        String motion =buttonView.getText().toString();
        if(isChecked){
            if(!hobby.contains(motion)){
                hobby = hobby + motion;
            }
        }else {
            if(hobby.contains(motion)){
 
              hobby=hobby.replace(motion,"");
            }
 
        }
}
 
}
