Why does the content go beyond the ActionBar?

Question

Android

I want to change the look of one application a little. Faced such a problem, the list (and indeed everything) goes beyond the action bar.
Why is this happening? In which direction to dig?
It seems that I looked at a few instructions on how to do it right, and I also looked at StackOverflow - still nothing helps, it feels like there is some kind of small subtlety in this matter that I just can’t catch.

Answer 1

The error is somewhere in the code.

Answer 2

Is it Lollipop?
If yes, then you need to set ActionBar-a

<!-- Set AppCompat’s color theming attrs -->
    <item name=”colorPrimary”>@color/my_awesome_red</item>
    <item name=”colorPrimaryDark”>@color/my_awesome_darker_red</item>

Answer 3

Are you using standard Android features or are you using some third party library? Give an example of an xml file with markup. If you use styles and theme customization, then you should also look.
