InputDevice.MotionRange

public static final class InputDevice.MotionRange
extends Object

java.lang.Object
   ↳ android.view.InputDevice.MotionRange


Provides information about the range of values for a particular MotionEvent axis.

Summary

Public methods

int getAxis()

Gets the axis id.

float getFlat()

Gets the extent of the center flat position with respect to this axis.

float getFuzz()

Gets the error tolerance for input device measurements with respect to this axis.

float getMax()

Gets the inclusive maximum value for the axis.

float getMin()

Gets the inclusive minimum value for the axis.

float getRange()

Gets the range of the axis (difference between maximum and minimum).

float getResolution()

Gets the resolution for input device measurements with respect to this axis.

int getSource()

Gets the source for which the axis is defined.

boolean isFromSource(int source)

Determines whether the event is from the given source.

Inherited methods

Public methods

getAxis

added in API level 12
public int getAxis ()

Gets the axis id.

Returns
int The axis id.

getFlat

added in API level 9
public float getFlat ()

Gets the extent of the center flat position with respect to this axis.

For example, a flat value of 8 means that the center position is between -8 and +8. This value is mainly useful for calibrating self-centering devices.

Returns
float The extent of the center flat position.

getFuzz

added in API level 9
public float getFuzz ()

Gets the error tolerance for input device measurements with respect to this axis.

For example, a value of 2 indicates that the measured value may be up to +/- 2 units away from the actual value due to noise and device sensitivity limitations.

Returns
float The error tolerance.

getMax

added in API level 9
public float getMax ()

Gets the inclusive maximum value for the axis.

Returns
float The inclusive maximum value.

getMin

added in API level 9
public float getMin ()

Gets the inclusive minimum value for the axis.

Returns
float The inclusive minimum value.

getRange

added in API level 9
public float getRange ()

Gets the range of the axis (difference between maximum and minimum).

Returns
float The range of values.

getResolution

added in API level 18
public float getResolution ()

Gets the resolution for input device measurements with respect to this axis.

Returns
float The resolution in units per millimeter, or units per radian for rotational axes.

getSource

added in API level 12
public int getSource ()

Gets the source for which the axis is defined.

Returns
int The source.

isFromSource

added in API level 18
public boolean isFromSource (int source)

Determines whether the event is from the given source.

Parameters
source int: The input source to check against. This can be a specific device type, such as InputDevice.SOURCE_TOUCH_NAVIGATION, or a more generic device class, such as InputDevice.SOURCE_CLASS_POINTER.

Returns
boolean Whether the event is from the given source.
