Answer 1

I just ran into the same problem today. As the previous answers indicate, the problem stems from the use of a color in the divider tag, rather than a drawable. However, instead of writing my own drawable xml, I prefer to use themed attributes as much as possible. You can use the android:attr/dividerHorizontal and android:attr/dividerVertical to get a predefined drawable instead:

The attributes are available in API 11 and above.

Also, as mentioned by bocekm in his answer, the dividerPadding property does NOT add extra padding on either side of a vertical divider, as one might assume. Instead it defines top and bottom padding and thus may truncate the divider if it's too large.
