}
in my activity and recuclerAdapter is not null in my project
this is for example
recyclerAdapter = new RecyclerAdapter(BaseActivity.getContext(), null, null, null, null, null);
LinearLayoutManager linearLayoutManager = new LinearLayoutManager(BaseActivity.getContext());
linearLayoutManager.setOrientation(LinearLayout.VERTICAL);
recyclerView.setLayoutManager(linearLayoutManager);
recyclerView.setAdapter(recyclerAdapter);
Inside the return.What amount to put To show all the cells.

Answer 1

I think you can use it like this:
#Override
public int getItemCount() {
return 2;
}
