[android-developers] Re: Dynamically change fromDegrees and toDegrees params in RotateAnimation

I'm thinking maybe you should subclass Animation and override these two methods:

boolean	getTransformation(long currentTime, Transformation outTransformation, float scale) Gets the transformation to apply at a specified point in time.
boolean	getTransformation(long currentTime, Transformation outTransformation) Gets the transformation to apply at a specified point in time.

I've defined RotateAnimation to rotate a ImageView. So, I want to stop the animation after some repeats. The scenario is as following :

First animation starts from -25 to 25 degree, after one animating, this should be change to -24 to 24 and reversely and ... and when reach to 0 to 0 this should be cancel.

    int intervalSize = -25;

    RotateAnimation r = new RotateAnimation(intervalSize, intervalSize, pivotX, pivotY);
    r.setDuration(3000);
    r.setStartOffset(0);
    r.setRepeatMode(RotateAnimation.REVERSE);
    r.setRepeatCount(RotateAnimation.INFINITE);
    startAnimation(r);
    r.setAnimationListener(new AnimationListener() {

        @Override
        public void onAnimationStart(Animation animation) {

        }

        @Override
        public void onAnimationRepeat(Animation animation) {
            if (intervalSize == 0)
                animation.cancel();
            intervalSize--;
        }

        @Override
        public void onAnimationEnd(Animation animation) {

        }
    });

Could any one please how can I reach to this ?

Thanks in advance‌:)
