Class Overview
A gesture is a hand-drawn shape on a touch screen. It can have one or multiple strokes.
Each stroke is a sequence of timed points. A user-defined gesture can be recognized by
a GestureLibrary.

public
void
addStroke
(GestureStroke stroke)
Adds a stroke to the gesture.
public
Object
clone
()
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.
public
int
describeContents
()
Describe the kinds of special objects contained in this Parcelable's
marshalled representation.
Returns
- a bitmask indicating the set of special object types marshalled
by the Parcelable.
public
RectF
getBoundingBox
()
Returns
- the bounding box of the gesture
public
float
getLength
()
Calculates the total length of the gesture. When there are multiple strokes in
the gesture, this returns the sum of the lengths of all the strokes.
Returns
- the length of the gesture
Returns
- all the strokes of the gesture
public
int
getStrokesCount
()
Returns
- the number of strokes included by this gesture
public
Bitmap
toBitmap
(int width, int height, int edge, int numSample, int color)
Creates a bitmap of the gesture with a transparent background.
Parameters
width
| width of the target bitmap |
height
| height of the target bitmap |
edge
| the edge |
public

writeToParcel
(Parcel out, int flags)
Flatten this object in to a Parcel.
Parameters
out
| The Parcel in which the object should be written. |

| Additional flags about how the object should be written.
May be 0 or PARCELABLE_WRITE_RETURN_VALUE .
