Correct me if I'm wrong, but I assume you are referring to Build a Simple Android App course and the textSize value of 24sp. You could create integer resource files just like string ones but in this case it wouldn't work since it is 24sp and not just integer 24. What you could do is to add another entry in the dimens.xml file as follows:

<resources>
    <!-- Default screen margins, per the Android Design guidelines. -->
    <dimen name="activity_horizontal_margin">50dp</dimen>
    <dimen name="activity_vertical_margin">50dp</dimen>
    <!-- Default text size. -->
    <dimen name="text_size">24sp</dimen>
</resources>

Then in the layout file you can refer to it as:

<TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Did you know?"
        android:textSize="@dimen/text_size"
        android:textColor="#80ffffff"/>

I am not exactly sure what you want to solve... but if you want to store numbers in a variable then you can do this: E.g: If you want to store a number value 5 in a variable then you can do it so by: int numberValue = 5;

Here int is a datatype, numberValue is the name of the variable that holds the value 5. Now you can use numberValue to pass the value 5.

Hope it helps!

Happy Coding!
