TvContentRating

public final class TvContentRating
extends Object

java.lang.Object
   ↳ android.media.tv.TvContentRating


A class representing a TV content rating. When a TV input service inserts the content rating information on a program into the database, this class can be used to generate the formatted string for TvContract.Programs.COLUMN_CONTENT_RATING. To create a TvContentRating object, use the TvContentRating.createRating method with valid rating system string constants.

It is possible for an application to define its own content rating system by supplying a content rating system definition XML resource (see example below) and declaring a broadcast receiver that filters ACTION_QUERY_CONTENT_RATING_SYSTEMS in its manifest.

Example: Rating system definition for the TV Parental Guidelines

The following XML example shows how the TV Parental Guidelines in the United States can be defined:

 <rating-system-definitions xmlns:android="http://schemas.android.com/apk/res/android"
     android:versionCode="1">
     <rating-system-definition android:name="US_TV"

System defined rating strings

The following strings are defined by the system to provide a standard way to create TvContentRating objects.

For example, to create an object that represents TV-PG rating with suggestive dialogue and coarse language from the TV Parental Guidelines in the United States, one can use the following code snippet:

 TvContentRating rating = TvContentRating.createRating(
         "com.android.tv",
         "US_TV",
         "US_TV_PG",
         "US_TV_D", "US_TV_L");

Inherited methods

From class java.lang.Object

Fields

UNRATED

added in API level 23
TvContentRating UNRATED

Rating constant denoting unrated content. Used to handle the case where the content rating information is missing.

TV input services can call isRatingBlocked(TvContentRating) with this constant to determine whether they should block unrated content. The subsequent call to notifyContentBlocked(TvContentRating) with the same constant notifies applications that the current program content is blocked by parental controls.

Public methods

contains

added in API level 24
boolean contains (TvContentRating rating)

Returns true if this rating has the same main rating as the specified rating and when this rating's sub-ratings contain the other's.

For example, a TvContentRating object that represents TV-PG with S(Sexual content) and V(Violence) contains TV-PG, TV-PG/S, TV-PG/V and itself.

Parameters
rating TvContentRating: The TvContentRating to check.

This value must never be null.

Returns
boolean true if this object contains rating, false otherwise.

createRating

added in API level 21
TvContentRating createRating (String domain, 
                String ratingSystem, 
                String rating, 
                String... subRatings)

Creates a TvContentRating object with predefined content rating strings.

Parameters
domain String: The domain string. For example, "com.android.tv".

ratingSystem String: The rating system string. For example, "US_TV".

rating String: The content rating string. For example, "US_TV_PG".

subRatings String: The sub-rating strings. For example, "US_TV_D" and "US_TV_L".

Returns
TvContentRating A TvContentRating object.

Throws
IllegalArgumentException If domain, ratingSystem or rating is null.

equals

added in API level 21
boolean equals (Object obj)

Indicates whether some other object is "equal to" this one.

The equals method implements an equivalence relation on non-null object references:

  • It is reflexive: for any non-null reference value x, x.equals(x) should return true.
  • It is symmetric: for any non-null reference values x and y, x.equals(y) should return true if and only if y.equals(x) returns true.
  • It is transitive: for any non-null reference values x, y, and z, if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.
  • It is consistent: for any non-null reference values x and y, multiple invocations of x.equals(y) consistently return true or consistently return false, provided no information used in equals comparisons on the objects is modified.
  • For any non-null reference value x, x.equals(null) should return false.

The equals method for class Object implements the most discriminating possible equivalence relation on objects; that is, for any non-null reference values x and y, this method returns true if and only if x and y refer to the same object (x == y has the value true).

Note that it is generally necessary to override the hashCode method whenever this method is overridden, so as to maintain the general contract for the hashCode method, which states that equal objects must have equal hash codes.

Parameters
obj Object: the reference object with which to compare.

Returns
boolean true if this object is the same as the obj argument; false otherwise.

flattenToString

added in API level 21
String flattenToString ()

Returns a string that unambiguously describes the rating information contained in a TvContentRating object. One can later recover the object from this string through unflattenFromString(String).

Returns
String a string containing the rating information, which can later be stored in the database.

getDomain

added in API level 21
String getDomain ()

Returns the domain of this TvContentRating object.

Returns
String

getMainRating

added in API level 21
String getMainRating ()

Returns the main rating of this TvContentRating object.

Returns
String

getRatingSystem

added in API level 21
String getRatingSystem ()

Returns the rating system of this TvContentRating object.

Returns
String

getSubRatings

added in API level 21
List<String> getSubRatings ()

Returns the unmodifiable sub-rating string List of this TvContentRating object.

Returns
List<String>

hashCode

added in API level 21
int hashCode ()

Returns a hash code value for the object. This method is supported for the benefit of hash tables such as those provided by HashMap.

The general contract of hashCode is:

  • Whenever it is invoked on the same object more than once during an execution of a Java application, the hashCode method must consistently return the same integer, provided no information used in equals comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
  • If two objects are equal according to the equals(Object) method, then calling the hashCode method on each of the two objects must produce the same integer result.
  • It is not required that if two objects are unequal according to the equals(java.lang.Object) method, then calling the hashCode method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.

As much as is reasonably practical, the hashCode method defined by class Object does return distinct integers for distinct objects. (This is typically implemented by converting the internal address of the object into an integer, but this implementation technique is not required by the Java™ programming language.)

Returns
int a hash code value for this object.

unflattenFromString

added in API level 21
TvContentRating unflattenFromString (String ratingString)

Recovers a TvContentRating object from the string that was previously created from flattenToString().

Parameters
ratingString String: The string returned by flattenToString().

Returns
TvContentRating the TvContentRating object containing the domain, rating system, rating and sub-ratings information encoded in ratingString.
