在使用fragment添加添加新特新动画的时候，报这个错了，解决方法如下：

@Override    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)    {        // Inflate the layout for this fragment        final View view = inflater.inflate(R.layout.fragment_map_list, container, false);        if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {            view.addOnLayoutChangeListener(new View.OnLayoutChangeListener() {                @TargetApi(Build.VERSION_CODES.LOLLIPOP)                @Override                public void onLayoutChange(View v, int left, int top, int right, int bottom, int oldLeft, int oldTop, int oldRight, int oldBottom) {                    v.removeOnLayoutChangeListener(this);                    //进行自己的动画操作                    toggleInformationView(view);                }            });        }        return view;    }

private void toggleInformationView(View view) {        infoContainer = view.findViewById(R.id.contact_card);        int cx = (view.getLeft() + view.getRight()) / 2;        int cy = (view.getTop() + view.getBottom()) / 2;        float radius = Math.max(infoContainer.getWidth(), infoContainer.getHeight()) * 2.0f;        if (infoContainer.getVisibility() == View.INVISIBLE) {            infoContainer.setVisibility(View.VISIBLE);            ViewAnimationUtils.createCircularReveal(infoContainer, cx, cy, 0, radius).start();        } else {            Animator reveal = ViewAnimationUtils.createCircularReveal(                    infoContainer, cx, cy, radius, 0);            reveal.addListener(new AnimatorListenerAdapter() {                @Override                public void onAnimationEnd(Animator animation) {                    infoContainer.setVisibility(View.INVISIBLE);                }            });            reveal.start();        }    }
