 rate = (TextView) findViewById(R.id.puan);
        rb = (RatingBar) findViewById(R.id.ratingBar);
        rb.setOnRatingBarChangeListener(new RatingBar.OnRatingBarChangeListener() {
            @Override
            public void onRatingChanged(RatingBar ratingBar, float rating, boolean b) {
                final float numStars = ratingBar.getRating();
                editor = wm.edit();
                editor.putFloat("numStars", rating);
                editor.commit();
                float ratings = wm.getFloat("numStars", 0);
                rate.setText(rating + "/" + String.valueOf(ratings));
            }
        });

A quick google search asking for Android RatingBar documentation took me to this page: https://developer.android.com/reference/android/widget/RatingBar

A quick look through the page led me to find the following info:

void setMax(int max);
//Set the upper range of the progress bar max.

void setMin(int min);
//Set the lower range of the progress bar min.
