Android - Unknown attribute style on a fragment tag

Question

Can someone please explain to me why I am getting this warning in Android Studio 1.1.0:

Unknown attribute style
Full warning: The inspection highlights unknown XML attributes in Android resource files and AndroidManifest.xml

Here is the code snippet:

<fragment
    android:id="@+id/frag_logo"
    tools:layout="@layout/fragment_logo"
    style="@style/FragmentLogo"/>

The warning occurs on the style attribute.

I am using gradle and android build tools 21.1.2

Answer 1

The style attribute is supported for Views (and by inheritance ViewGroups), so fragments don't support it.

Answer 2

For my configuration warning still exists but style works for fragments. Eventually fragments supply View on onCreateView() so style should work.
