Xamarin AnimationEnd觸發事件只有一次

Question

所以我有這幾行代碼，我嘗試做一個動畫循環。不幸的是，只有在事件停止時才觸發一次。你能幫我麼？

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;
