They do, but your hanging the wrong things on the hooks =).
Here's the general process for binding your data to a list view.
Create a custom class that is your data model that will be represented in
your UI. It has the properties you care about displaying in the list. In
this case, the text and color.
class MyType
{
String Text;
int Color;
}
Your ListAdapter is typed using your custom class.
ArrayAdapter<MyType> adapter = new ArrayAdapter<MyType>();
Then in your getView():
MyType selection = getItem(position);
CustomViewToReturn view = convertview != null convertView :
inflateFromXML(my_view_layout);
populateViewWithSelection(selection, view); // Set text and color on the
view using your object's state
return view;
