public interface SensorListener {
Called when sensor values have changed. The length and contents of the values array vary depending on which sensor is being monitored. See SensorManager for details on possible sensor types.
Definition of the coordinate system used below.
The X axis refers to the screen's horizontal axis
(the small edge in portrait mode, the long edge in landscape mode) and
points to the right.
The Y axis refers to the screen's vertical axis and points towards
the top of the screen (the origin is in the lower-left corner).
The Z axis points toward the sky when the device is lying on its back
on a table.
IMPORTANT NOTE: The axis are swapped when the
device's screen orientation changes. To access the unswapped values,
use indices 3, 4 and 5 in values[].
SENSOR_ORIENTATION, SENSOR_ORIENTATION_RAW:
All values are angles in degrees.
values[0]: Azimuth, rotation around the Z axis (0<=azimuth<360).
0 = North, 90 = East, 180 = South, 270 = West
values[1]: Pitch, rotation around X axis (-180<=pitch<=180), with positive
values when the z-axis moves toward the y-axis.
values[2]: Roll, rotation around Y axis (-90<=roll<=90), with positive values
when the z-axis moves toward the x-axis.
Note that this definition of yaw, pitch and roll is different from the
traditional definition used in aviation where the X axis is along the long
side of the plane (tail to nose).
All values are in SI units (m/s^2) and measure contact forces.
values[0]: force applied by the device on the x-axis
values[1]: force applied by the device on the y-axis
values[2]: force applied by the device on the z-axis
Examples:
When the device is pushed on its left side toward the right, the
x acceleration value is negative (the device applies a reaction force
to the push toward the left)
When the device lies flat on a table, the acceleration value is -STANDARD_GRAVITY, which correspond to the force the device applies on the table in reaction to gravity.
All values are in micro-Tesla (uT) and measure the ambient magnetic
field in the X, Y and -Z axis.
Note: the magnetic field's Z axis is inverted.
Params: - sensor – The ID of the sensor being monitored
- values – The new values for the sensor.
