public RoundRectShape(float[] outerRadii, RectF inset, float[] innerRadii)
outerRadii
- An array of 8 radius values, for the outer roundrect.
The first two floats are for the
top-left corner (remaining pairs correspond clockwise).
For no rounded corners on the outer rectangle,
pass null.inset
- A RectF that specifies the distance from the inner
rect to each side of the outer rect.
For no inner, pass null.innerRadii
- An array of 8 radius values, for the inner roundrect.
The first two floats are for the
top-left corner (remaining pairs correspond clockwise).
For no rounded corners on the inner rectangle,
pass null.
If inset parameter is null, this parameter is ignored.public void draw(Canvas canvas, Paint paint)

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.

- if the object's class does not
support the Cloneable
interface. Subclasses
that override the clone
method can also
throw this exception to indicate that an instance cannot
be cloned.Cloneable
