| Methods Summary |
|---|
| 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.
Tuple tuple = new Tuple(specs, animator);
tuple.mAnimator.addListener(mAnimatorListener);
mTuples.add(tuple);
mChangingConfigurations |= animator.getChangingConfigurations();
|
| public void | appendChangingConfigurations(int configs)Sets the changing configurations value to the union of the current changing configurations
and the provided configs.
This method is called while loading the animator.
mChangingConfigurations |= configs;
|
| private void | cancel()
if (mRunningAnimator != null) {
mRunningAnimator.cancel();
mRunningAnimator = null;
}
|
| private void | clearTarget()
final int size = mTuples.size();
for (int i = 0; i < size; i++) {
mTuples.get(i).mAnimator.setTarget(null);
}
mViewRef = null;
mLastMatch = null;
mRunningAnimator = null;
|
| public android.animation.StateListAnimator | clone()
try {
StateListAnimator clone = (StateListAnimator) super.clone();
clone.mTuples = new ArrayList<Tuple>(mTuples.size());
clone.mLastMatch = null;
clone.mRunningAnimator = null;
clone.mViewRef = null;
clone.mAnimatorListener = null;
clone.initAnimatorListener();
final int tupleSize = mTuples.size();
for (int i = 0; i < tupleSize; i++) {
final Tuple tuple = mTuples.get(i);
final Animator animatorClone = tuple.mAnimator.clone();
animatorClone.removeListener(mAnimatorListener);
clone.addState(tuple.mSpecs, animatorClone);
}
clone.setChangingConfigurations(getChangingConfigurations());
return clone;
} catch (CloneNotSupportedException e) {
throw new AssertionError("cannot clone state list animator", e);
}
|
| public android.content.res.ConstantState | createConstantState()Return a {@link android.content.res.ConstantState} instance that holds the shared state of
this Animator.
This constant state is used to create new instances of this animator when needed. Default
implementation creates a new {@link StateListAnimatorConstantState}. You can override this
method to provide your custom logic or return null if you don't want this animator to be
cached.
return new StateListAnimatorConstantState(this);
|
| public int | getChangingConfigurations()Return a mask of the configuration parameters for which this animator may change, requiring
that it be re-created. The default implementation returns whatever was provided through
{@link #setChangingConfigurations(int)} or 0 by default.
return mChangingConfigurations;
|
| public Animator | getRunningAnimator()Returns the current {@link android.animation.Animator} which is started because of a state
change.
return mRunningAnimator;
|
| public android.view.View | getTarget()
return mViewRef == null ? null : mViewRef.get();
|
| public java.util.ArrayList | getTuples()
return mTuples;
|
| private void | initAnimatorListener()
mAnimatorListener = new AnimatorListenerAdapter() {
@Override
public void onAnimationEnd(Animator animation) {
animation.setTarget(null);
if (mRunningAnimator == animation) {
mRunningAnimator = null;
}
}
};
|
| 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.
if (mRunningAnimator != null) {
mRunningAnimator.end();
}
|
| public void | setChangingConfigurations(int configs)Set a mask of the configuration parameters for which this animator may change, requiring
that it should be recreated from resources instead of being cloned.
mChangingConfigurations = configs;
|
| public void | setState(int[] state)Called by View
Tuple match = null;
final int count = mTuples.size();
for (int i = 0; i < count; i++) {
final Tuple tuple = mTuples.get(i);
if (StateSet.stateSetMatches(tuple.mSpecs, state)) {
match = tuple;
break;
}
}
if (match == mLastMatch) {
return;
}
if (mLastMatch != null) {
cancel();
}
mLastMatch = match;
if (match != null) {
start(match);
}
|
| public void | setTarget(android.view.View view)Called by View
final View current = getTarget();
if (current == view) {
return;
}
if (current != null) {
clearTarget();
}
if (view != null) {
mViewRef = new WeakReference<View>(view);
}
|
| private void | start(android.animation.StateListAnimator$Tuple match)
match.mAnimator.setTarget(getTarget());
mRunningAnimator = match.mAnimator;
mRunningAnimator.start();
