Inherited methods

From class java.lang.Object Object clone() Creates and returns a copy of this object. boolean equals(Object obj) Indicates whether some other object is "equal to" this one. void finalize() Called by the garbage collector on an object when garbage collection determines that there are no more references to the object. final Class<?> getClass() Returns the runtime class of this Object. int hashCode() Returns a hash code value for the object. final void notify() Wakes up a single thread that is waiting on this object's monitor. final void notifyAll() Wakes up all threads that are waiting on this object's monitor. String toString() Returns a string representation of the object. final void wait(long timeoutMillis, int nanos) Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed. final void wait(long timeoutMillis) Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed. final void wait() Causes the current thread to wait until it is awakened, typically by being notified or interrupted.

This constructor is deprecated.
Use get(android.content.Context) instead.

Public methods

get

Added in API level 3

public static ViewConfiguration get (Context context)

Returns a configuration for the specified visual Context. The configuration depends on various parameters of the Context, like the dimension of the display or the density of the display.

Parameters

Parameters
inputDeviceId	int

Returns

getScaledMaximumFlingVelocity

Added in API level 4

public int getScaledMaximumFlingVelocity ()

Returns
int	Maximum velocity to initiate a fling, as measured in pixels per second.

getScaledMinimumFlingVelocity

Added in API level 34

public int getScaledMinimumFlingVelocity (int inputDeviceId, 
                int axis, 
                int source)

Minimum absolute value of velocity to initiate a fling for a motion generated by an InputDevice with an id of inputDeviceId, from an input source and on a given motion event axis.

Before utilizing this method to get a minimum fling velocity for a motion generated by the input device, scale the velocity of the motion events generated by the input device to pixels per second.

For instance, if you tracked MotionEvent.AXIS_SCROLL vertical velocities generated from a InputDevice.SOURCE_ROTARY_ENCODER, the velocity returned from VelocityTracker will be in the units with which the axis values were reported in the motion event. Before comparing that velocity against the minimum fling velocity specified here, make sure that the MotionEvent.AXIS_SCROLL velocity from the tracker is calculated in "units per second" (see VelocityTracker.computeCurrentVelocity(int), VelocityTracker.computeCurrentVelocity(int, float) to adjust your velocity computations to "per second"), and use getScaledVerticalScrollFactor() to change this velocity value to "pixels/second".

If the provided inputDeviceId is not valid, or if the input device whose ID is provided does not support the given motion event source and/or axis, this method will return Integer.MAX_VALUE.

Obtaining the correct arguments for this method call

inputDeviceId: if calling this method in response to a MotionEvent, use the device ID that is reported by the event, which can be obtained using MotionEvent.getDeviceId(). Otherwise, use a valid ID that is obtained from InputDevice.getId(), or from an InputManager instance (InputManager.getInputDeviceIds() gives all the valid input device IDs).

axis: a MotionEvent may report data for multiple axes, and each axis may have multiple data points for different pointers. Use the axis for which you obtained the velocity for (VelocityTracker lets you calculate velocities for a specific axis. Use the axis for which you calculated velocity). You can use InputDevice.getMotionRanges() to get all the InputDevice.MotionRanges for the InputDevice, from which you can derive all the valid axes for the device.

source: use MotionEvent.getSource() if calling this method in response to a MotionEvent. Otherwise, use a valid source for the InputDevice. You can use InputDevice.getMotionRanges() to get all the InputDevice.MotionRanges for the InputDevice, from which you can derive all the valid sources for the device.

This method optimizes calls over multiple input device IDs, so caching the return value of the method is not necessary if you are handling multiple input devices.

Parameters
inputDeviceId	int: the ID of the InputDevice that generated the motion triggering fling.
axis	int: the axis on which the motion triggering the fling happened. This axis should be a valid axis that can be reported by the provided input device from the provided input device source.
source	int: the input source of the motion causing fling. This source should be a valid source for the InputDevice whose ID is inputDeviceId.

Returns
int	the minimum velocity, in pixels/second, to trigger fling.

Added in API level 29

public int getScaledMinimumScalingSpan ()
