public OrientationManager(android.hardware.SensorManager sensorManager,
                          android.view.Display display)

Initializes a new instance of OrientationManager, using the specified context to access system services.

方法详细资料

addOnChangedListener

public void addOnChangedListener(OrientationManager.OnChangedListener listener)

Adds a listener that will be notified when the user's location or orientation changes.

removeOnChangedListener

public void removeOnChangedListener(OrientationManager.OnChangedListener listener)

Removes a listener from the list of those that will be notified when the user's location or orientation changes.

hasCompassSensors

public boolean hasCompassSensors()

start

public void start()

Starts tracking the user's location and orientation. After calling this method, any OrientationManager.OnChangedListeners added to this object will be notified of these events.

stop

public void stop()

Stops tracking the user's location and orientation. Listeners will no longer be notified of these events.

hasInterference

public boolean hasInterference()

Gets a value indicating whether there is too much magnetic field interference for the compass to be reliable.

返回:

true if there is magnetic interference, otherwise false

hasLocation

public boolean hasLocation()

Gets a value indicating whether the orientation manager knows the user's current location.

返回:

true if the user's location is known, otherwise false

getHeading

public float getHeading()

Gets the user's current heading, in degrees. The result is guaranteed to be between 0 and 360.

返回:

the user's current heading, in degrees

getPitch

public float getPitch()

Gets the user's current pitch (head tilt angle), in degrees. The result is guaranteed to be between -90 and 90.

返回:

the user's current pitch angle, in degrees

getLocation

public android.location.Location getLocation()

Gets the user's current location.

返回:

the user's current location
