由于我不喜欢Xamarin的Android目标的黑暗主题,我在Manifest.xml
中使用它切换到全息照明:
当按钮和标签显示正确的颜色时,如此创建的菜单不会:
var navMenu = new TableView {
Intent = TableIntent.Menu,
Root = new TableRoot {
菜单TableView在浅灰色背景上显示白色文本。很难读。
我可以指示Xamarin.Forms一致地切换颜色吗?

要在Xamarin Forms中实现Android特定平台样式,我在我的项目中执行了以下操作:
<强> Style.xml:强>
<resources>
<style name="Theme.Splash"
parent="android:Theme">

活动代码:
namespace Test.Droid
{
[Activity(Label = "Test", ConfigurationChanges = ConfigChanges.Orientation | ConfigChanges.ScreenSize,Theme = "@style/Theme.Main")]
public class MainActivity : AndroidActivity
{
}
