MotionRange

Kotlin |Java

class MotionRange

kotlin.Any
↳	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(source: Int)` Determines whether the event is from the given source.

Public methods

getAxis

Added in API level 12

fun getAxis(): Int

Gets the axis id.

Return
`Int`	The axis id.

getFlat

Added in API level 9

fun getFlat(): Float

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.

Return
`Float`	The extent of the center flat position.

getFuzz

Added in API level 9

fun getFuzz(): Float

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.

Return
`Float`	The error tolerance.

getMax

Added in API level 9

fun getMax(): Float

Gets the inclusive maximum value for the axis.

Return
`Float`	The inclusive maximum value.

getMin

Added in API level 9

fun getMin(): Float

Gets the inclusive minimum value for the axis.

Return
`Float`	The inclusive minimum value.

getRange

Added in API level 9

fun getRange(): Float

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

Return
`Float`	The range of values.

getResolution

Added in API level 18

fun getResolution(): Float

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

Return
`Float`	The resolution in units per millimeter, or units per radian for rotational axes.

getSource

Added in API level 12

fun getSource(): Int

Gets the source for which the axis is defined.

Return
`Int`	The source.

isFromSource

Added in API level 18

fun isFromSource(source: Int): Boolean

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`.

Return
`Boolean`	Whether the event is from the given source.
