldLabelStyle}"
VerticalOptions="Start"
HorizontalOptions="StartAndExpand" />
<StackLayout VerticalOptions="Start"
Margin="0,10,0,0"
HorizontalOptions="FillAndExpand"
Orientation="Horizontal">
<StackLayout.GestureRecognizers>
<TapGestureRecognizer Command="{Binding OnBodyTempOption1Click}"/>
</StackLayout.GestureRecognizers>
<RadioButton
HorizontalOptions="Start"
VerticalOptions="Center"
IsChecked="{Binding IsBodyTempOption1Check}"/>
<Label Text="Less than 99.5 degree F / 37.5 degree C"
VerticalOptions="Center"
Style="{StaticResource DarkGrayLabelStyle}"
HorizontalOptions="StartAndExpand" />
</StackLayout>
<StackLayout VerticalOptions="Start"
Margin="0,5,0,0"
HorizontalOptions="FillAndExpand"
Orientation="Horizontal">
<StackLayout.GestureRecognizers>
<TapGestureRecognizer Command="{Binding OnBodyTempOption2Click}"/>
</StackLayout.GestureRecognizers>
<RadioButton
HorizontalOptions="Start"
VerticalOptions="Center"
IsChecked="{Binding IsBodyTempOption2Check}"/>
<Label Text="More than 99 degree F / 37 degree C"
VerticalOptions="Center"
Style="{StaticResource DarkGrayLabelStyle}"
HorizontalOptions="StartAndExpand" />
</StackLayout>
</StackLayout>
