How to do something when a checkbox change state?

Question

This is my code:

Answer 1

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

    int id = buttonView.getId();

    if(isChecked){
       switch(id){
          case R.id.sprint:
          //add to database
          ...
       }
    }
    else{
      switch(id){
          case R.id.sprint:
          //remove from database
          ...
       }
   }
}

This should allow you to with ID's. Hope it works.
