↳ | android.view.WindowAnimationFrameStats |
This class contains window animation frame statistics. For example, a window
animation is usually performed when the application is transitioning from one
activity to another. The frame statistics are a snapshot for the time interval
from getStartTimeNano()
to getEndTimeNano()
.
The key idea is that in order to provide a smooth user experience the system should
run window animations at a specific time interval obtained by calling getRefreshPeriodNano()
. If the system does not render a frame every refresh
period the user will see irregular window transitions. The time when the frame was
actually presented on the display by calling getFramePresentedTimeNano(int)
.

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.
Returns | |
---|---|
int |
a bitmask indicating the set of special object types marshaled by this Parcelable object instance. |
String toString ()
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())
Returns | |
---|---|
String |
a string representation of the object. |
void writeToParcel (Parcel parcel, int flags)
Flatten this object in to a Parcel.
Parameters | |
---|---|
parcel |
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 .
