Let's use standard android.support.v7.widget.Toolbar

[Ian Wen, 2015/08/12 00:09:26]

Done. Thanks for the advice. It indeed looks nicer with toolbar (such as the
back button now has a round ripple).

Q: what do we need this for?

[Ian Wen, 2015/08/12 00:09:26]

This is needed for letting the edittext get focus, as part of the effort to show
the keyboard when the search view is launched.
