Android Spinner databind using array list

I have a array list like this:

private ArrayList<Locations> Artist_Result = new ArrayList<Location>();

This Location class has two properties: id and location.

I need to bind my ArrayList to a spinner. I have tried it this way:

Spinner s = (Spinner) findViewById(R.id.SpinnerSpcial);
ArrayAdapter adapter = new ArrayAdapter(this,android.R.layout.simple_spinner_item, Artist_Result);
s.setAdapter(adapter);

However, it shows the object's hexadecimal value. So I think I have to set display the text and value for that spinner controller.
