I suggest you to set(in loop) for each CheckBox set OnCheckedChangeListener.

cb.setOnCheckedChangeListener(new OnCheckedChangeListener() {
   public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
      if (isChecked) {
         // do some action
      }     
   }
});

Now you are able to handle events for each CheckBox.

Just check cb.isChecked() which returns a boolean value.

you will need to set CompoundButton.OnCheckedChangeListener for CheckBox to fire an event when checkbox clicked. Example :

cb.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {

   @Override
   public void onCheckedChanged(CompoundButton buttonView,boolean isChecked) {

      // do your code here
   }
});
