title: looking for Android dialog widget with rounded corners
body: <p>I'm looking for an Android dialog component like this screenshot:</p>
  
  <p><a href="https://i.stack.imgur.com/3NEmk.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/3NEmk.png" alt="large dialog box with title and close button"></a></p>
  
  <p>Apologies for the white dialog on a white background but hopefully you can see the nice elevation shadow, the rounded corners, and importantly the close button on the top right of the dialog.
  (The screenshot is taken from a tab-less version of the Chrome app).</p>
  
  <p>Does anyone know of a library/snippet that achieves this, or something like it? Thanks.</p>
  
  <p><strong>edit:</strong>
  Some background info which hopefully will make the question clearer: I have a scrolling activity which has a lot of content - text and data - in which I would like to show further details/images via clickable text/image. Yes I could use an AlertDialog but I much prefer the look of the dialog window in the screenshot.</p>
