↳ | android.view.accessibility.AccessibilityManager |
System level service that serves as an event dispatch for AccessibilityEvent
s,
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);
