无法在独立视图上启动此动画制作器！揭示效果

这就是我解决的方法，我在onCreateView回调中向视图添加了onLayoutChange侦听器，因此无论何时将其附加到视图并准备进行绘制，它都可以显示

@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);         toggleInformationView(view);     } });        }        return view;    }
