App crashes with empty list about expandable-recycler-view HOT 7 CLOSED

Hello, I encounter the same problem, it is exactly same as yours.
Is this issue solved now? Can you show your solution here? Really thanks.

from expandable-recycler-view.

Along with notifyGroupDataChanged() mentioned in adapter here,
#27 (comment)

Create copies of ExpandableList & ExpandableRecyclerViewAdapter in your project.
Modify ExpandableList function :

private int numberOfVisibleItemsInGroup2(int group) {
if (expandedGroupIndexes != null && expandedGroupIndexes.length > 0
&& expandedGroupIndexes.length > group) {
if (expandedGroupIndexes[group]) {
return groups.get(group).getItemCount() + 1;
} else {
return 1;
}
}
return 0;
}

Use the modified list in your copied ExpandableRecyclerViewAdapter.
Use the pair of these 2 modified classes.

As i understood, the solution provided above is incorrect. Dont use it. Follow the solution, provided by link below instead, without any modifying of library source code:

#27 (comment)

#61 (comment)
The mentioned solution is worked for me, even the edited version of comment is a working solution. Done some edits to make it more clear.

I was using only #27 (comment) which still leads to some crashes when you do updates group & children data.
So the change mentioned in #61 (comment) is required.
