Notification.Action
public static class Notification.Action
extends Object
implements Parcelable
Structure to encapsulate a named action that can be shown as part of this notification. It must include an icon, a label, and a PendingIntent
to be fired when the action is selected by the user.
结构封装一个命名的行动,可以显示为这个通知的一部分。它必须包含一个图标,标签和PendingIntent被解雇时,行动是由用户选定。
Apps should use addAction(int, CharSequence, PendingIntent)
or addAction(Notification.Action)
to attach actions.

Public methods
clone
Notification.Action clone ()
Creates and returns a copy of this object. The precise meaning of "copy" may depend on the class of the object. The general intent is that, for any objectx
, the expression:
will be true, and that the expression:x.clone() != x
will bex.clone().getClass() == x.getClass()
true
, but these are not absolute requirements. While it is typically the case that:will bex.clone().equals(x)
true
, this is not an absolute requirement.By convention, the returned object should be obtained by calling super.clone
. If a class and all of its superclasses (except Object
) obey this convention, it will be the case that x.clone().getClass() == x.getClass()
.
By convention, the object returned by this method should be independent of this object (which is being cloned). To achieve this independence, it may be necessary to modify one or more fields of the object returned by super.clone
before returning it. Typically, this means copying any mutable objects that comprise the internal "deep structure" of the object being cloned and replacing the references to these objects with references to the copies. If a class contains only primitive fields or references to immutable objects, then it is usually the case that no fields in the object returned by super.clone
need to be modified.
The method clone
for class Object
performs a specific cloning operation. First, if the class of this object does not implement the interface Cloneable
, then a CloneNotSupportedException
is thrown. Note that all arrays are considered to implement the interface Cloneable
and that the return type of theclone
method of an array type T[]
is T[]
where T is any reference or primitive type. Otherwise, this method creates a new instance of the class of this object and initializes all its fields with exactly the contents of the corresponding fields of this object, as if by assignment; the contents of the fields are not themselves cloned. Thus, this method performs a "shallow copy" of this object, not a "deep copy" operation.
The class Object
does not itself implement the interface Cloneable
, so calling the clone
method on an object whose class is Object
will result in throwing an exception at run time.
Notification.Action
a clone of this instance.describeContents
int describeContents ()
Describe the kinds of special objects contained in this Parcelable instance's marshaled representation. For example, if the object will include a file descriptor in the output of writeToParcel(Parcel, int)
, the return value of this method must include the CONTENTS_FILE_DESCRIPTOR
bit.
int
a bitmask indicating the set of special object types marshaled by this Parcelable object instance.getAllowGeneratedReplies
boolean getAllowGeneratedReplies ()
Return whether the platform should automatically generate possible replies for this Notification.Action
boolean
getExtras
Bundle getExtras ()
Get additional metadata carried around with this Action.
Bundle
getIcon
Icon getIcon ()
Return an icon representing the action.
Icon
getRemoteInputs
RemoteInput[] getRemoteInputs ()
Get the list of inputs to be collected from the user when this action is sent. May return null if no remote inputs were added.
RemoteInput[]
writeToParcel
void writeToParcel (Parcel out, int flags)
Flatten this object in to a Parcel.
out
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
