Public constructors
TransitionAdapter
public TransitionAdapter ()
Public methods
onTransitionChange
public void onTransitionChange (MotionLayout motionLayout,
int startId,
int endId,
float progress)
Called when a drawer's position changes.
| Parameters |
|---|
motionLayout |
MotionLayout: The TransitionLayout view that was moved |
startId |
int: the id of the start state (or ConstraintSet). Will be -1 if unknown. |
endId |
int: the id of the end state (or ConstraintSet). |
progress |
float: The progress on this transition, from 0 to 1.
|
onTransitionCompleted
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 |
currentId |
int: the id it has reached
|
onTransitionStarted
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 |
startId |
int: the id of the start state (or ConstraintSet). Will be -1 if unknown. |
endId |
int: the id of the end state (or ConstraintSet).
|
onTransitionTrigger
public void onTransitionTrigger (MotionLayout motionLayout,
int triggerId,
boolean positive,
float progress)
Call when a trigger is fired
| Parameters |
|---|
triggerId |
int: The id set set with triggerID |
positive |
boolean: for positive transition edge |
