GestureDescription.StrokeDescription

added in API level 24
public GestureDescription.StrokeDescription (Path path, 
                long startTime, 
                long duration)

Parameters
path Path: The path to follow. Must have exactly one contour. The bounds of the path must not be negative. The path must not be empty. If the path has zero length (for example, a single moveTo()), the stroke is a touch that doesn't move.

This value must never be null.

startTime long: The time, in milliseconds, from the time the gesture starts to the time the stroke should start. Must not be negative.

duration long: The duration, in milliseconds, the stroke takes to traverse the path. Must be positive.

GestureDescription.StrokeDescription

added in API level 26
public GestureDescription.StrokeDescription (Path path, 
                long startTime, 
                long duration, 
                boolean willContinue)

Parameters
path Path: The path to follow. Must have exactly one contour. The bounds of the path must not be negative. The path must not be empty. If the path has zero length (for example, a single moveTo()), the stroke is a touch that doesn't move.

This value must never be null.

startTime long: The time, in milliseconds, from the time the gesture starts to the time the stroke should start. Must not be negative.

duration long: The duration, in milliseconds, the stroke takes to traverse the path. Must be positive.

willContinue boolean: true if this stroke will be continued by one in the next gesture false otherwise. Continued strokes keep their pointers down when the gesture completes.

Public methods

continueStroke

added in API level 26
public GestureDescription.StrokeDescription continueStroke (Path path, 
                long startTime, 
                long duration, 
                boolean willContinue)

Create a new stroke that will continue this one. This is only possible if this stroke will continue.

Parameters
path Path: The path for the stroke that continues this one. The starting point of this path must match the ending point of the stroke it continues.

startTime long: The time, in milliseconds, from the time the gesture starts to the time this stroke should start. Must not be negative. This time is from the start of the new gesture, not the one being continued.

duration long: The duration for the new stroke. Must not be negative.

willContinue boolean: true if this stroke will be continued by one in the next gesture false otherwise.
