title: Checkbox validation in Android
body: <p>I am developing an Android application where I have a screen with check boxes and a button (generated programmatically). I want to allow at most three check boxes to be checked when a user clicks on the button.</p>
  
  <p>I was hoping that there would be something like a check box group in Android, but unfortunately there isn't. </p>
  
  <p>Can anyone help me with this?</p>
