body: <p>I have googled a lot but still don't find an answer. </p>
  
  <p>I want to create a keyboard style like this:</p>
  
  <p><img src="https://i.stack.imgur.com/VM8gG.png" alt="enter image description here"></p>
  
  <p>You see that the left most keys are in a special column and it can be scrolled when my finger move up and down. </p>
  
  <p>How should I write my keyboard layout and inflate it in java code ? Thanks </p>
