我用这方法可以解决问题了，但是不知道出问题在哪里； 方法一 自己写一个继承LinearLayoutManager的包装类，在onLayoutChildren()方法里try-catch捕获该异常。

@Override public void onLayoutChildren(RecyclerView.Recycler recycler, RecyclerView.State state) { try { super.onLayoutChildren(recycler, state); } catch (IndexOutOfBoundsException e) { e.printStackTrace(); } }

我也是只有一个的话，adapter.notifyItemRemoved(pos);会闪退报错
