title: Banner - is there a built-in view?
body: <p>Is there an existing <code>View</code> in <code>Android</code> for a <a href="https://material.io/design/components/banners.html" rel="noreferrer">banner</a>? Or do I need to build one myself using the <a href="https://material.io/design/components/banners.html#specs" rel="noreferrer">specs</a>?<br>
  To be clear, this is not for ads but for the <code>Material-Design</code> concept of <code>Banner</code>.</p>
