如何以编程方式将Xamrin应用程序带到前台？

using Android.App;
using Android.Content;

public void BringAppToFront()
{
    var currentActivity = MainActivity.Current;
    if (currentActivity != null)
    {
        currentActivity.MoveTaskToFront(ActivityFlags.NewTask);
    }
}

using UIKit;

public void BringAppToFront()
{
    UIApplication.SharedApplication.OpenUrl(new NSUrl("app://"));
}

public interface IAppForegroundService
{
    void BringAppToFront();
}

using Android.App;
using Android.Content;
using YourApp.Droid; // 替换为你的命名空间
using Xamarin.Forms;

[assembly: Dependency(typeof(AppForegroundService))]
namespace YourApp.Droid
{
    public class AppForegroundService : IAppForegroundService
    {
        public void BringAppToFront()
        {
            var currentActivity = MainActivity.Current;
            if (currentActivity != null)
            {
                currentActivity.MoveTaskToFront(ActivityFlags.NewTask);
            }
        }
    }
}

using UIKit;
using YourApp.iOS; // 替换为你的命名空间
using Xamarin.Forms;

[assembly: Dependency(typeof(AppForegroundService))]
namespace YourApp.iOS
{
    public class AppForegroundService : IAppForegroundService
    {
        public void BringAppToFront()
        {
            UIApplication.SharedApplication.OpenUrl(new NSUrl("app://"));
        }
    }
}

var appForegroundService = DependencyService.Get<IAppForegroundService>();
appForegroundService.BringAppToFront();
