TriggerEvent

public final class TriggerEvent
extends Object

java.lang.Object
   ↳ android.hardware.TriggerEvent


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 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.
