title: best practices for handling UI events
body: <p>I have put the all the binding code for UI events on OnCreate(). It has made my OnCreate() huge. </p>
  
  <p>Is there pattern around implementing UI events in android ? Can I add methods in View xml file and then I can put all the handler code somewhere else.</p>
  
  <p>In a nutshell , I think I am asking how can I implement MVVM pattern with android app code ?</p>
