Example 6 with RectEvaluator

use of android.animation.RectEvaluator in project android_frameworks_base by DirtyUnicorns.

the class ChangeClipBounds method createAnimator.

@Override
public Animator createAnimator(final ViewGroup sceneRoot, TransitionValues startValues, TransitionValues endValues) {
    if (startValues == null || endValues == null || !startValues.values.containsKey(PROPNAME_CLIP) || !endValues.values.containsKey(PROPNAME_CLIP)) {
        return null;
    }
    Rect start = (Rect) startValues.values.get(PROPNAME_CLIP);
    Rect end = (Rect) endValues.values.get(PROPNAME_CLIP);
    if (start == null && end == null) {
        // No animation required since there is no clip.
        return null;
    }
    if (start == null) {
        start = (Rect) startValues.values.get(PROPNAME_BOUNDS);
    } else if (end == null) {
        end = (Rect) endValues.values.get(PROPNAME_BOUNDS);
    }
    if (start.equals(end)) {
        return null;
    }
    endValues.view.setClipBounds(start);
    RectEvaluator evaluator = new RectEvaluator(new Rect());
    return ObjectAnimator.ofObject(endValues.view, "clipBounds", evaluator, start, end);
