@navylover Cannot resolve symbol '?attr/actionBarSize' less... Validates resource references inside Android XML files. – Pouria Hemi Sep 17 '18 at 09:15

You should use
?android:attr/actionBarSize
XML
android:layout_height="?android:attr/actionBarSize"

You can use the ?attr/actionBarSize still, the issue is that Android Studio is showing error on ?attr/actionBarSize. Almost every android developer has faced this issue in AS 3+.
Solution
- Close project
- Open project again (not from recent)
Resolved! :)
By the way, all below works still
android:layout_height="?actionBarSize"
android:layout_height="?android:actionBarSize"
android:layout_height="?attr/actionBarSize"

You should use this
android:layout_height="?android:attr/actionBarSize"
instead of
android:layout_height="?attr/actionBarSize"
