    float progress
)

Called when a drawer's position changes.

Parameters
`MotionLayout motionLayout`	The TransitionLayout view that was moved
`int startId`	the id of the start state (or ConstraintSet). Will be -1 if unknown.
`int endId`	the id of the end state (or ConstraintSet).
`float progress`	The progress on this transition, from 0 to 1.

Added in 2.2.0

public void onTransitionCompleted(MotionLayout motionLayout, int currentId)

Called when a drawer has settled completely a state. The TransitionLayout is interactive at this point.

Parameters
`MotionLayout motionLayout`	Drawer view that is now open
`int currentId`	the id it has reached

Added in 2.2.0

public void onTransitionStarted(MotionLayout motionLayout, int startId, int endId)

Called when a drawer is about to start a transition. Note. startId may be -1 if starting from an "undefined state"

Parameters
`MotionLayout motionLayout`	The TransitionLayout view that was moved
`int startId`	the id of the start state (or ConstraintSet). Will be -1 if unknown.
`int endId`	the id of the end state (or ConstraintSet).

Added in 2.2.0

public void onTransitionTrigger(
    MotionLayout motionLayout,
    int triggerId,
    boolean positive,
    float progress
)

Call when a trigger is fired

Parameters
`MotionLayout motionLayout`
`int triggerId`	The id set set with triggerID
`boolean positive`	for positive transition edge
`float progress`
