Xamarin AnimationEnd 事件只触发一次

Question

所以我用这几行代码尝试制作动画循环。不幸的是，它只会在事件停止时触发一次。你能帮帮我吗？

ImageView imgView1 = FindViewById<ImageView>(Resource.Id.falling_stars1);
ImageView imgView2 = FindViewById<ImageView>(Resource.Id.falling_stars2);

Android.Animation.ObjectAnimator animator1 = Android.Animation.ObjectAnimator.OfFloat(imgView1, "y", -700, 100);
Android.Animation.ObjectAnimator animator2 = Android.Animation.ObjectAnimator.OfFloat(imgView2, "y", 100, 900);

animator1.SetDuration(2000);
animator2.SetDuration(2000);
animator1.Start();
animator2.Start();

animator1.AnimationEnd += delegate
{
    animator1.Start();
};

animator2.AnimationEnd += delegate
{
    animator2.Start();
};

Answer 1

RepeatMode: Defines the animation behavior when it reaches the end and the repeat count is greater than 0 or infinite.

Android.Animation.ObjectAnimator animator1 = Android.Animation.ObjectAnimator.OfFloat(imgView1, "y", -700, 100);
animator1.SetDuration(2000);
animator1.RepeatCount = ValueAnimator.Infinite;
animator1.RepeatMode = ValueAnimatorRepeatMode.Restart;
