TriggerEventListener

public abstract class TriggerEventListener
extends Object

This class is the listener used to handle Trigger Sensors. Trigger Sensors are sensors that trigger an event and are automatically disabled. TYPE_SIGNIFICANT_MOTION is one such example.

SensorManager lets you access the device's sensors. Get an instance of SensorManager by calling Context.getSystemService() with the argument SENSOR_SERVICE.

Here's an example setup for a TriggerEventListener:

 class TriggerListener extends TriggerEventListener {
     public void onTrigger(TriggerEvent event) {
          // Do Work.

     // As it is a one shot sensor, it will be canceled automatically.
     // SensorManager.requestTriggerSensor(this, mSigMotion); needs to
     // be called again, if needed.
     }
 }
 public class SensorActivity extends Activity {
     private final SensorManager mSensorManager;
     private final Sensor mSigMotion;
     private final TriggerEventListener mListener = new TriggerEventListener();

     public SensorActivity() {
         mSensorManager = (SensorManager)getSystemService(SENSOR_SERVICE);
         mSigMotion = mSensorManager.getDefaultSensor(Sensor.TYPE_SIGNIFICANT_MOTION);
     }

     protected void onResume() {
         super.onResume();
         mSensorManager.requestTriggerSensor(mListener, mSigMotion);
     }

     protected void onPause() {
         super.onPause();
         // Call disable to ensure that the trigger request has been canceled.
         mSensorManager.cancelTriggerSensor(mListener, mSigMotion);
     }

 }
 

Summary

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 millis, int nanos) Causes the current thread to wait until another thread invokes the notify() method or the notifyAll() method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed. final void wait(long millis) Causes the current thread to wait until either another thread invokes the notify() method or the notifyAll() method for this object, or a specified amount of time has elapsed. final void wait() Causes the current thread to wait until another thread invokes the notify() method or the notifyAll() method for this object.
