Rating

public final class Rating
extends Object implements Parcelable

java.lang.Object
   ↳ android.media.Rating


A class to encapsulate rating information used as content metadata. A rating is defined by its rating style (see RATING_HEART, RATING_THUMB_UP_DOWN, RATING_3_STARS, RATING_4_STARS, RATING_5_STARS or RATING_PERCENTAGE) and the actual rating value (which may be defined as "unrated"), both of which are defined when the rating instance is constructed through one of the factory methods.
