Android: Create spinner programmatically from array

I'm all new to Android and I'm trying to create a spinner programmatically and feeding it with data from an array, but Eclipse gives me a warning that I can't handle.

Here's what I got:

This ArrayList holds the elements that should be in the spinner (gets filled from a file later on):

ArrayList<String> spinnerArray = new ArrayList<String>();

This is code I found on a site which should create the spinner:

Spinner spinner = new Spinner(this);
ArrayAdapter spinnerArrayAdapter = new ArrayAdapter(this,

Now the second line (ArrayAdapter...) gives me a warning in Eclipse saying
"ArrayAdapter is a raw type... References to generic type ArrayAdapter<T> should be parameterized"
, I have no idea how to fix this (or what that means in the first place :) ).

It's just a warning and the App seems to run alright, but I'd still like to understand what's wrong and fix it. Any hint is appreciated.

ArrayAdapter<String> should work.


Spinner spinner = new Spinner(this);
ArrayAdapter<String> spinnerArrayAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item, spinnerArray); //selected item will look like a spinner set from XML
