There are many causes for this but I think it's safe to say something has gone wrong with your theming if this issue occurs.

For me I was defining a theme: android:theme="@style/myTheme" on a Button, and myTheme foolishly had a parent of parent="TextAppearance.AppCompat.Button" due to a copy paste error. That means it could not find button-y related resources. The fix was to make the parent the standard button theme: parent="@style/Widget.AppCompat.Button".

In the OP, I would guess that android:theme="@style/TextLabel" has a parent that is something unrelated. There really should be some lint warnings around these, styles are crazy complicated.
