title: How to open a Dialog from a text entry on a PreferenceScreen?
body: <p>In my Android app I want to show a Dialog if the user selects on something that looks like plain text in a PreferenceScreen.  I have seen <a href="https://stackoverflow.com/questions/5456993/how-to-open-alertdialog-from-preference-screen">How to open AlertDialog from preference screen?</a>, but that solution launches from a CheckBoxPreference.</p>
  
  <p>In my case, I'd like to launch from something that looks like a TextView (or I suppose it could be a button), and it would then lead to an "About" dialog I already have.  Any suggestions how to do that?  Thanks.</p>
