Apps ListView Help: Resource Not Found

[piper210]

Hi people.

I am working on a project an am currently blocked. I created an arraylist with the info I want displayed in the listview. I used an array adapter and put that in the setListAdapter. All this is done by the book.

However, when I run it, it goes through the whole program and then gives me an error that it can't find the list_item.xml resource. I check the path that it gave an it is there. I tried cleaning the project and restarting the computer but nothing works.

Does anyone have any ideas as to how I can fix this? I'd really appreciate the help.

Additional Info: I have been doing tests and it I learned that the program messes up when I use setListAdapter(value).

fyi: The variable value is what i get from the array adapter.

Hope this info is useful. I really need some help to solve this. I honestly don't know what to try next.

where is your setcontentview() being called?

 

[piper210]

it extends listactivity so setContextView() doesn't have to be called.
It shouldn't effect the result event if it is there, but I tried putting it and it gave me an error.
