Method Detail

onValueChanged

public void onValueChanged()

Specified by:

onValueChanged in interface BaseKeyframeAnimation.AnimationListener

addAnimation

public void addAnimation(@Nullable
                         BaseKeyframeAnimation<?,?> newAnimation)

removeAnimation

public void removeAnimation(BaseKeyframeAnimation<?,?> animation)

getBounds

@CallSuper
public void getBounds(RectF outBounds,
                      Matrix parentMatrix,
                      boolean applyParents)

Specified by:

getBounds in interface DrawingContent

draw

public void draw(Canvas canvas,
                 Matrix parentMatrix,
                 int parentAlpha)

Specified by:

draw in interface DrawingContent

getName

public java.lang.String getName()

Specified by:

getName in interface Content

setContents

public void setContents(java.util.List<Content> contentsBefore,
                        java.util.List<Content> contentsAfter)

Specified by:

setContents in interface Content

resolveKeyPath

public void resolveKeyPath(KeyPath keyPath,
                           int depth,
                           java.util.List<KeyPath> accumulator,
                           KeyPath currentPartialKeyPath)

Description copied from interface: KeyPathElement

Called recursively during keypath resolution. The overridden method should just call: MiscUtils.resolveKeyPath(keyPath, depth, accumulator, currentPartialKeyPath, this);

Specified by:

resolveKeyPath in interface KeyPathElement

Parameters:

keyPath - The full keypath being resolved.

depth - The current depth that this element should be checked at in the keypath.

accumulator - A list of fully resolved keypaths. If this element fully matches the keypath then it should add itself to this list.

currentPartialKeyPath - A keypath that contains all parent element of this one. This element should create a copy of this and append itself with KeyPath#addKey when it adds itself to the accumulator or propagates resolution to its children.

addValueCallback

@CallSuper
public <T> void addValueCallback(T property,
                                 @Nullable
                                 LottieValueCallback<T> callback)

Description copied from interface: KeyPathElement

The overridden method should handle appropriate properties and set value callbacks on their animations.

Specified by:

addValueCallback in interface KeyPathElement
