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.

Summary

Constants
`int`	`RATING_3_STARS` A rating style with 0 to 3 stars.
`int`	`RATING_4_STARS` A rating style with 0 to 4 stars.
`int`	`RATING_5_STARS` A rating style with 0 to 5 stars.
`int`	`RATING_HEART` A rating style with a single degree of rating, "heart" vs "no heart".
`int`	`RATING_NONE` Indicates a rating style is not supported.
`int`	`RATING_PERCENTAGE` A rating style expressed as a percentage.
`int`	`RATING_THUMB_UP_DOWN` A rating style for "thumb up" vs "thumb down".

toString

Added in API level 19

String toString ()

Returns a string representation of the object. In general, the toString method returns a string that "textually represents" this object. The result should be a concise but informative representation that is easy for a person to read. It is recommended that all subclasses override this method.

The toString method for class Object returns a string consisting of the name of the class of which the object is an instance, the at-sign character `@', and the unsigned hexadecimal representation of the hash code of the object. In other words, this method returns a string equal to the value of:

 getClass().getName() + '@' + Integer.toHexString(hashCode())

Returns
`String`	a string representation of the object.

writeToParcel

Added in API level 19

void writeToParcel (Parcel dest, 
                int flags)

Flatten this object in to a Parcel.

Parameters
`dest`	`Parcel`: The Parcel in which the object should be written.
`flags`	`int`: Additional flags about how the object should be written. May be 0 or `PARCELABLE_WRITE_RETURN_VALUE`.
