?actionBarTheme for Toolbar seems not correct before change the theme

[tianma8023]

In the demo-main module, we can see that the DrawerActivity includes a Toolbar.

But when first run it (Don't change theme), the toolbar's text color seems not correct. Here are the screenshots:

It's okay, MainActivity don't use Toolbar.

The title text color of Toolbar and other menu icons color is black rather than white.
