That makes sense. Thanks.

I did :
MyAdapter<String> adapter = new
MyAdapter<String>(this,android.R.layout.simple_list_item_1, values);

For what it is worth, I can do this:
public View getView(int position, View convertView, ViewGroup parent) {
TextView text = new TextView(getContext());
text.setText("Hi, I am position " + position);
text.setTextColor(Color.parseColor("#64788e"));
return text;
}
That will set the text color to blue, but it will also change the text
I put in the list.

Is this example
http://developer.android.com/resources/tutorials/views/hello-listview.html
impossible to manipulate the color of individual list items? Or, is
there a way to patch up this code to do what I want? It seems pretty
trivial to do. I don't understand why the hooks do not exist for what
i want to do.
