I want to know how to add certain values from a RecyclerView.
in case it will be model.getQntd() , I need to add all their respective results.
UPDATE
I've been able to count the problem now is that when there happens a change in the server (firebase), the sum increments a new number instead of modifying ... Example its I have 2 values in the example server :.
}
teste1:
qntd:10
}
...
}
teste2:
qntd:10
}
If I change the qntd from teste1 to 11 , the result will be, 10 + 10 + 11 = 31 and not 21 , since 10+10 has already been added to the list and 11 comes as a new data ... if I go out and return to activity the result will be 21 ...
Thank you in advance.
