RecyclerView crashes when “scrapped or attached views may not be recycled”

Question

I\'m using a simple implementation of RecyclerView taken from the Android website using a StaggeredGridLayoutManager and I keep getting this error

Answer 1

Among the reasons that anyone can face this issue, check if you have set the attribute android:animateLayoutChanges="true"to the RecyclerView. This will cause the recycling and reattaching the RecyclerView's items to fail. Remove it and assign the attribute to the RecyclerView's parent container, such as a LinearLayout/RelativeLayout and you should see the problem go away.

Answer 2

I too was getting this error whenever i had animateLayoutChanges="true" in layout file for RecyclerView. Delete this attribute and error will disappear!

Answer 3

Workaround solution if reason of Exception is what itemView has parent. In code, where you have notifyItemRemoved(position), remove itemView from RecyclerView:

View itemView = mRecyclerView.getLayoutManager().findViewByPosition(position);
if (itemView != null && itemView.getParent() != null) {
    ((ViewGroup) itemView.getParent()).removeView(itemView);
}
notifyItemRemoved(position);

Answer 4

This error is caused if in your XML you have android:animateLayoutChanges set to true and you call notifyDataSetChanged() on the RecyclerView's adapter in the Java code.

So, just avoid using android:animateLayoutChanges with RecyclerViews.

Answer 5

In my case it happened because I had a Transition running when trying to resize the RecyclerView because the software keyboard was about to show.

I fixed it my excluding the RecyclerView from the Transition by using Transition.excludeTarget(R.id.recyclerview, true);

Answer 6

Let me add another possible fix for this kind of issue, please. I had the same problem with superSlim library for sticky headers in RecyclerView. I used MatrixCursor to set data to RecyclerViewCursorAdapter. The reason for this issue was ID columns equals to 0 for all headers. Hope that would help someone to save couple days of debugging.
