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.

Fields

public static final Creator<Gesture> CREATOR

Added in API level 4

Public Constructors

public Gesture ()

Added in API level 4

Public Methods

public void addStroke (GestureStroke stroke)

Added in API level 4

Adds a stroke to the gesture.

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 int describeContents ()

Added in API level 4

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 ()

Added in API level 4

Returns
  • the bounding box of the gesture

public long getID ()

Added in API level 4

Returns
  • the id of the gesture

public float getLength ()

Added in API level 4

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

public ArrayList<GestureStroke> getStrokes ()

Added in API level 4

Returns
  • all the strokes of the gesture

public int getStrokesCount ()

Added in API level 4

Returns
  • the number of strokes included by this gesture

public Bitmap toBitmap (int width, int height, int edge, int numSample, int color)

Added in API level 4

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
Returns
  • the bitmap

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

Added in API level 4

Creates a bitmap of the gesture with a transparent background.

Returns
  • the bitmap

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

Added in API level 4

public Path toPath (Path path)

Added in API level 4

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

Added in API level 4

public Path toPath ()

Added in API level 4

public void writeToParcel (Parcel out, int flags)

Added in API level 4

Flatten this object in to a Parcel.

Parameters
out The Parcel in which the object should be written.
flags Additional flags about how the object should be written. May be 0 or PARCELABLE_WRITE_RETURN_VALUE.
No examples for this method.
