source |
Parcel : parcel to read from |
AbsSavedState
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

Constructor called by derived classes when creating their SavedState objects
Parameters | |
---|---|
superState |
Parcelable : The state of the superclass of this view |
Public methods
describeContents
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 |
writeToParcel
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 |
