title: Android: Creating custom preference
body: <p>Is it possible to create an individual preference in an <code>PreferenceScreen</code>? </p>
  
  <p>I would like to code color settings like that:</p>
  
  <p><img src="https://i.stack.imgur.com/q4WLi.jpg" alt="Color Preference"></p>
  
  <p>I know that choosing the color is easy realizable with the <code>ListPreference</code>, but it would be awesome with that kind of "checkboxes".</p>
