Gesture

public class Gesture
extends Object implements Parcelable

java.lang.Object
↳	android.gesture.Gesture

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 methods

addStroke

public void addStroke (GestureStroke stroke)

Adds a stroke to the gesture.

clone

public Object clone ()

Creates and returns a copy of this object. The precise meaning of "copy" may depend on the class of the object. The general intent is that, for any object x, the expression:

 x.clone() != x

will be true, and that the expression:

 x.clone().getClass() == x.getClass()

will be true, but these are not absolute requirements. While it is typically the case that:

 x.clone().equals(x)

will be true, this is not an absolute requirement.

By convention, the returned object should be obtained by calling super.clone. If a class and all of its superclasses (except Object) obey this convention, it will be the case that x.clone().getClass() == x.getClass().

By convention, the object returned by this method should be independent of this object (which is being cloned). To achieve this independence, it may be necessary to modify one or more fields of the object returned by super.clone before returning it. Typically, this means copying any mutable objects that comprise the internal "deep structure" of the object being cloned and replacing the references to these objects with references to the copies. If a class contains only primitive fields or references to immutable objects, then it is usually the case that no fields in the object returned by super.clone need to be modified.

The method clone for class Object performs a specific cloning operation. First, if the class of this object does not implement the interface Cloneable, then a CloneNotSupportedException is thrown. Note that all arrays are considered to implement the interface Cloneable and that the return type of the clone method of an array type T[] is T[] where T is any reference or primitive type. Otherwise, this method creates a new instance of the class of this object and initializes all its fields with exactly the contents of the corresponding fields of this object, as if by assignment; the contents of the fields are not themselves cloned. Thus, this method performs a "shallow copy" of this object, not a "deep copy" operation.

The class Object does not itself implement the interface Cloneable, so calling the clone method on an object whose class is Object will result in throwing an exception at run time.

Returns
`Object`	a clone of this instance.

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`

getBoundingBox

public RectF getBoundingBox ()

Returns
`RectF`	the bounding box of the gesture

getID

public long getID ()

Returns
`long`	the id of the gesture

getLength

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
`float`	the length of the gesture

getStrokes

public ArrayList<GestureStroke> getStrokes ()

Returns
`ArrayList<GestureStroke>`	all the strokes of the gesture

getStrokesCount

public int getStrokesCount ()

Returns
`int`	the number of strokes included by this gesture

toBitmap

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`	`int`: width of the target bitmap
`height`	`int`: height of the target bitmap
`edge`	`int`: the edge

Returns
`Bitmap`	the bitmap

toBitmap

public Bitmap toBitmap (int width, 
                int height, 
                int inset, 
                int color)

Creates a bitmap of the gesture with a transparent background.

Returns
`Bitmap`	the bitmap

toPath

Parameters
`width`	`int`
`height`	`int`
`edge`	`int`
`numSample`	`int`

Returns
`Path`

toPath

public Path toPath (Path path, 
                int width, 
                int height, 
                int edge, 
                int numSample)

Parameters
`path`	`Path`
`width`	`int`
`height`	`int`
`edge`	`int`
`numSample`	`int`

Returns
`Path`

toPath

public Path toPath ()

Returns
`Path`

writeToParcel

public void writeToParcel (Parcel out, 
                int flags)

Flatten this object in to a Parcel.

Parameters
`out`	`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.PARCELABLE_WRITE_RETURN_VALUE`. Value is either `0` or a combination of `Parcelable.PARCELABLE_WRITE_RETURN_VALUE`, and android.os.Parcelable.PARCELABLE_ELIDE_DUPLICATES
