• Field Detail

  • x

    public float x

    The X component of the pointer movement.

    See Also:

    MotionEvent.AXIS_X

  • y

    public float y

    The Y component of the pointer movement.

    See Also:

    MotionEvent.AXIS_Y

  • pressure

    public float pressure

    A normalized value that describes the pressure applied to the device by a finger or other tool. The pressure generally ranges from 0 (no pressure at all) to 1 (normal pressure), although values higher than 1 may be generated depending on the calibration of the input device.

    See Also:

    MotionEvent.AXIS_PRESSURE

  • size

    public float size

    A normalized value that describes the approximate size of the pointer touch area in relation to the maximum detectable size of the device. It represents some approximation of the area of the screen being pressed; the actual value in pixels corresponding to the touch is normalized with the device specific range of values and scaled to a value between 0 and 1. The value of size can be used to determine fat touch events.

    See Also:

    MotionEvent.AXIS_SIZE

  • touchMajor

    public float touchMajor

    The length of the major axis of an ellipse that describes the touch area at the point of contact. If the device is a touch screen, the length is reported in pixels, otherwise it is reported in device-specific units.

    See Also:

    MotionEvent.AXIS_TOUCH_MAJOR

  • touchMinor

    public float touchMinor

    The length of the minor axis of an ellipse that describes the touch area at the point of contact. If the device is a touch screen, the length is reported in pixels, otherwise it is reported in device-specific units.

    See Also:

    MotionEvent.AXIS_TOUCH_MINOR

  • toolMajor

    public float toolMajor

    The length of the major axis of an ellipse that describes the size of the approaching tool. The tool area represents the estimated size of the finger or pen that is touching the device independent of its actual touch area at the point of contact. If the device is a touch screen, the length is reported in pixels, otherwise it is reported in device-specific units.

    See Also:

    MotionEvent.AXIS_TOOL_MAJOR

  • toolMinor

    public float toolMinor

    The length of the minor axis of an ellipse that describes the size of the approaching tool. The tool area represents the estimated size of the finger or pen that is touching the device independent of its actual touch area at the point of contact. If the device is a touch screen, the length is reported in pixels, otherwise it is reported in device-specific units.

    See Also:

    MotionEvent.AXIS_TOOL_MINOR

  • orientation

    public float orientation

    The orientation of the touch area and tool area in radians clockwise from vertical. An angle of 0 radians indicates that the major axis of contact is oriented upwards, is perfectly circular or is of unknown orientation. A positive angle indicates that the major axis of contact is oriented to the right. A negative angle indicates that the major axis of contact is oriented to the left. The full range is from -PI/2 radians (finger pointing fully left) to PI/2 radians (finger pointing fully right).
