Question

I am new to Java and Andriod development.

I have a view within my app which contains a ListView

I then have a custom Adapter which inherits from an ArrayAdapter

within the view in the getView method I return a row which contains some text and a checkbox

now so far this all works great my list is populated and I can check my items, and all the events seem to fire as expected.

My problem that I am having is that I check the first 3 items and then I notice that the 11th, 12th and 13th items are checked and as I scroll I see that at regular intervals other checkboxes also seem to be checked in the same pattern.

If I check about 10 checkboxes then it will end up checking all the items in the list of about 80…

can anyone explain what I have done wrong?

I dont think any code will help explain this as I do not set the checkstate of the checkbox anywhere, this is all handled itself, so the fact items are being checked is puzzling me.

Thanks in advance

This is happening because Android recycles list items for performance purposes, here you have the solution of this problem:
ListView reusing views when … I don't want it to
