GestureStroke

extends Object

java.lang.Object
↳	android.gesture.GestureStroke

Class Overview

A gesture stroke started on a touch down and ended on a touch up. A stroke consists of a sequence of timed points. One or multiple strokes form a gesture.

Summary

Fields
public final RectF	boundingBox
public final float	length
public final float[]	points

Public Constructors
	GestureStroke(ArrayList<GesturePoint> points) A constructor that constructs a gesture stroke from a list of gesture points.

Public Methods
void	clearPath() Invalidates the cached path that is used to render the stroke.
Object	clone() Creates and returns a copy of this `Object`.
OrientedBoundingBox	computeOrientedBoundingBox() Computes an oriented bounding box of the stroke.
Path	getPath()
Path	toPath(float width, float height, int numSample) Converts the stroke to a Path of a given number of points.

Inherited Methods

From class java.lang.Object

Object	clone() Creates and returns a copy of this `Object`.
boolean	equals(Object o) Compares this instance with the specified object and indicates if they are equal.
void	finalize() Invoked when the garbage collector has detected that this instance is no longer reachable.
final Class<?>	getClass() Returns the unique instance of `Class` that represents this object's class.
int	hashCode() Returns an integer hash code for this object.
final void	notify() Causes a thread which is waiting on this object's monitor (by means of calling one of the `wait()` methods) to be woken up.
final void	notifyAll() Causes all threads which are waiting on this object's monitor (by means of calling one of the `wait()` methods) to be woken up.
String	toString() Returns a string containing a concise, human-readable description of this object.
final void	wait() Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object.
final void	wait(long millis, int nanos) Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object or until the specified timeout expires.
final void	wait(long millis) Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object or until the specified timeout expires.

Public Constructors

public GestureStroke (ArrayList<GesturePoint> points)

Added in API level 4

A constructor that constructs a gesture stroke from a list of gesture points.

Public Methods

public void clearPath ()

Added in API level 4

Invalidates the cached path that is used to render the stroke.

public Object clone ()

Added in API level 4

Creates and returns a copy of this Object. The default implementation returns a so-called "shallow" copy: It creates a new instance of the same class and then copies the field values (including object references) from this instance to the new instance. A "deep" copy, in contrast, would also recursively clone nested objects. A subclass that needs to implement this kind of cloning should call super.clone() to create the new instance and then create deep copies of the nested, mutable objects.

Returns

a copy of this object.

public OrientedBoundingBox computeOrientedBoundingBox ()

Added in API level 4

Computes an oriented bounding box of the stroke.

Returns

OrientedBoundingBox

public Path getPath ()

Added in API level 4

public Path toPath (float width, float height, int numSample)

Added in API level 4

Converts the stroke to a Path of a given number of points.

Parameters

width	the width of the bounding box of the target path
height	the height of the bounding box of the target path
numSample	the number of points needed

Returns

the path
