getMax()
Gets the inclusive maximum value for the axis.
|
float |
getMin()
Gets the inclusive minimum value for the axis.
|

source
- 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
.public float getMin()
public float getMax()
public float getRange()
public float getFlat()
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.
public float getFuzz()
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.
