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：

@Overridepublic View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState){// Inflate the layout for this fragmentfinal 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)@Overridepublic 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() {@Overridepublic void onAnimationEnd(Animator animation) {infoContainer.setVisibility(View.INVISIBLE);}});reveal.start();}}
