I haven't used ArrayAdapter, but I think the id is what is generated in R.java for your layout (i.e. R.layout.my_layout_xml.xml in your code).
If you are loading data into your spinner from a database, you probably wouldn't be using createFromResource. I think just use the constructor for ArrayAdapter if I understand the docs correctly.

layout file containing a TextView to use when instantiating views.
what does "ID for a layout file" mean ? A file does not have an ID. In the sample code, there is the following line:
ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(this, R.array.colors, android.R.layout.simple_spinner_item);
R.array.colors is an array defines in a file in the values directory. From all this I understand one cannot have a Spinner, for example, with data from a DB. There has to be a list of value defined in a resource file. If this is so, I find it stupid. If not, please tell me another way to build a Spinner. And another thing, it would be very useful for us, developers, to have a good help to reffer to.
