Android Recycler View Example – Multiple View Types | how to use two recycler view in android
What do you mean by combing RecyclerView's? Put a RecyclerView inside item of another RecyclerView? It is possible, many do this. Or you want to combine different data sources inside single RecyclerView? This is possible either, you have to create composite adapter and feed it with other adapters in case you have no access to data classes code, otherwise you can use delegation and create single adapter, feed it with ViewHolder’s you need and provide external view type selector for it, and you have to put marker interface on your data classes, or put your data objects inside containers to be able to store your data inside single collection, because you need stable positioning of items on screen. So yes, you can combine RecyclerView's and their data.
