The reason why this works:

<item name="cardBackgroundColor">@color/cardview_light_background</item>

But this doesn't:

<item name="middleBarArrowSize">16.0dip</item>

Is because cardBackgroundColor is declared in the android.support.v7.cardview package, which your project will have a dependency on. This can easily be confirmed if you open up:

<sdk_path>/extras/android/support/v7/cardview/res/values/attrs.xml

Amongst others, you'll find:

<resources>
    <declare-styleable name="CardView">
        <!-- Background color for CardView. -->
        <attr name="cardBackgroundColor" format="color" />
        ...
    </declare-styleable>
</resources>

Based on the code you've given, middleBarArrowSize hasn't been declared anywhere yet. In order to use a custom attribute, you have to declare it first (similar to above).

This process is explained in the docs here and will result in something like this:

res/values/attrs.xml

<resources>
   <declare-styleable name="MyCustomAttributes">
       <attr name="middleBarArrowSize" format="dimension" />
       <attr name="topBottomBarArrowSize" format="dimension" />
       <attr name="disableChildrenWhenDisabled" format="boolean" />
       <!-- add more here -->
   </declare-styleable>
</resources>

After having done that, you should be able to use the declared attributes in your project.

but in colors.xml I have declared value like (...)

There is a difference between attributes and colors. A color is a value, whereas an attribute is something you can assign a value to (i.e. a color, or a string, etc).

In case some resource not found for example

compile "com.android.support:cardview-v7:23.2.0"

At this time first you check values-v24 and your build.gradle

dependencies {
    compile "com.android.support:support-v4:24.2.0"
    compile "com.android.support:support-v13:24.2.0"
    compile "com.android.support:cardview-v7:24.2.0"
}

If your file name version and dependencies api version same then you can resolve this type of error easily.

For example

com.android.support:cardview-v7:24.2.0 is OK for values-v24 res folder

No resource found that matches the given name: attr 'middleBarArrowSize'
