VelocityTracker.ComputeCurrentVelocity Method

Definition

Namespace:

Android.Views

Assembly:

Mono.Android.dll

Overloads

ComputeCurrentVelocity(Int32)	Equivalent to invoking #computeCurrentVelocity(int, float) with a maximum velocity of Float.
ComputeCurrentVelocity(Int32, Single)	Compute the current velocity based on the points that have been collected.

ComputeCurrentVelocity(Int32)

Equivalent to invoking #computeCurrentVelocity(int, float) with a maximum velocity of Float.

[Android.Runtime.Register("computeCurrentVelocity", "(I)V", "")]
public void ComputeCurrentVelocity (int units);

[<Android.Runtime.Register("computeCurrentVelocity", "(I)V", "")>]
member this.ComputeCurrentVelocity : int -> unit

Parameters

units

Int32

Attributes

RegisterAttribute

Remarks

Equivalent to invoking #computeCurrentVelocity(int, float) with a maximum velocity of Float.MAX_VALUE.

ComputeCurrentVelocity(Int32, Single)

Compute the current velocity based on the points that have been collected.

[Android.Runtime.Register("computeCurrentVelocity", "(IF)V", "")]
public void ComputeCurrentVelocity (int units, float maxVelocity);

[<Android.Runtime.Register("computeCurrentVelocity", "(IF)V", "")>]
member this.ComputeCurrentVelocity : int * single -> unit

Parameters

units

Int32

The units you would like the velocity in. A value of 1 provides units per millisecond, 1000 provides units per second, etc. Note that the units referred to here are the same units with which motion is reported. For axes X and Y, the units are pixels.

maxVelocity

Single

The maximum velocity that can be computed by this method. This value must be declared in the same unit as the units parameter. This value must be positive.

Attributes

RegisterAttribute

Remarks

Compute the current velocity based on the points that have been collected. Only call this when you actually want to retrieve velocity information, as it is relatively expensive. You can then retrieve the velocity with #getXVelocity() and #getYVelocity().
