Examples with TypeEvaluator android.animation.TypeEvaluator used on opensource projects

Example 1 with TypeEvaluator

use of android.animation.TypeEvaluator in project UltimateAndroid by cymcsg.

the class DynamicGridModification method animateBounds.

@TargetApi(Build.VERSION_CODES.HONEYCOMB)
private void animateBounds(final View mobileView) {
    TypeEvaluator<Rect> sBoundEvaluator = new TypeEvaluator<Rect>() {

        public Rect evaluate(float fraction, Rect startValue, Rect endValue) {

        }

        public int interpolate(int start, int end, float fraction) {
            return (int) (start + fraction * (end - start));
        }
    };
    ObjectAnimator hoverViewAnimator = ObjectAnimator.ofObject(mHoverCell, "bounds", sBoundEvaluator, mHoverCellCurrentBounds);
    hoverViewAnimator.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() {

        @Override
        public void onAnimationUpdate(ValueAnimator valueAnimator) {
            invalidate();
        }
    });
    hoverViewAnimator.addListener(new AnimatorListenerAdapter() {

        @Override
        public void onAnimationStart(Animator animation) {
            mHoverAnimation = true;
            updateEnableState();
        }

        @Override
        public void onAnimationEnd(Animator animation) {
            mHoverAnimation = false;
