Answer 1

First, you have to set android:rating="0.0" to your RatingBar in xml. Then on button click check,

RatingBar ratingbar = (RatingBar)findViewById(R.id.ratingBar);
@Override
    public void onClick(View view) {
        switch (view.getId()){
            case R.id.ratingBar:
                 if(ratingbar.getRating() == 0.0){

                    //set what you want
                     }else{

                    //give error if ratingbar not changed
                     }
            break;
    }
}

Answer 2

Implement the onRatingBarChangeListener and place the intent for the new activity inside it:

    ratingBar.setOnRatingBarChangeListener(new OnRatingBarChangeListener() {
        public void onRatingChanged(RatingBar ratingBar, float rating,
            boolean fromUser) {

            // place intent for new activity

        }
    });

Use the RatingBar.getRating() method to get the current rating. If it returns zero, then prompt the user to rate your app with a toast.
