Public methods

getShapeProvider

MaterialContainerTransformSharedElementCallback.ShapeProvider getShapeProvider ()

Get the MaterialContainerTransformSharedElementCallback.ShapeProvider for this callback, or null if it is not set.

Returns
MaterialContainerTransformSharedElementCallback.ShapeProvider

isSharedElementReenterTransitionEnabled

boolean isSharedElementReenterTransitionEnabled ()

Returns whether incoming Activity's sharedElementReenterTransition will be respected.

Returns
boolean

• setSharedElementReenterTransitionEnabled(boolean)

isTransparentWindowBackgroundEnabled

boolean isTransparentWindowBackgroundEnabled ()

Returns whether the incoming window's background should be made transparent during the transition.

Returns
boolean

See also:

• setTransparentWindowBackgroundEnabled(boolean)

onCaptureSharedElementSnapshot

Parcelable onCaptureSharedElementSnapshot (View sharedElement, 
                Matrix viewToGlobalMatrix, 
                RectF screenBounds)

Parameters
sharedElement	View
viewToGlobalMatrix	Matrix
screenBounds	RectF

Returns
Parcelable

onCreateSnapshotView

View onCreateSnapshotView (Context context, 
                Parcelable snapshot)

Parameters
context	Context
snapshot	Parcelable

Returns
View

onMapSharedElements

void onMapSharedElements (List<String> names, 
                Map<String, View> sharedElements)

Parameters
names	List
sharedElements	Map

onSharedElementEnd

void onSharedElementEnd (List<String> sharedElementNames, 
                List<View> sharedElements, 
                List<View> sharedElementSnapshots)

Parameters
sharedElementNames	List
sharedElements	List
sharedElementSnapshots	List

onSharedElementStart

void onSharedElementStart (List<String> sharedElementNames, 
                List<View> sharedElements, 
                List<View> sharedElementSnapshots)

Parameters
sharedElementNames	List
sharedElements	List
sharedElementSnapshots	List

setShapeProvider

void setShapeProvider (MaterialContainerTransformSharedElementCallback.ShapeProvider shapeProvider)

Set the MaterialContainerTransformSharedElementCallback.ShapeProvider for this callback, which allows providing a ShapeAppearanceModel for the shared element view.

The default is a MaterialContainerTransformSharedElementCallback.ShapeableViewShapeProvider, which will use the view's ShapeAppearanceModel if the view implements the Shapeable interface.

Parameters
shapeProvider	MaterialContainerTransformSharedElementCallback.ShapeProvider

setSharedElementReenterTransitionEnabled

void setSharedElementReenterTransitionEnabled (boolean sharedElementReenterTransitionEnabled)

If enabled, the Activity's sharedElementReenterTransition will be respected; otherwise it will be set to null. Default is false, meaning the sharedElementReenterTransition will be set to null.

Parameters
sharedElementReenterTransitionEnabled	boolean

setTransparentWindowBackgroundEnabled

void setTransparentWindowBackgroundEnabled (boolean transparentWindowBackgroundEnabled)

If enabled, the incoming window's background will be made transparent during the transition. This results in an effect where the outgoing activity's content is visible for the duration of the transition, because the incoming window background will not be faded in on top of it. Default is true.

Note: in order to avoid some visual artifacts, when this setting is enabled the window's transition background fade duration (see setTransitionBackgroundFadeDuration(long)) will be overridden to be greater than the duration of the transform transition.

Parameters
transparentWindowBackgroundEnabled	boolean
