title: Android: How to use Buttons in Preference Screen
body: <p>I'd like to provide a Button in the PreferenceActivity. The user should be able to set a
  time (e.g. via TimePicker), but there's no ButtonPreference or something like that. I don't want to use EditTextPreference.</p>
  
  <p>So do I have to use a default Button in the PreferenceActivity and save the settings for it manually?</p>
  
  <p>Regards,</p>
