AbsSavedState


public abstract class AbsSavedState
extends Object implements Parcelable

java.lang.Object
   ↳ android.view.AbsSavedState
Preference.BaseSavedState This class was deprecated in API level 29. Use the AndroidX Preference Library for consistent behavior across all devices. For more information on using the AndroidX Preference Library see Settings. 
View.BaseSavedState Base class for derived classes that want to save and restore their own state in View.onSaveInstanceState()
TextView.SavedState User interface state that is stored by TextView for implementing View.onSaveInstanceState


A Parcelable implementation that should be used by inheritance hierarchies to ensure the state of all classes along the chain is saved.

Summary

Inherited constants

int CONTENTS_FILE_DESCRIPTOR

Descriptor bit used with describeContents(): indicates that the Parcelable object's flattened representation includes a file descriptor.

int PARCELABLE_WRITE_RETURN_VALUE

Flag for use with writeToParcel(Parcel, int): the object being written is a return value, that is the result of a function such as "Parcelable someFunction()", "void someFunction(out Parcelable)", or "void someFunction(inout Parcelable)".

Fields

public static final Creator<AbsSavedState> CREATOR

public static final AbsSavedState EMPTY_STATE

Protected constructors

AbsSavedState(Parcel source)

Constructor used when reading from a parcel.

AbsSavedState(Parcel source, ClassLoader loader)

Constructor used when reading from a parcel using a given class loader.

AbsSavedState(Parcelable superState)

Constructor called by derived classes when creating their SavedState objects

Public methods

int describeContents()

Describe the kinds of special objects contained in this Parcelable instance's marshaled representation.

final Parcelable getSuperState()
void writeToParcel(Parcel dest, int flags)

Flatten this object in to a Parcel.

Inherited methods

Object clone()

Creates and returns a copy of this object.

boolean equals(Object obj)

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

void finalize()

Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.

final Class<?> getClass()

Returns the runtime class of this Object.

int hashCode()

Returns a hash code value for the object.

final void notify()

Wakes up a single thread that is waiting on this object's monitor.

final void notifyAll()

Wakes up all threads that are waiting on this object's monitor.

String toString()

Returns a string representation of the object.

final void wait(long timeoutMillis, int nanos)

Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.

final void wait(long timeoutMillis)

Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.

final void wait()

Causes the current thread to wait until it is awakened, typically by being notified or interrupted.

abstract int describeContents()

Describe the kinds of special objects contained in this Parcelable instance's marshaled representation.

abstract void writeToParcel(Parcel dest, int flags)

Flatten this object in to a Parcel.

Fields

CREATOR

Added in API level 1
public static final Creator<AbsSavedState> CREATOR

EMPTY_STATE

Added in API level 1
public static final AbsSavedState EMPTY_STATE

Protected constructors

AbsSavedState

Added in API level 1
protected AbsSavedState (Parcel source)

Constructor used when reading from a parcel. Reads the state of the superclass.

Parameters
source Parcel: parcel to read from

AbsSavedState

Added in API level 24
protected AbsSavedState (Parcel source, 
                ClassLoader loader)

Constructor used when reading from a parcel using a given class loader. Reads the state of the superclass.

Parameters
source Parcel: parcel to read from

loader ClassLoader: ClassLoader to use for reading

AbsSavedState

Added in API level 1
protected AbsSavedState (Parcelable superState)

Constructor called by derived classes when creating their SavedState objects

Parameters
superState Parcelable: The state of the superclass of this view

Public methods

describeContents

Added in API level 1
public 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(android.os.Parcel, int), the return value of this method must include the CONTENTS_FILE_DESCRIPTOR bit.

Returns
int a bitmask indicating the set of special object types marshaled by this Parcelable object instance. Value is either 0 or CONTENTS_FILE_DESCRIPTOR

getSuperState

Added in API level 1
public final Parcelable getSuperState ()

Returns
Parcelable

writeToParcel

Added in API level 1
public 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. This value cannot be null.

flags int: Additional flags about how the object should be written. May be 0 or Parcelable.PARCELABLE_WRITE_RETURN_VALUE. Value is either 0 or a combination of Parcelable.PARCELABLE_WRITE_RETURN_VALUE, and android.os.Parcelable.PARCELABLE_ELIDE_DUPLICATES
