Thanks for your pull request. It looks like this may be your first contribution to a Google open source project. Before we can look at your pull request, you'll need to sign a Contributor License Agreement (CLA).

📝 Please visit https://cla.developers.google.com/ to sign.

Once you've signed, please reply here (e.g. I signed it!) and we'll verify. Thanks.

• If you've already signed a CLA, it's possible we don't have your GitHub username or you're using a different email address. Check your existing CLA data and verify that your email is set on your git commits.
• If your company signed a CLA, they designated a Point of Contact who decides which employees are authorized to participate. You may need to contact the Point of Contact for your company and ask to be added to the group of authorized contributors. If you don't know who your Point of Contact is, direct the project maintainer to go/cla#troubleshoot.
• In order to pass this check, please resolve this problem and have the pull request author add another comment and the bot will run again.

This LGTM. I think we can merge this into 2.1.1. (Not sure how we missed this for 2.1.0)

Since we are adding the style, we can remove all of the following:

android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="end"

@TheCraftKid I was waiting on the CLA, which was never signed by @kayzenkayzen.

If it remains unsigned we can just replicate this PR ourselves.

[SUPERCILEX]

To whoever does this PR: we should also probably change the gravity to be end instead of right and we can also remove this unessassary string.

[WillieCubed]

Whoops, didn't notice the unsigned CLA. I think we should give this until next Monday or Tuesday and then replicate the PR.
