public abstract class

OrientationEventListener

extends Object

java.lang.Object
↳	android.view.OrientationEventListener

Class Overview

Helper class for receiving notifications from the SensorManager when the orientation of the device has changed.

Summary

Constants
int	ORIENTATION_UNKNOWN	Returned from onOrientationChanged when the device orientation cannot be determined (typically when the device is in a close to flat position).

Public Constructors
	OrientationEventListener(Context context) Creates a new OrientationEventListener.
	OrientationEventListener(Context context, int rate) Creates a new OrientationEventListener.

Public Methods
boolean	canDetectOrientation()
void	disable() Disables the OrientationEventListener.
void	enable() Enables the OrientationEventListener so it will monitor the sensor and call `onOrientationChanged(int)` when the device orientation changes.
abstract void	onOrientationChanged(int orientation) Called when the orientation of the device has changed.

Inherited Methods

From class java.lang.Object

Object	clone() Creates and returns a copy of this `Object`.
boolean	equals(Object o) Compares this instance with the specified object and indicates if they are equal.
void	finalize() Invoked when the garbage collector has detected that this instance is no longer reachable.
final Class<?>	getClass() Returns the unique instance of `Class` that represents this object's class.
int	hashCode() Returns an integer hash code for this object.
final void	notify() Causes a thread which is waiting on this object's monitor (by means of calling one of the `wait()` methods) to be woken up.
final void	notifyAll() Causes all threads which are waiting on this object's monitor (by means of calling one of the `wait()` methods) to be woken up.
String	toString() Returns a string containing a concise, human-readable description of this object.
final void	wait() Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object.
final void	wait(long millis, int nanos) Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object or until the specified timeout expires.
final void	wait(long millis) Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object or until the specified timeout expires.

Constants

public static final int ORIENTATION_UNKNOWN

Added in API level 3

Returned from onOrientationChanged when the device orientation cannot be determined (typically when the device is in a close to flat position).

Public Constructors

public OrientationEventListener (Context context)

Added in API level 3

Creates a new OrientationEventListener.

Parameters

context	for the OrientationEventListener.

public OrientationEventListener (Context context, int rate)

Added in API level 3

Creates a new OrientationEventListener.

Parameters

context	for the OrientationEventListener.
rate	at which sensor events are processed (see also `SensorManager`). Use the default value of `SENSOR_DELAY_NORMAL` for simple screen orientation change detection.

Public Methods

public boolean canDetectOrientation ()

Added in API level 3

public void disable ()

Added in API level 3

Disables the OrientationEventListener.

public void enable ()

Added in API level 3

Enables the OrientationEventListener so it will monitor the sensor and call onOrientationChanged(int) when the device orientation changes.

public abstract void onOrientationChanged (int orientation)

Added in API level 3

Called when the orientation of the device has changed. orientation parameter is in degrees, ranging from 0 to 359. orientation is 0 degrees when the device is oriented in its natural position, 90 degrees when its left side is at the top, 180 degrees when it is upside down, and 270 degrees when its right side is to the top. ORIENTATION_UNKNOWN is returned when the device is close to flat and the orientation cannot be determined.

Parameters

orientation	The new orientation of the device.
