public class PathShape
extends Shape
java.lang.Object | ||
↳ | android.graphics.drawable.shapes.Shape | |
↳ | android.graphics.drawable.shapes.PathShape |
Creates geometric paths, utilizing the Path
class. The path can be drawn to a Canvas with its own draw() method, but more graphical control is available if you instead pass the PathShape to a ShapeDrawable
.

PathShape (Path path, float stdWidth, float stdHeight)
PathShape constructor.
Parameters | |
---|---|
path |
Path : a Path that defines the geometric paths for this shape |
stdWidth |
float : the standard width for the shape. Any changes to the width with resize() will result in a width scaled based on the new width divided by this width. |
stdHeight |
float : the standard height for the shape. Any changes to the height with resize() will result in a height scaled based on the new height divided by this height. |
PathShape 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:
will be true, and that the expression:x.clone() != x
will bex.clone().getClass() == x.getClass()
true
, but these are not absolute requirements. While it is typically the case that:
will bex.clone().equals(x)
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.

void draw (Canvas canvas, Paint paint)
Draw this shape into the provided Canvas, with the provided Paint. Before calling this, you must call resize(float, float)
.
Parameters | |
---|---|
canvas |
Canvas : the Canvas within which this shape should be drawn |
paint |
Paint : the Paint object that defines this shape's characteristics |
void onResize (float width, float height)
Callback method called when resize(float, float)
is executed.
Parameters | |
---|---|
width |
float : the new width of the Shape |
height |
float : the new height of the Shape |
