How to stop an animation cancel does not work

Question

I need to stop a running translate animation  The  cancel   method of Animation has no effect  the animation goes until the end anyway   How do you cancel a running animation

To stop animation you may set such objectAnimator that do nothing, e.g.

first when manual flipping there is animation left to right:

flipper.setInAnimation(leftIn);
flipper.setOutAnimation(rightOut);

then when switching to auto flipping there's no animation

flipper.setInAnimation(doNothing);
flipper.setOutAnimation(doNothing);

doNothing = ObjectAnimator.ofFloat(flipper, "x", 0f, 0f).setDuration(flipperSwipingDuration);

On Android 4 4 4  it seems the only way I could stop an alpha fading animation on a View was calling View animate   cancel    i e   calling  cancel   on the View s ViewPropertyAnimator    Here s the code I m using for compatibility before and after ICS   public void stopAnimation View v        v clearAnimation        if  canCancelAnimation              v animate   cancel                  with the method          Returns true if the API level supports canceling existing animations via the    ViewPropertyAnimator  and false if it does not     return true if the API level supports canceling existing animations via the    ViewPropertyAnimator  and false if it does not     public static boolean canCancelAnimation         return Build VERSION SDK INT  gt   Build VERSION CODES ICE CREAM SANDWICH      Here s the animation that I m stopping   v setAlpha 0f   v setVisibility View VISIBLE      Animate the content view to 100  opacity  and clear any animation listener set on the view  v animate        alpha 1f       setDuration animationDuration       setListener null

What you can try to do is get the transformation Matrix from the animation before you stop it and inspect the Matrix contents to get the position values you are looking for   Here are the api s you should look into   public boolean getTransformation  long currentTime  Transformation outTransformation   public Matrix getMatrix     public void getValues  float   values   So for example  some pseudo code  I have not tested this    Transformation outTransformation   new Transformation    myAnimation getTransformation currentTime  outTransformation   Matrix transformationMatrix   outTransformation getMatrix    float   matrixValues   new float 9   transformationMatrix getValues matrixValues   float transX   matrixValues Matrix MTRANS X   float transY   matrixValues Matrix MTRANS Y

Use the method setAnimation null  to stop an animation  it exposed as public method in View java  it is the base class for all widgets  which are used to create interactive UI components  buttons  text fields  etc               Sets the next animation to play for this view         If you want the animation to play immediately  use          link  startAnimation android view animation Animation   instead         This method provides allows fine-grained        control over the start time and invalidation  but you        must make sure that 1  the animation has a start time set  and        2  the view s parent  which controls animations on its children         will be invalidated when the animation is supposed to        start                 param animation The next animation  or null              public void setAnimation Animation animation
