NotificationRequest.NotificationMediaContent

java.lang.Object
- ohos.event.notification.NotificationRequest.NotificationMediaContent

所有已实现的接口:

Sequenceable

封闭类:

NotificationRequest
```
public static final class NotificationRequest.NotificationMediaContent
extends Object
implements Sequenceable
```
Constructs a media playback notification that can interact with associated audio sessions.
Before constructing this notification, you should first initialize a NotificationMediaContent object, and call setAVToken(ohos.media.common.sessioncore.AVToken) to attach an AVToken to it for setting up an interaction channel with the associated AVSession. You can call setShownActions(int[]) to request the NotificationActionButton objects to be displayed in this notification. Then, you should initialize a NotificationRequest object and call NotificationRequest#setContent(NotificationContent) to set it to a media playback notification and attach the previously constructed NotificationMediaContent object to it. Additionally, you should call NotificationRequest#addActionButton(NotificationActionButton) so that media control buttons will be displayed in this notification after it is published.

  - toString
```
public String toString()
```
    从类复制的说明: Object
    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())
    覆盖:
    
    toString 在类中 Object
    
    返回:
    
    a string representation of the object.
