Code demonstrating how you can keep your ExpansionTile widgets expanded when you set a new state and replace the data. The key is to generate the keys that ExpansionTile uses from attributes of your data that are unique. Code to focus on is line 105.

Fix for known bug when scrolling a RecyclerView inside SwipeRefreshLayout to the top and refresh is called prematurely, before the first item is shown.

	public class SwipeRefreshLayoutToggleScrollListener extends RecyclerView.OnScrollListener {
	private List<RecyclerView.OnScrollListener> mScrollListeners = new ArrayList<RecyclerView.OnScrollListener>();
	private int mExpectedVisiblePosition = 0;
	private SwipeRefreshLayout mSwipeLayout;

	public SwipeRefreshLayoutToggleScrollListener(SwipeRefreshLayout swipeLayout) {
	mSwipeLayout = swipeLayout;
	}
	public void addScrollListener(RecyclerView.OnScrollListener listener){
	mScrollListeners.add(listener);
