The notification rating has been modified. The client can use the fromUser parameter to distinguish between user-triggered changes and programming-triggered changes. When you drag a user, the user will not be called continuously, but will be called only when the user finally leaves the touch to end the score.

RatingBar

Rating current score. The value range is 0 to the number of stars.

FromUser returns true if the score change is triggered by the movement of the user's touch gesture or direction key trackball.
