question: View findHiddenNonRemovedView ( int position , int type ) { final int count = mHiddenViews . size ( ) ; for ( int i = 0 ; i < count ; i ++ ) { final View view = mHiddenViews . get ( i ) ; RecyclerView . ViewHolder holder = mCallback . getChildViewHolder ( view ) ; if ( holder . getPosition ( ) == position && ! holder . isInvalid ( ) && ( type == RecyclerView . INVALID_TYPE || holder . getItemViewType ( ) == type ) ) { return view ; } } return null ; }
target:  This can be used to find a disappearing view by position.
