    Perhaps the `res/values/dimens.xml` file is missing in your project or doesn't include the expected identifiers(?) – Markus Kauppinen Aug 24 '18 at 10:53
  • As a quick solution remove all those lines . And read about [Android Resource structure](https://developer.android.com/guide/topics/resources/providing-resources) . – ADM Aug 24 '18 at 11:11

I suppose you copied all these lines from another project that you found online.
In the project where these lines originally come from there is a file dimens.xml in res folder which contains all these @dimen/... values. These are numeric values and they are used to set the padding of your Layout
You must copy this file in your project too or just delete the first 4 red underlined lines.
As for the 5th line you may leave it like this: 

tools.context=".MainActivity"

1) create dimens file It's located in res/values/dimens , here's what a sample of the file look like:

 <resources>
     <!-- Default screen margins, per the Android Design guidelines. -->
     <dimen name="activity_horizontal_margin">16dp</dimen>
     <dimen name="activity_vertical_margin">16dp</dimen>
 </resources>

2) Make activity context like this:

tools:context=".MainActivity"
