@itegulov got any other solution for ExpandableRecyclerView ? it's a library project without sample !!

[robUx4]

Did you call setStableIdsMode() first ?

[fadelakin]

@robUx4 how would one go about implementing this in their project?

[johnjohndoe]

👍 for a sample project and some basic documenation, please.

[LouisLin0706]

Good idea , can give some sample code to how to use this library~>?

[srikanth569]

Always write a sample project if you want people to use your library.

[LOG-TAG]

@srikanth569 I'm using this https://github.com/h6ah4i/android-advancedrecyclerview/tree/develop considering the expand animated view indicator !!!! understanding the data provider takes lot of efforts!!
