MotionScene

MotionScene(layout: MotionLayout!)

Create a motion scene.

fun addOnClickListeners(motionLayout: MotionLayout!, currentState: Int): Unit

Add all on click listeners for the current state

fun addTransition(transition: MotionScene.Transition!): Unit

Add a transition to the motion scene. If a transition with the same id already exists in the scene, the new transition will replace the existing one.

fun applyViewTransition(
    viewTransitionId: Int,
    motionController: MotionController!
): Boolean

Apply a view transition to the MotionController

fun bestTransitionFor(
    currentState: Int,
    dx: Float,
    dy: Float,
    lastTouchDown: MotionEvent!
): MotionScene.Transition!

Find the best transition for the motion

fun disableAutoTransition(disable: Boolean): Unit

this allow disabling autoTransitions to prevent design surface from being in undefined states

fun enableViewTransition(id: Int, enable: Boolean): Unit

Enable this viewTransition

fun gatPathMotionArc(): Int

The transition arc path mode

fun getConstraintSet(context: Context!, id: String!): ConstraintSet!

Get the constraintSet given the id

fun getConstraintSetIds(): IntArray<Int>!

Get the list of all Constraint Sets Know to the system

fun getDefinedTransitions(): ArrayList<MotionScene.Transition!>!

Get list of Transitions know to the system

fun getDuration(): Int

Get Duration of the current transition.

fun getInterpolator(): Interpolator!

Get the interpolator define for the current Transition

fun getKeyFrames(motionController: MotionController!): Unit

provides the key frames &CycleFrames to the motion view to

fun getMatchingStateLabels(types: Array<String!>!): IntArray<Int>!

Get the id's of all constraintSets with the matching types

fun getPathPercent(view: View!, position: Int): Float

Get the path percent (Non functional currently)

fun getStaggered(): Float

Get the staggered value of the current transition. Will default to 0 staggered if there is no current transition.

fun getTransitionById(id: Int): MotionScene.Transition!

Find the transition based on the id

fun getTransitionsWithState(stateId: Int): (Mutable)List<MotionScene.Transition!>!

Get all transitions that include this state

Is this view transition enabled

fun lookUpConstraintId(id: String!): Int

Used at design time

fun lookUpConstraintName(id: Int): String!

used at design time

fun removeTransition(transition: MotionScene.Transition!): Unit

Remove the transition with the matching id from the motion scene. If no matching transition is found, it does nothing.

fun setConstraintSet(id: Int, set: ConstraintSet!): Unit

Maps the Constraint set to the id.

fun setDuration(duration: Int): Unit

Sets the duration of the current transition or the default if there is no current transition

Set a keyFrame on the current Transition

fun setRtl(rtl: Boolean): Unit

Set Right to left

fun setTransition(transition: MotionScene.Transition!): Unit

Set the transition to be the current transition of the motion scene.

java-static fun stripID(id: String!): String!

Utility to strip the @id/ from an id

fun viewTransition(id: Int, view: Array<View!>!): Unit

Apply the viewTransition on the list of views
