I've created a combo box control with a edittext and spinner. I'm trying to let the android:prompt attribute be passed onto the spinner, which means I need to catch it in the constructor which passes my the AttributeSet and set it on the spinner. I can't figure out how to get the value of the prompt. I'm trying,

int[] ra = { android.R.attr.prompt };
TypedArray ta = context.getTheme().obtainStyledAttributes(ra); 
int id = ta.getResourceId(0, 0); 

I get back 0, which means it didn't find the attribute. I also did a ta.count() which returned 0. So I'm not getting anything back.

My XML simply defines an android:prompt value.

Thanks
