title: OnclickListener vs OnClick
body: <p>I am learning how to develop apps in Android Studio and have just begun.
  I learnt 2 methods of handling button click events. One is to implement OnClickListener while the other is to go to XML and just use Android:OnClick. The second method is far easier for me. Is there any advantage of the first method or is just knowing the second method enough?</p>
  
  <p>Thanks
