public final 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.

Summary

Fields

public Sensor sensor

The sensor that generated this event.

public long timestamp

The time in nanosecond at which the event happened

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).

Inherited methods

From class java.lang.Object

Object clone()

Creates and returns a copy of this object.

boolean equals(Object obj)

Indicates whether some other object is "equal to" this one.

void finalize()

Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.

final Class<?> getClass()

Returns the runtime class of this Object.

int hashCode()

Returns a hash code value for the object.

final void notify()

Wakes up a single thread that is waiting on this object's monitor.

final void notifyAll()

Wakes up all threads that are waiting on this object's monitor.

String toString()

Returns a string representation of the object.

final void wait(long timeoutMillis, int nanos)

Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.

final void wait(long timeoutMillis)

Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.

final void wait()

Causes the current thread to wait until it is awakened, typically by being notified or interrupted.

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).

Sensor#TYPE_SIGNIFICANT_MOTION

The value field is of length 1. value[0] = 1.0 when the sensor triggers. 1.0 is the only allowed value.
