https://developer.aliyun.com/profile/5yerqm5bn5yqg?spm=a2c6h.12873639.0.0.6eae304abcjaIB出现同样的错误,
而且不是每次都出现这个问题,
privatestaticboolean shouldHandleMeasuredHeightTooSmall(Viewview ,PercentLayoutInfoinfo){ intstate=ViewCompat. getMeasuredHeightAndState(view)&ViewCompat. MEASURED_STATE_MASK ; returnstate==ViewCompat. MEASURED_STATE_TOO_SMALL&&info. heightPercent. percent>= 0&&info. mPreservedParams. height==ViewGroup.LayoutParams. WRAP_CONTENT ;}估计是info为null才报错的,
能判断下就应该能解决这个问题
