Hello, I've been hitting a wall with how to get a listener on the checkbox in my listview. Could someone give me an example of how to do it in this case? When this screen is displayed it pulls the data from the database and displays in in a listview. The checkbox status is set in filldata based on values from the database. I want to be able to select/deselect checkboxes in the list and write the changes back to the database as the end result. SO I'm thinking the first step is to get a listener on the checkboxes. At this point I can't even click on the list, but can click the checkbox on and off. Here are my xml layouts and java code. Thanks, Ryan.
