Did you set the theme above the preview (dropdown next to the device e.g Nexus 5). — Vucko, Jul 15 '16 at 11:59
and also there is no error.. its only display rendring issue,, when you initialize on java class.. it will be solved.. just ignore it.. — Sagar Chavada, Jul 15 '16 at 12:35
Is it just a problem on the preview? Is it working on the device? If it works in the device why do you care about the preview? — Xaver Kapeller, Jul 15 '16 at 12:45
@XaverKapeller It does not work when I launch it, see the error I added below — Jason, Jul 15 '16 at 12:49
According to the error in your logcat the problem is something about your CoordinatorLayout. It has nothing to do with themes: `View can not be anchored to the the parent CoordinatorLayout`. — Xaver Kapeller, Jul 15 '16 at 12:51
To be more specific this is the problem: `app:layout_anchor="@id/myCoordinatorLayout"` — Xaver Kapeller, Jul 15 '16 at 12:52
Possible duplicate of [View can not be anchored to the the parent CoordinatorLayout](http://stackoverflow.com/questions/35747736/view-can-not-be-anchored-to-the-the-parent-coordinatorlayout) — Bill, Jul 15 '16 at 12:53
Why are you trying to anchor a view to the `CoordinatorLayout` itself? What's that supposed to do? I assume you actually want to anchor the button to the `AppBarLayout`, right? Then give the `AppBarLayout` an id and refer to it in the `app:layout_anchor` attribute. — Xaver Kapeller, Jul 15 '16 at 12:54
So in the future: Actually read the stack trace, it tells you everything you need to know. — Xaver Kapeller, Jul 15 '16 at 12:55
@XaverKapeller it worked!! Thank you! I just added an ID to the appbarlayout and it worked! — Jason, Jul 15 '16 at 13:02
I can't speak to that, I can just tell you that this is wrong and that the open source app doesn't use that as well. — Xaver Kapeller, Jul 15 '16 at 13:02

The solution is:

According to @XaverKapeller "Then give the AppBarLayout an id and refer to it in the app:layout_anchor attribute."

This solution worked
Thank you @XaverKapeller
