How can I prevent the action bar from locking?

Question

All the applications that I created turned off my action bar after I upgraded my phone to Marshmallow. The app works great on Lollipop and Kitkat.

Basically the application has one view and it does not display correctly on my updated phone.

EDIT: I tried android: fitsSystemWindows and this is what I get: With android: fitsSystemWindows

Use android:fitsSystemWindows="true"in the root representation of your layout.

android:fitsSystemWindows - , . true, , . , .

<item name="android:fitsSystemWindows">true</item>
