No resource found that matches the given name (at 'paddingBottom' with value '@dimen/ activity_vertical_margin')

Question

I was trying to build a navigation drawer for which I copied code from some website and I am getting this error in one of the XMLs.

No resource found

Answer 1

1. Go to Android view of the project
2. go to app -> res -> values.
3. Right click on values
4. Then "New" (right at the top of the pop-up menu), "Value resource file".
5. In the "file name" space, type "dimens.xml" (without the quotation marks " ")
6. Then simply "Ok".

Click on the newly created "dimens.xml" file. Remove all code in it and paste the following:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <dimen name="activity_vertical_margin">8dp</dimen>
    <dimen name="activity_horizontal_margin">8dp</dimen>
</resources>

that's should work

Answer 2

Make sure you copied the dimens.xml file too.

Answer 3

In some project templates you find app/src/main/res/values/dimens.xml with only one value:

<resources>
    <dimen name="fab_margin">16dp</dimen>
</resources>

So you need to add the missing ones to that file:

<resources>
    <dimen name="fab_margin">16dp</dimen>
    <dimen name="activity_horizontal_margin">16dp</dimen>
    <dimen name="activity_vertical_margin">16dp</dimen>
</resources>

Hope this helps.
