ratingBar = (RatingBar) findViewById(R.id.ratingBar);
ratingBar.setRating(3.5f);
ratingBar.setOnRatingBarChangeListener(new RatingBar.OnRatingBarChangeListener() {
 @Override
 public void onRatingChanged(RatingBar ratingBar, float rating, boolean fromUser) {
  if (fromUser) {//fromUser rating数量是否发生改变
   ratingBar.setRating(rating);

  Log.d(TAG, "rating=" + ratingBar.getRating());
  Log.d(TAG, "fromUser=" + fromUser);
