Recyclerview Crashes When "scrapped Or Attached Views May Not Be Recycled"

I'm using a simple implementation of RecyclerView taken from the Android website using a StaggeredGridLayoutManager and I keep getting this error that crashes my app: java.lang.I

Solution 1:

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.

Solution 2:

I've had to deal with this crash also and in my case it had nothing to do with android:animateLayoutChanges.

The RecyclerView we were building had more than one type of views in it and some were having EditTexts in them. After a while we pinned the issue to being focus related. This bug happens while recycling EditTexts and one of them is focused.

Naturally we tried clearing the focus when new data is being bound to a recycled view but that didn't work until android:focusableInTouchMode="true" is set on RecycleView. Actually that is the only change that was needed in the end for this issue to go away.

Solution 3:

I removed the android:animateLayoutChanges from layout property and problem has been resolved.

Solution 4:

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.

Solution 5:

It took me two days but could not get around this, in the end, I had to disable the item prefetch.

When setting the layout manager you can simply call

mGridLayoutManager.setItemPrefetchEnabled(false);

It made the error go away for me. Hope it will be useful for someone.
