bug 我这边 复现了，应该找到原因了， 马上解决

[iielse]

implementation 'com.github.iielse:imageviewer:2.1.8'

试下这个

已经用最新的版本了，我再观察下还会不会崩溃，具体原因是啥额，是执行退出动画的时候DialogFragment被销毁了么，但是什么情况下会导致执行退出动画时DialogFragment被销毁呢

[iielse]

上面是因为在 dialogFragment onDestroyView后了， 还在调用 fragment.dismissAllowingStateLoss() 崩溃的. 我自测是在 onRelease方法中直接调用 activity.finish() 触发了的.

解决方案是监听 fragment的声明周期，onDestroyView后加个标记.

fun end(fragment: DialogFragment, startView: View?, holder: RecyclerView.ViewHolder) {
        beforeTransition(startView, holder)
        val doTransition = {
            TransitionManager.beginDelayedTransition(holder.itemView as ViewGroup, transitionSet().also {
                it.addListener(object : TransitionListenerAdapter() {
                    override fun onTransitionStart(transition: Transition) {
                        animating = true
                    }

                    override fun onTransitionEnd(transition: Transition) {
                        if (!animating) return  // 这里
                        animating = false 
                        fragment.dismissAllowingStateLoss()
                    }
                })
            })
            transition(startView, holder)
        }
        holder.itemView.post(doTransition)

        fragment.lifecycle.addObserver(object : LifecycleObserver {
            @OnLifecycleEvent(Lifecycle.Event.ON_DESTROY)
            fun onDestroy() {
                fragment.lifecycle.removeObserver(this)
                animating = false // 这里
                holder.itemView.removeCallbacks(doTransition)
                TransitionManager.endTransitions(holder.itemView as ViewGroup)
            }
        })
    }
