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

    I just wrote an answer explaining the whole process for using XML with custom UI elements. In your case, there is no need to declare a styleable, as you don’t need custom attributes. Using android.R.attr.prompt as the int id will work fine. R.styleable.className_attributeName will only work if you defined your attributes in the styleable and you retrieved them by passing R.styleable.className into obtainStyledAttributes.
