我無法播放動畫故事板。僅顯示最後一張圖片動畫。 什麼可能是錯的?不在故事板中播放動畫(使用ObjectAnimationUsingKeyFrames)
我的代碼創建動畫:
public static class AnimationHelper
{
private const string PathImageAnimation = "/LeSommet.ZooSnap.UI.WindowsPhone;component/Resources/Images/Animation/ButtonState{0}.png";
public static void StartAnimation(UIElement target)
{
Storyboard storyboard = new Storyboard();
ObjectAnimationUsingKeyFrames objectAnimation = new ObjectAnimationUsingKeyFrames();
objectAnimation.AutoReverse = false;
objectAnimation.SpeedRatio = 2;
Storyboard.SetTargetProperty(objectAnimation, new PropertyPath("Source"));
Storyboard.SetTarget(objectAnimation, target);
for (int i = 1; i <= 4; i++)
{
DiscreteObjectKeyFrame discreteObject = new DiscreteObjectKeyFrame()
{
KeyTime = TimeSpan.FromMilliseconds(1000),
Value = new BitmapImage(new Uri(string.Format(PathImageAnimation, i), UriKind.Relative))
};
objectAnimation.KeyFrames.Add(discreteObject);
}
storyboard.Children.Add(objectAnimation);
storyboard.Begin();
}
}
我的代碼圖片XAML:
<Image Source="/LeSommet.ZooSnap.UI.WindowsPhone;component/Resources/Images/Animation/ButtonState5.png"
VerticalAlignment="Center"
HorizontalAlignment="Center"
Width="110" Height="110" Stretch="Fill"
