class
TriggerEvent
extends Object
This class represents a Trigger Event - the event
associated with a Trigger Sensor. When the sensor detects a trigger
event condition, such as significant motion in the case of the
Sensor.TYPE_SIGNIFICANT_MOTION, the TriggerEventListener
is called with the TriggerEvent. The sensor is automatically canceled
after the trigger.
This class holds information such as the value of the sensor
when the trigger happened, the timestamp along with detailed
information regarding the Sensor itself.

Fields
sensor
public Sensor sensor
The sensor that generated this event. See
SensorManager for details.
timestamp
public long timestamp
The time in nanosecond at which the event happened
values
public final float[] values
The length and contents of the values array depends on
which sensor type is being monitored (see
also SensorEvent for a definition of the coordinate system used).
The value field is of length 1. value[0] = 1.0 when the sensor triggers.
1.0 is the only allowed value.
