如何在xamarin.android中创建自定义属性动画

// 自定义属性类
public class CustomProperty : Java.Lang.Object, IJavaObject
{
    private int value;

    public int Value
    {
        get { return value; }
        set { this.value = value; }
    }
}

// 自定义动画类
public class CustomAnimator : Java.Lang.Object, IAnimatorUpdateListener
{
    private CustomProperty property;

    public CustomAnimator(CustomProperty property)
    {
        this.property = property;
    }

    public void OnAnimationUpdate(ValueAnimator animation)
    {
        int animatedValue = (int)animation.AnimatedValue;
        property.Value = animatedValue;
    }
}

// 创建属性动画对象
CustomProperty customProperty = new CustomProperty();
ObjectAnimator animator = ObjectAnimator.OfInt(customProperty, "Value", 0, 100);
animator.SetDuration(1000);
animator.SetInterpolator(new AccelerateDecelerateInterpolator());

// 启动属性动画
animator.Start();
