Get correct id for checkbox for update value in SQlite

I have trouble getting right on my checkbox . My problem is that I do not get the correct id from the database and therefore do not know the ID / series I will update the database. I have tried various suggestions here , but nothing would work. For the most part , I notice that the index is out of ...

When I used ArrayList to collect information, it was easy. I just used int position from my View to get the id...

I deleted all my attempts , therefore , there is currently no direct code that tries to solve the problem.

Thanks in advance
