title: Android: Reset Activity onClick
body: <p>I have an activity and on that activity there are a couple of buttons that do different things with numbers, etc. At a certain point though I would like to be able to have the user reset/(restart?) the activity back to the initial state without having the user have to hit the back button or restart the app.</p>
  
  <p>I want to create a reset button. I know how to make the button itself, but I do not the details of how to reset the activity.</p>
  
  <pre><code>@Override
  public void onClick(View v) {
      switch (v.getId()) {
      case R.id.button1:
          // do stuff
      break;
      case R.id.button2:
          // do stuff
          break;      
      case R.id.button3:
          // do stuff
          break;
      case R.id.reset:
          // what goes here?
      default:
          break;
      }
  }
  </code></pre>
  
  <p>How is this done?</p>
