How to select a radio value using espresso web

In my Android project, I have a webview. HTML source has 2 radio buttons. Using Espresso Web, I want to choose one of these 2. How do I do that?

For eg:

<input type="radio" value="City A" name="Location" id="Location">
<input type="radio" value="City B" name="Location" id="Location">

Thanks!
