布局中使用app:overlay="false" 与autoRefresh(); 同时使用会出现NullPointException

报错代码 ``` public void autoRefresh() { updateListener(); if(isOverlay) { mHeadLayout.getLayoutParams().height = (int) mHeadHeight; mHeadLayout.requestLayout(); }else { createAnimatorTranslationY(mChildView, mHeadHeight, mHeadLayout); } } ``` 在程序执行到mHeadLayout.getLayoutParams().height = (int) mHeadHeight; 时出现空指针 布局文件如下 ``` ```
