StateListAnimator
extends Object
implements
Cloneable
java.lang.Object | |
↳ | android.animation.StateListAnimator |
Lets you define a number of Animators that will run on the attached View depending on the View's drawable state.
It can be defined in an XML file with the <selector>
element.
Each State Animator is defined in a nested <item>
element.

---|---|
Animation to use on each child.
May be a reference to another resource, in the form
"@[+][package:]type/name
" or a theme
attribute in the form
"?[package:]type/name
".
State value for StateListDrawable
,
set when a view or its parent has been "activated" meaning the user has currently
marked it as being of interest. This is an alternative representation of
state_checked for when the state should be propagated down the view hierarchy.
May be a boolean value, such as "true
" or
"false
".
State value for StateListDrawable
,
set when a view or drawable is considered "active" by its host. Actual usage may vary
between views. Consult the host view documentation for details.
May be a boolean value, such as "true
" or
"false
".
State identifier indicating that the object may display a check mark. See
R.attr.state_checked
for the identifier that indicates whether it is
actually checked.
May be a boolean value, such as "true
" or
"false
".
State identifier indicating that the object is currently checked. See
R.attr.state_checkable
for an additional identifier that can indicate
if any object may ever display a check, regardless of whether state_checked is
currently set.
May be a boolean value, such as "true
" or
"false
".
State value for StateListDrawable
,
set when a view is enabled.
May be a boolean value, such as "true
" or
"false
".
State value for StateListDrawable

set when a view or drawable is in the first position in an ordered set. Actual usage
may vary between views. Consult the host view documentation for details.

public StateListAnimator ()
public void addState (int[] specs, Animator animator)
Associates the given animator with the provided drawable state specs so that it will be run when the View's drawable state matches the specs.
Parameters | |
---|---|
specs |
int : The drawable state specs to match against |
animator |
Animator : The animator to run when the specs match |
public StateListAnimator 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.

a clone of this instance. |
public void jumpToCurrentState ()
If there is an animation running for a recent state change, ends it.
This causes the animation to assign the end value(s) to the View.
