public final class ZoomGestureDetector.ZoomEvent.Move extends ZoomGestureDetector.ZoomEvent

java.lang.Object
↳	androidx.camera.viewfinder.core.ZoomGestureDetector.ZoomEvent
	↳	androidx.camera.viewfinder.core.ZoomGestureDetector.ZoomEvent.Move

The moving events of a gesture in progress. Reported by pointer motion.

Summary

Public constructors
`Move( @IntRange(from = 0) long eventTime, @Px @IntRange(from = 0) int focusX, @Px @IntRange(from = 0) int focusY, @FloatRange(from = 0.0, fromInclusive = false) float scaleFactor )`

Public methods
`final float`	`getScaleFactor()` The scaling factor from the previous zoom event to the current event.

Inherited methods

From androidx.camera.viewfinder.core.ZoomGestureDetector.ZoomEvent

`final long`	`getEventTime()` The event time in milliseconds of the current event being processed, in `SystemClock.uptimeMillis` time base.
`final int`	`getFocusX()` The X coordinate of the current gesture's focal point in pixels.
`final int`	`getFocusY()` The Y coordinate of the current gesture's focal point in pixels.

Public constructors

Move

Added in 1.4.0-alpha06

public Move(
    @IntRange(from = 0) long eventTime,
    @Px @IntRange(from = 0) int focusX,
    @Px @IntRange(from = 0) int focusY,
    @FloatRange(from = 0.0, fromInclusive = false) float scaleFactor
)

Parameters
`@IntRange(from = 0) long eventTime`	The event time in milliseconds of the current event being processed, in `SystemClock.uptimeMillis` time base.
`@Px @IntRange(from = 0) int focusX`	The X coordinate of the current gesture's focal point in pixels.
`@Px @IntRange(from = 0) int focusY`	The Y coordinate of the current gesture's focal point in pixels.
`@FloatRange(from = 0.0, fromInclusive = false) float scaleFactor`	The scaling factor from the previous zoom event to the current event. The value will be less than `1.0` when zooming out (larger FOV) and will be larger than `1.0` when zooming in (narrower FOV).

Public methods

getScaleFactor

Added in 1.4.0-alpha06

public final float getScaleFactor()

The scaling factor from the previous zoom event to the current event. The value will be less than 1.0 when zooming out (larger FOV) and will be larger than 1.0 when zooming in (narrower FOV).
