Question

I am working on a simple to-do list app, and on the main view I have a list of tasks with a checkmark aside to each, as the image below:

Upon clicking on the checkmark I want the respective task to be removed from the list. I tried to implement this as TextViews (for the tasks) and Buttons (for the checkmark), but I would need to know the number/position of the clicked checkmark (0,1,2 or 3) to remove the correct task from my array. Can I get this some how?

I also thought about implementing the tasks/checkmarks as a ListView, but then I would need to set a onItemClickListener only on the checkmark, and not on the task text. Is this possible?

Any other ideas? Thanks.

Checkbox has a tag property which you can use to set custom data like row number. Something like this should work,

checkbox.setTag(row_number);

So when you click on it, do something like

int rowNum = Integer.parseInt(checkbox.getTag());
removeTaskAt(rowNum);
