Android :: CheckedTextView In A ListView?

I'm creating a view where it will list about 30 items, each with its own checkbox. I'm using the android.R.layout.simple_list_item_multiple_choice layout for this.

I have it displaying on the screen with my items and the checkboxes and it looks great. But here's the problem. When I click on one, it checkmarks, but when I scroll to the next page of items it shows the item in the exact same position is also checked.

Example of what I mean:

The emulator shows me 7 results on the screen at a time. If I click the checkbox for the first item, it enables. Then I scroll the screen down past the 7th item I see that the 8th item is checked, even though it shouldn't be. If I scroll down again to I see another item checked. The only one that should be checked is the one I actually clicked on. I can repeat this same exact problem for for any position in the item list. I must be doing something wrong in the code.

Here's my code -- not much to it:

Creating the adapter:

CODE:..........

I tried both ways in the above method. Both had the same result.
