    Expert tip

    This happens when you have android:animateLayoutChanges set to true in your XML file and you call notifyDataSetChanged(). To fix it, you have to set android:animateLayoutChanges to false.

  2. ,

    In your xml just avoid using android:animateLayoutChanges with RecyclerViews.and also if you have set android:focusableInTouchMode="true" in your RecycleView you have to set false.
