AccessibilityManager

public final class AccessibilityManager
extends Object

java.lang.Object
↳	android.view.accessibility.AccessibilityManager

System level service that serves as an event dispatch for AccessibilityEvents, and provides facilities for querying the accessibility state of the system. Accessibility events are generated when something notable happens in the user interface, for example an Activity starts, the focus or selection of a View changes etc. Parties interested in handling accessibility events implement and register an accessibility service which extends AccessibilityService.

To obtain a handle to the accessibility manager do the following:

AccessibilityManager accessibilityManager =
        (AccessibilityManager) context.getSystemService(Context.ACCESSIBILITY_SERVICE);

Public methods

addAccessibilityStateChangeListener

added in API level 14

boolean addAccessibilityStateChangeListener (AccessibilityManager.AccessibilityStateChangeListener listener)

Registers an AccessibilityManager.AccessibilityStateChangeListener for changes in the global accessibility state of the system. Equivalent to calling addAccessibilityStateChangeListener(AccessibilityStateChangeListener, Handler) with a null handler.

Parameters
`listener`	`AccessibilityManager.AccessibilityStateChangeListener`: The listener. This value must never be `null`.

Returns
`boolean`	Always returns `true`.

addAccessibilityStateChangeListener

Android O Developer Preview

void addAccessibilityStateChangeListener (AccessibilityManager.AccessibilityStateChangeListener listener, 
                Handler handler)

Registers an AccessibilityManager.AccessibilityStateChangeListener for changes in the global accessibility state of the system. If the listener has already been registered, the handler used to call it back is updated.

Parameters
`listener`	`AccessibilityManager.AccessibilityStateChangeListener`: The listener. This value must never be `null`.
`handler`	`Handler`: The handler on which the listener should be called back, or `null` for a callback on the process's main handler. This value may be `null`.

addTouchExplorationStateChangeListener

Android O Developer Preview

void addTouchExplorationStateChangeListener (AccessibilityManager.TouchExplorationStateChangeListener listener, 
                Handler handler)

Registers an AccessibilityManager.TouchExplorationStateChangeListener for changes in the global touch exploration state of the system. If the listener has already been registered, the handler used to call it back is updated.

Parameters
`listener`	`AccessibilityManager.TouchExplorationStateChangeListener`: The listener. This value must never be `null`.
`handler`	`Handler`: The handler on which the listener should be called back, or `null` for a callback on the process's main handler. This value may be `null`.

addTouchExplorationStateChangeListener

added in API level 19

boolean addTouchExplorationStateChangeListener (AccessibilityManager.TouchExplorationStateChangeListener listener)

Registers a AccessibilityManager.TouchExplorationStateChangeListener for changes in the global touch exploration state of the system. Equivalent to calling addTouchExplorationStateChangeListener(TouchExplorationStateChangeListener, Handler) with a null handler.

Parameters
`listener`	`AccessibilityManager.TouchExplorationStateChangeListener`: The listener. This value must never be `null`.

Returns
`boolean`	Always returns `true`.

getAccessibilityServiceList

added in API level 4

List<ServiceInfo> getAccessibilityServiceList ()

This method was deprecated in API level 14.
Use getInstalledAccessibilityServiceList()

Returns the ServiceInfos of the installed accessibility services.

Returns
`List<ServiceInfo>`	An unmodifiable list with `ServiceInfo`s.

getEnabledAccessibilityServiceList

added in API level 14

List<AccessibilityServiceInfo> getEnabledAccessibilityServiceList (int feedbackTypeFlags)

Returns the AccessibilityServiceInfos of the enabled accessibility services for a given feedback type.

Parameters
`feedbackTypeFlags`	`int`: The feedback type flags.

Returns
`List<AccessibilityServiceInfo>`	An unmodifiable list with `AccessibilityServiceInfo`s.

See also:

getInstalledAccessibilityServiceList

added in API level 14

List<AccessibilityServiceInfo> getInstalledAccessibilityServiceList ()

Returns the AccessibilityServiceInfos of the installed accessibility services.

Returns
`List<AccessibilityServiceInfo>`	An unmodifiable list with `AccessibilityServiceInfo`s.

interrupt

added in API level 4

void interrupt ()

Requests feedback interruption from all accessibility services.

isEnabled

added in API level 4

boolean isEnabled ()

Returns if the accessibility in the system is enabled.

Returns
`boolean`	True if accessibility is enabled, false otherwise.

isTouchExplorationEnabled

added in API level 14

boolean isTouchExplorationEnabled ()

Returns if the touch exploration in the system is enabled.

Returns
`boolean`	True if touch exploration is enabled, false otherwise.

removeAccessibilityStateChangeListener

added in API level 14

boolean removeAccessibilityStateChangeListener (AccessibilityManager.AccessibilityStateChangeListener listener)

Unregisters an AccessibilityManager.AccessibilityStateChangeListener.

Parameters
`listener`	`AccessibilityManager.AccessibilityStateChangeListener`: The listener. This value must never be `null`.

Returns
`boolean`	True if the listener was previously registered.

removeTouchExplorationStateChangeListener

added in API level 19

boolean removeTouchExplorationStateChangeListener (AccessibilityManager.TouchExplorationStateChangeListener listener)

Unregisters a AccessibilityManager.TouchExplorationStateChangeListener.

Parameters
`listener`	`AccessibilityManager.TouchExplorationStateChangeListener`: The listener. This value must never be `null`.

Returns
`boolean`	True if listener was previously registered.

sendAccessibilityEvent

added in API level 4

void sendAccessibilityEvent (AccessibilityEvent event)

Sends an AccessibilityEvent.

Parameters
`event`	`AccessibilityEvent`: The event to send.

Throws
`IllegalStateException`	if accessibility is not enabled. Note: The preferred mechanism for sending custom accessibility events is through calling `requestSendAccessibilityEvent(View, AccessibilityEvent)` instead of this method to allow predecessors to augment/filter events sent by their descendants.
